5.1. General
5.1.1. The
components
liable
to
affect
the
emission
of
pollutants
shall
be
so
designed,
constructed
and
assembled as to enable the vehicle, in normal use, despite the vibration to which they may be
subjected, to comply with the provisions of this Regulation.
5.1.2. The
technical
measures
taken
by
the
manufacturer
shall
be
such
as
to
ensure
that
in
conformity
with the provisions of this Regulation, exhaust gas and evaporative emissions are effectively
limited throughout the normal life of the vehicle and under normal conditions of use. This will
include the security of those hoses and their joints and connections, used within the emission
control systems, which shall be so constructed as to conform with the original design intent.
For exhaust emissions, these provisions are deemed to be met if the provisions of paragraphs
5.3.1.4 and 8.2.3.1 respectively are complied with. For evaporative emissions, these conditions
are deemed to be met if the provisions of paragraphs 5.3.1.4 and 8.2.3.1 respectively are
complied with.
5.1.2.1. The
use
of
a
defeat
device
is
prohibited.
5.1.3. Inlet
orifices
of
petrol
tanks
5.1.3.1.

5.1.3.2. Paragraph
5.1.3.1
shall
not
apply
to
a
vehicle
in
respect
of
which
both
of
the
following
conditions are satisfied, i.e.:
5.1.3.2.1. the vehicle is so designed and constructed that no device designed to control the emission of
gaseous pollutants shall be adversely affected by leaded petrol; and
5.1.3.2.2. the vehicle is conspicuously, legibly and indelibly marked with the symbol for unleaded petrol,
specified in ISO 2575:1982, in a position immediately visible to a person filling the petrol tank.
Additional markings are permitted.
5.1.4. Provision
shall
be
made
to
prevent
excess
evaporative
emissions
and
fuel
spillage
caused
by
a
missing fuel filler cap.
This may be achieved by using one of the following:
5.1.4.1. An
automatically
opening
and
closing,
non-removable
fuel
filler
cap;
5.1.4.2. Design
features
which
avoid
excess
evaporative
emissions
in
the
case
of
a
missing
fuel
filler
cap;
5.1.4.3. Any
other
provision
which
has
the
same
effect.
Examples
may
include,
but
are
not
limited
to,
a
tethered filler cap, a chained filler cap or one utilising the same locking key for the filler cap as
for the vehicle’s ignition. In this case, the key shall be removable from the filler cap only in the
locked condition.
5.1.5.
Provisions for electronic system security
5.1.5.1.
Any vehicle with an emission control computer shall include features to deter modification,
except as authorised by the manufacturer. The manufacturer shall authorise modifications if
these modifications are necessary for the diagnosis, servicing, inspection, retrofitting or repair of
the vehicle. Any reprogrammable computer codes or operating parameters shall be resistant to
tampering and afford a level of protection at least as good as the provisions in ISO DIS 15031-
7, dated October 1998 (SAE J2186 dated October 1996), provided that the security exchange is
conducted using the protocols and diagnostic connector as prescribed in paragraph 6.5 of
Annex II, Appendix 1. Any removable calibration memory chips shall be potted, encased in
a sealed container or protected by electronic algorithms and shall not be changeable without
the use of specialised tools and procedures.
5.1.5.2. Computer-coded
engine
operating
parameters
shall
not
be
changeable
without
the
use
of
specialised tools and procedures (e.g. soldered or potted computer components or sealed (or
soldered) computer enclosures).
5.1.5.3. In
the
case
of
mechanical
fuel-injection
pumps
fitted
to
compression-ignition
engines,
manu
facturers shall take adequate steps to protect the maximum fuel delivery setting from tampering
while a vehicle is in service.
5.1.5.4. Manufacturers
may
apply
to
the
Approval
Authority
for
an
exemption
to
one
of
these
requirements for those vehicles which are unlikely to require protection. The criteria that the
Approval Authority will evaluate in considering an exemption will include, but are not limited
to, the current availability of performance chips, the high-performance capability of the vehicle
and the projected sales volume of the vehicle.
5.1.5.5. Manufacturers
using
programmable
computer
code
systems
(e.g.
Electrical
Erasable
Programmable Read-Only Memory, EEPROM) shall deter unauthorised reprogramming. Manu

5.3. Description
of
tests
5.3.1. Type
I
test
(Simulating
the
average
exhaust
emissions
after
a
cold
start).
5.3.1.1.
Figure 1 illustrates the routes for Type I test. This test shall be carried out on all vehicles
referred to in paragraph 1 and its subparagraphs.
5.3.1.2.
The vehicle is placed on a chassis dynamometer equipped with a means of load and inertia
simulation.
5.3.1.2.1. A test lasting a total of 19 minutes and 40 seconds, made up of two parts, One and Two, is
performed without interruption. An unsampled period of not more than 20 seconds may, with
the agreement of the manufacturer, be introduced between the end of Part One and the
beginning of Part Two in order to facilitate adjustment of the test equipment.
5.3.1.2.1.1. Vehicles that are fuelled with LPG or NG/biomethane shall be tested in the Type I test for
variation in the composition of LPG or NG/biomethane, as set out in Annex 12. Vehicles that
can be fuelled either with petrol or LPG or NG/biomethane shall be tested on both the fuels,
tests on LPG or NG/biomethane being performed for variation in the composition of LPG or
NG/biomethane, as set out in Annex 12.
5.3.1.2.1.2. Notwithstanding the requirement of paragraph 5.3.1.2.1.1, vehicles that can be fuelled with
either petrol or a gaseous fuel, but where the petrol system is fitted for emergency purposes or
starting only and which the petrol tank cannot contain more than 15 litres of petrol will be
regarded for the test Type I as vehicles that can only run on a gaseous fuel.
5.3.1.2.2. Part One of the test is made up of four elementary urban cycles. Each elementary urban cycle
comprises fifteen phases (idling, acceleration, steady speed, deceleration, etc.).
5.3.1.2.3. Part Two of the test is made up of one extra-urban cycle. The extra-urban cycle comprises 13
phases (idling, acceleration, steady speed, deceleration, etc.).
5.3.1.2.4. During the test, the exhaust gases are diluted and a proportional sample collected in one or
more bags. The exhaust gases of the vehicle tested are diluted, sampled and analysed, following
the procedure described below, and the total volume of the diluted exhaust is measured. Not
only the carbon monoxide, hydrocarbon and nitrogen oxide emissions but also the particulate
pollutant emissions from vehicles equipped with compression-ignition engines are recorded.
5.3.1.3.
The test is carried out using the procedure of Type I test as described in Annex 4a. The method
used to collect and analyse the gases is prescribed in Appendix 2 and 3 of Annex 4a, and the
method to sample and analyse the particulates shall be as prescribed in Appendix 4 and 5 of
Annex 4a.
5.3.1.4. Subject
to
the
requirements
of
paragraph
5.3.1.5
the
test
shall
be
repeated
three
times.
The
results are multiplied by the appropriate deterioration factors obtained from paragraph 5.3.6
and, in the case of periodically regenerating systems as defined in paragraph 2.20, also must be
multiplied by the factors K i obtained from Annex 13. The resulting masses of gaseous
emissions and, in the case of vehicles equipped with compression-ignition engines, the mass
of particulates obtained in each test shall be less than the limits shown in the Table 1 below:

5.3.1.4.1. Notwithstanding
the
requirements
of
paragraph
5.3.1.4,
for
each
pollutant
or
combination
of
pollutants, one of the three resulting masses obtained may exceed, by not more than 10 per
cent, the limit prescribed, provided the arithmetical mean of the three results is below the
prescribed limit. Where the prescribed limits are exceeded for more than one pollutant, it is
immaterial whether this occurs in the same test or in different tests.
5.3.1.4.2. When
the
tests
are
performed
with
gaseous
fuels,
the
resulting
mass
of
gaseous
emissions
shall
be less than the limits for petrol-engined vehicles in the above table.
5.3.1.5.
The number of tests prescribed in paragraph 5.3.1.4 is reduced in the conditions hereinafter
defined, where V 1 is the result of the first test and V 2 the result of the second test for each
pollutant or for the combined emission of two pollutants subject to limitation.
5.3.1.5.1. Only one test is performed if the result obtained for each pollutant or for the combined
emission of two pollutants subject to limitation, is less than or equal to 0,70 L (i.e. V 1 ≤
0,70 L).
5.3.1.5.2. If the requirement of paragraph 5.3.1.5.1 is not satisfied, only two tests are performed if, for
each pollutant or for the combined emission of two pollutants subject to limitation, the
following requirements are met:
V 1 ≤ 0,85 L and V 1 + V 2 ≤ 1,70 L and V 2 ≤ L.

to
ensure
that in-service performance can be assessed for normal conditions of use as defined in
paragraph 9.2. The manufacturer’s sampling shall be drawn from at least two Contracting
Parties with substantially different vehicle operating conditions. Factors such as differences in

into consideration in the selection of the Contracting Parties.
9.3.2.
In selecting the Contracting Parties for sampling vehicles, the manufacturer may select vehicles
from a Contracting Party that is considered to be particularly representative. In this case, the
manufacturer shall demonstrate to the Approval Authority which granted the type approval
that the selection is representative (e.g. by the market having the largest annual sales of a
vehicle family within the applicable Contracting Party). When an in-service family requires more
than one sample lot to be tested as defined in paragraph 9.3.5, the vehicles in the second and
third sample lots shall reflect different vehicle operating conditions from those selected for the
first sample.
9.3.3.
The emissions testing may be done at a test facility which is located in a different market or
region from where the vehicles have been selected.
9.3.4. The
in-service
conformity
tests
by
the
manufacturer
shall
be
continuously
carried
out
reflecting
the production cycle of applicable vehicles types within a given in-service vehicle family. The
maximum time period between commencing two in-service conformity checks shall not exceed
18 months. In the case of vehicle types covered by an extension to the type approval that did
not require an emissions test, this period may be extended up to 24 months.
9.3.5.
When applying the statistical procedure defined in Appendix 4, the number of sample lots shall
depend on the annual sales volume of an in-service family in the territories of a regional
organisation (e.g. European Community), as defined in the following table:

9.4.
On the basis of the audit referred to in paragraph 9.2, the Approval Authority shall adopt one
of the following decisions and actions:
(a) decide that the in-service conformity of a vehicle type or a vehicle in-service family is
satisfactory and not take any further action;
(b) decide that the data provided by the manufacturer is insufficient to reach a decision and
request additional information or test data from the manufacturer;
(c) decide that based on data from the Approval Authority or Contracting Party surveillance
testing programmes, that information provided by the manufacturer is insufficient to reach
a decision and request additional information or test data from the manufacturer;
(d) decide that the in-service conformity of a vehicle type, that is part of an in-service family, is
unsatisfactory and proceed to have such vehicle type tested in accordance with Appendix 3.
9.4.1. Where
Type
I
tests
are
considered
necessary
to
check
the
conformity
of
emission
control
devices with the requirements for their performance while in service, such tests shall be
carried out using a test procedure meeting the statistical criteria defined in Appendix 2.
9.4.2. The
Approval
Authority,
in
cooperation
with
the
manufacturer,
shall
select
a
sample
of
vehicles
with sufficient mileage whose use under normal conditions can be reasonably assured. The
manufacturer shall be consulted on the choice of the vehicles in the sample and allowed to
attend the confirmatory checks of the vehicles.
9.4.3.
The manufacturer shall be authorised, under the supervision of the Approval Authority, to carry
out checks, even of a destructive nature, on those vehicles with emission levels in excess of the
limit values with a view to establishing possible causes of deterioration which cannot be
attributed to the manufacturer (e.g. use of leaded petrol before the test date). Where the
results of the checks confirm such causes, those test results shall be excluded from the
conformity check.

Appendix 1
Procedure for verifying the conformity of production requirements if the production standard deviation given
by the manufacturer is satisfactory
1. This Appendix describes the procedure to be used to verify the production conformity for the Type I Test when the
manufacturer’s production standard deviation is satisfactory.
2. With a minimum sample size of 3, the sampling procedure is set so that the probability of a lot passing a test with
40 per cent of the production defective is 0,95 (producer’s risk = 5 per cent) while the probability of a lot being
accepted with 65 per cent of the production defective is 0,1 (consumer’s risk = 10 per cent).
3. For each of the pollutants given in Table 1 of paragraph 5.3.1.4 of this Regulation, the following procedure is used
(see Figure 2 of this Regulation).
Taking:
L = the natural logarithm of the limit value for the pollutant,
x i = the natural logarithm of the measurement for the i-th vehicle of the sample,
s = an estimate of the production standard deviation (after taking the natural logarithm of the measurements),
n = the current sample number.
4. Compute for the sample the test statistic quantifying the sum of the standard deviations from the limit and defined
as:
1 n
s X L – x i
i 1
5. Then:
5.1. If the test statistic is greater than the pass decision number for the sample size given in Table 1/1 below, the
pollutant is passed;
5.2. If the test statistic is less than the fail decision number for the sample size given in Table 1/1 below, the pollutant is
failed; otherwise, an additional vehicle is tested and the calculation reapplied to the sample with a sample size one
unit greater.

Appendix 2
Procedure for verifying the conformity of production requirements if the production standard deviation given
by the manufacturer is either not satisfactory or not available
1. This Appendix describes the procedure to be used to verify the production conformity requirements for the Type I test
when the manufacturer’s evidence of production standard deviation is either not satisfactory or not available.
2. With a minimum sample size of 3, the sampling procedure is set so that the probability of a lot passing a test with 40
per cent of the production defective is 0,95 (producer’s risk = 5 per cent) while the probability of a lot being accepted
with 65 per cent of the production defective is 0,l (consumer’s risk = 10 per cent).
3. The measurements of the pollutants given in Table 1 of paragraph 5.3.1.4 of this Regulation are considered to be log
normally distributed and shall first be transformed by taking their natural logarithms. Let m 0 and m denote the
minimum and maximum sample sizes respectively (m 0 = 3 and m = 32) and let n denote the current sample number.
4. If the natural logarithms of the measurements in the series are x 1 , x 2 , x i and L is the natural logarithm of the limit
value for the pollutant, then define:
d 1 = x 1 – L

Appendix 3
In-service conformity check
1. INTRODUCTION
This Appendix sets out the criteria referred to in paragraph 8.2.7 of this Regulation regarding the selection of
vehicles for testing and the procedures for the in-service conformity control.
2. SELECTION
CRITERIA
The criteria for acceptance of a selected vehicle are defined in paragraphs 2.1 to 2.8 of this Appendix.
Information is collected by vehicle examination and an interview with the owner/driver.
2.1.
The vehicle shall belong to a vehicle type that is type approved under this Regulation and covered by a certificate
of conformity in accordance with the 1958 Agreement. It shall be registered and used in a country of the
Contracting Parties.
2.2.
The vehicle shall have been in service for at least 15 000 km or 6 months, whichever is the later, and for no
more than 100 000 km or 5 years, whichever is the sooner.
2.3.
There shall be a maintenance record to show that the vehicle has been properly maintained, e.g. has been serviced
in accordance with the manufacturer’s recommendations.
2.4. The
vehicle
shall
exhibit
no
indications
of
abuse
(e.g.
racing,
overloading,
misfuelling,
or
other
misuse),
or
other
factors (e.g. tampering) that could affect emission performance. In the case of vehicles fitted with an OBD system,
the fault code and mileage information stored in the computer is taken into account. A vehicle shall not be
selected for testing if the information stored in the computer shows that the vehicle has operated after a fault
code was stored and a relatively prompt repair was not carried out.
2.5.
There shall have been no unauthorised major repair to the engine or major repair of the vehicle.
2.6.
The lead content and sulphur content of a fuel sample from the vehicle tank shall meet applicable standards and
there shall be no evidence of misfuelling. Checks may be done in the exhaust, etc.
2.7.
There shall be no indication of any problem that might jeopardise the safety of laboratory personnel.
2.8.
All anti-pollution system components on the vehicle shall be in conformity with the applicable type approval.
3. DIAGNOSIS
AND
MAINTENANCE
Diagnosis and any normal maintenance necessary shall be performed on vehicles accepted for testing, prior to
measuring exhaust emissions, in accordance with the procedure laid down in paragraphs 3.1 to 3.7 below.
3.1.
The following checks shall be carried out: checks on air filter, all drive belts, all fluid levels, radiator cap, all
vacuum hoses and electrical wiring related to the anti-pollution system for integrity; checks on ignition, fuel
metering and anti-pollution device components for maladjustments and/or tampering. All discrepancies shall be
recorded.
3.2. The
OBD
system
shall
be
checked
for
proper
functioning.
Any
malfunction
indications
in
the
OBD
memory
shall
be recorded and the requisite repairs shall be carried out. If the OBD malfunction indicator registers a
malfunction during a preconditioning cycle, the fault may be identified and repaired. The test may be re-run
and the results of that repaired vehicle used.
3.3. The
ignition
system
shall
be
checked
and
defective
components
replaced,
for
example
spark
plugs,
cables,
etc.
3.4.
The compression shall be checked. If the result is unsatisfactory the vehicle is rejected.

EN
15.2.2012 Official
Journal
of
the
European
Union L
42/37
3.5. The
engine
parameters
shall
be
checked
to
the
manufacturer’s
specifications
and
adjusted
if
necessary.
3.6.
If the vehicle is within 800 km of a scheduled maintenance service, that service shall be performed according to
the manufacturer’s instructions. Regardless of odometer reading, the oil and air filter may be changed at the
request of the manufacturer.
3.7.
Upon acceptance of the vehicle, the fuel shall be replaced with appropriate emission test reference fuel, unless the
manufacturer accepts the use of market fuel.
3.8. In
the
case
of
vehicles
equipped
with
periodically
regenerating
systems
as
defined
in
paragraph
2.20,
it
shall
be
established that the vehicle is not approaching a regeneration period (the manufacturer must be given the
opportunity to confirm this).
3.8.1. If this is the case, the vehicle must be driven until the end of the regeneration. If regeneration occurs during
emissions measurement, then a further test must be carried out to ensure that regeneration has been completed.
A complete new test shall then be performed, and the first and second test results not taken into account.
3.8.2. As
an
alternative
to
paragraph
3.8.1,
if
the
vehicle
is
approaching
a
regeneration
the
manufacturer
may
request
that a specific conditioning cycle is used to ensure that regeneration (e.g. this may involve high speed, high load
driving).
The manufacturer may request that testing may be carried out immediately after regeneration or after the
conditioning cycle specified by the manufacturer and normal test preconditioning.
4. IN-SERVICE
TESTING
4.1. When
a
check
on
vehicles
is
deemed
necessary,
emission
tests
in
accordance
with
Annex
4a
to
this
Regulation
are
performed on pre-conditioned vehicles selected in accordance with the requirements of paragraphs 2 and 3 of
this Appendix. Pre-conditioning cycles additional to those specified in paragraph 6.3 of Annex 4a to this
Regulation will only be allowed if they are representative of normal driving.
4.2. Vehicles
equipped
with
an
OBD
system
may
be
checked
for
proper
in-service
functionality
of
the
malfunction
indication, etc., in relation to levels of emissions (e.g. the malfunction indication limits defined in Annex 11 to
this Regulation) for the type approved specifications.
4.3.
The OBD system may be checked, for example, for levels of emissions above the applicable limit values with no
malfunction indication, systematic erroneous activation of the malfunction indication and identified faulty or
deteriorated components in the OBD system.
4.4.
If a component or system operates in a manner not covered by the particulars in the type approval certificate
and/or information package for such vehicle types and such deviation has not been authorised under the 1958
Agreement, with no malfunction indication by the OBD, the component or system shall not be replaced prior to
emission testing, unless it is determined that the component or system has been tampered with or abused in such
a manner that the OBD does not detect the resulting malfunction.
5. EVALUATION
OF
RESULTS
5.1. The
test
results
are
submitted
to
the
evaluation
procedure
in
accordance
with
Appendix
4.
5.2. Test
results
shall
not
be
multiplied
by
deterioration
factors.
5.3.
In the case of periodically regenerating systems as defined in paragraph 2.20, the results shall be multiplied by the
factors K i obtained at the time when type approval was granted.
6. PLAN
OF
REMEDIAL
MEASURES
6.1. When
more
than
one
vehicle
is
found
to
be
an
outlying
emitter
that
either,
(a) meets the conditions of paragraph 3.2.3 of Appendix 4 and where both the Approval Authority and the
manufacturer agree that the excess emission is due to the same cause; or
(b) meets the conditions of paragraph 3.2.4 of Appendix 4 where the Approval Authority has determined that
the excess emission is due to the same cause.

Appendix 4
Statistical procedure for in-service conformity testing
1.
This Appendix describes the procedure to be used to verify the in-service conformity requirements for the Type
I test.
2. Two
different
procedures
are
to
be
followed:
(i) one dealing with vehicles identified in the sample, due to an emission-related defect, causing outliers in the
results (paragraph 3 below);
(ii) the other deals with the total sample (paragraph 4 below).
3. Procedure
to
be
followed
with
outlying
emitters
in
the
sample
3.1.
With a minimum sample size of three and a maximum sample size as determined by the procedure of
paragraph 4, a vehicle is taken at random from the sample and the emissions of the regulated pollutants
are measured to determine if it is an outlying emitter.
3.2. A
vehicle
is
said
to
be
an
outlying
emitter
when
the
conditions
given
in
paragraph
3.2.1
are
met.
3.2.1.
In the case of a vehicle that has been type-approved according to the limit values given in Table 1 in paragraph
5.3.1.4, an outlying emitter is a vehicle where the applicable limit value for any regulated pollutant is exceeded
by a factor of 1,5.
3.2.2.
In the specific case of a vehicle with a measured emission for any regulated pollutant within the ‘intermediate
zone’ ( 1 ).
3.2.2.1. If the vehicle meets the conditions of this paragraph, the cause of the excess emission must be determined and
another vehicle is then taken at random from the sample.
3.2.2.2. Where
more
than
one
vehicle
meets
the
condition
of
this
paragraph,
the
administrative
department
and
the
manufacturer must determine if the excess emission from both vehicles is due to the same cause or not.
3.2.2.2.1. If the administrative department and the manufacturer both agree that the excess emission is due to the same
cause, the sample is regarded as having failed and the plan of remedial measures outlined in paragraph 6 of
Appendix 3 applies.
3.2.2.2.2. If the administrative department and the manufacturer can not agree on either the cause of the excess emission
from an individual vehicle or whether the causes for more than one vehicle are the same, another vehicle is
taken at random from the sample, unless the maximum sample size has already been reached.
3.2.2.3. When
only
one
vehicle
meeting
the
conditions
of
this
paragraph
has
been
found,
or
when
more

one
vehicle has been found and the administrative department and the manufacturer agree it is due to different
causes, another vehicle is taken at random from the sample, unless the maximum sample size has already been
reached.
3.2.2.4. If the maximum sample size is reached and not more than one vehicle meeting the requirements of this
paragraph has been found where the excess emission is due to the same cause, the sample is regarded as having
passed with regard to the requirements of paragraph 3 of this Appendix.
3.2.2.5. If, at any time, the initial sample has been exhausted, another vehicle is added to the initial sample and that
vehicle is taken.
3.2.2.6. Whenever another vehicle is taken from the sample, the statistical procedure of paragraph 4 of this Appendix
is applied to the increased sample.
( 1 ) For any vehicle, the ‘intermediate zone’ is determined as follows: the vehicle shall meet the conditions given in paragraph 3.2.1 and, in
addition, the measured value for the same regulated pollutant shall be below a level that is determined from the product of the limit
value for the same regulated pollutant given in Table 1 in paragraph 5.3.1.4 multiplied by a factor of 2,5.

3.2.3.1. If the vehicle meets the conditions of this paragraph, the administrative department shall determine the cause
of the excess emission and another vehicle is then taken at random from the sample.
3.2.3.2. Where more than one vehicle meets the condition of this paragraph, and the administrative department
determines that the excess emission is due to the same cause, the manufacturer shall be informed that the
sample is regarded as having failed, together with the reasons for that decision, and the plan of remedial
measures outlined in paragraph 6 of Appendix 3 applies.
3.2.3.3. When
only
one
vehicle
meeting
the
conditions
of

one
vehicle has been found and the administrative department has determined that it is due to different causes,
another vehicle is taken at random from the sample, unless the maximum sample size has already been
reached.
3.2.3.4. If the maximum sample size is reached and not more than one vehicle meeting the requirements of this
paragraph has been found where the excess emission is due to the same cause, the sample is regarded as having
passed with regard to the requirements of paragraph 3 of this Appendix.
3.2.3.5. If, at any time, the initial sample has been exhausted, another vehicle is added to the initial sample and that
vehicle is taken.
3.2.3.6. Whenever another vehicle is taken from the sample, the statistical procedure of paragraph 4 of this Appendix
is applied to the increased sample.
3.2.4.
Whenever a vehicle is not found to be an outlying emitter, another vehicle is taken at random from the
sample.
3.3.
When an outlying emitter is found, the cause of the excess emission shall be determined.
3.4.
When more than one vehicle is found to be an outlying emitter, due to the same cause, the sample is regarded
as having failed.
3.5.
When only one outlying emitter has been found, or when more than one outlying emitter is found, but due to
different causes, the sample is increased by one vehicle, unless the maximum sample size has already been
reached.
3.5.1.
When in the increased sample more than one vehicle is found to be an outlying emitter, due to the same
cause, the sample is regarded as having failed.
3.5.2.
When in the maximum sample size not more than one outlying emitter is found, where the excess emission is
due to the same cause, the sample is regarded as having passed with regard to the requirements of paragraph 3
of this Appendix.
3.6. Whenever
a
sample
is
increased
due
to
the
requirements
of
paragraph
3.5,
the
statistical
procedure
of
paragraph 4 below is applied to the increased sample.
4. Procedure
to
be
followed

sample
4.1.
With a minimum sample size of three the sampling procedure is set so that the probability of a batch passing a
test with 40 per cent of the production defective is 0,95 (producer’s risk = 5 per cent) while the probability of
a batch being accepted with 75 per cent of the production defective is 0,15 (consumer’s risk = 15 per cent).
4.2.
For each of the pollutants given in the Table 1 of paragraph 5.3.1.4 of this Regulation, the following procedure
is used (see Figure 4/2 below).
Where:
L = the limit value for the pollutant,
x i = the value of the measurement for the i-th vehicle of the sample,
n = the current sample number.
( 1 ) For any vehicle, the ‘failure zone’ is determined as follows: the measured value for any regulated pollutant exceeds a level that is
determined from the product of the limit value for the same regulated pollutant given in Table 1 in paragraph 5.3.1.4 multiplied by a
factor of 2,5.

Appendix 6
Requirements for vehicles that use a reagent for the exhaust after-treatment system
1. INTRODUCTION
This Annex sets out the requirements for vehicles that rely on the use of a reagent for the after-treatment system in
order to reduce emissions.
2. REAGENT
INDICATION
2.1. The vehicle shall include a specific indicator on the dashboard that informs the driver of low levels of reagent in
the reagent storage tank and of when the reagent tank becomes empty.
3. DRIVER
WARNING
SYSTEM
3.1. The vehicle shall include a warning system consisting of visual alarms that informs the driver when the reagent
level is low, that the tank soon needs to be refilled, or the reagent is not of a quality specified by the manufacturer.
The warning system may also include an audible component to alert the driver.
3.2. The warning system shall escalate in intensity as the reagent approaches empty. It shall culminate in a driver
notification that can not be easily defeated or ignored. It shall not be possible to turn off the system until the
reagent has been replenished.
3.3. The visual warning shall display a message indicating a low level of reagent. The warning shall not be the same as
the warning used for the purposes of OBD or other engine maintenance. The warning shall be sufficiently clear for
the driver to understand that the reagent level is low (e.g. ‘urea level low’, ‘AdBlue level low’, or ‘reagent low’).
3.4. The warning system does not initially need to be continuously activated, however the warning shall escalate so that
it becomes continuous as the level of the reagent approaches the point where the driver inducement system in
paragraph 8 comes into effect. An explicit warning shall be displayed (e.g. ‘fill up urea’’, ‘fill up AdBlue’, or ‘fill up
reagent’). The continuous warning system may be temporarily interrupted by other warning signals providing
important safety related messages.
3.5. The warning system shall activate at a distance equivalent to a driving range of at least 2 400 km in advance of the
reagent tank becoming empty.
4. IDENTIFICATION
OF
INCORRECT
REAGENT
4.1. The vehicle shall include a means of determining that a reagent corresponding to the characteristics declared by the
manufacturer and recorded in Annex 1 to this Regulation is present on the vehicle.
4.2. If the reagent in the storage tank does not correspond to the minimum requirements declared by the manufacturer
the driver warning system in paragraph 3 shall be activated and shall display a message indicating an appropriate
warning (e.g. ‘incorrect urea detected’, ‘incorrect AdBlue detected’, or ‘incorrect reagent detected’). If the reagent
quality is not rectified within 50 km of the activation of the warning system then the driver inducement
requirements of paragraph 8 shall apply.
5. REAGENT
CONSUMPTION
MONITORING
5.1. The
vehicle
shall
include
a
means
of
determining
reagent
consumption
and
providing
off-board
access
to
consumption information.
5.2. Average reagent consumption and average demanded reagent consumption by the engine system shall be available
via the serial port of the standard diagnostic connector. Data shall be available over the previous complete
2 400 km period of vehicle operation.
5.3. In order to monitor reagent consumption, at least the following parameters within the vehicle shall be monitored:
(a) the level of reagent in the on-vehicle storage tank;
(b) the flow of reagent or injection of reagent as close as technically possible to the point of injection into an
exhaust after-treatment system.

---

L 42/46
EN
Official Journal of the European Union
15.2.2012
5.4. A deviation of more than 50 per cent between the average reagent consumption and the average demanded
reagent consumption by the engine system over a period of 30 minutes of vehicle operation, shall result in the
activation of the driver warning system in paragraph 3., which shall display a message indicating an appropriate
warning (e.g. ‘urea dosing malfunction’, ‘AdBlue dosing malfunction’, or ‘reagent dosing malfunction’). If the
reagent consumption is not rectified within 50 km of the activation of the warning system then the driver
inducement requirements of paragraph 8 shall apply.
5.5. In the case of interruption in reagent dosing activity the driver warning system as referred to in paragraph 3 shall
be activated, which shall display a message indicating an appropriate warning. This activation shall not be required
where the interruption is demanded by the engine ECU because the vehicle operating conditions are such that the
vehicle’s emission performance does not require reagent dosing, provided that the manufacturer has clearly
informed the Approval Authority when such operating conditions apply. If the reagent dosing is not rectified
within 50 km of the activation of the warning system then the driver inducement requirements of paragraph 8
shall apply.
6. MONITORING
NO X EMISSIONS
6.1. As
an
alternative
to
the
monitoring
requirements
in
paragraphs
4
and
5,
manufacturers
may
use
exhaust
gas
sensors directly to sense excess NO x levels in the exhaust.
6.2. The
manufacturer
shall
demonstrate
that
use
of
these
sensors,
and
any
other
sensors
on
the
vehicle,
results
in
the
activation of the driver warning system as referred to in paragraph 3, the display of a message indicating an
appropriate warning (e.g. ‘emissions too high — check urea’, ‘emissions too high — check AdBlue’, ‘emissions too
high — check reagent’), and the driver inducement system as referred to in paragraph 8.3, when the situations
referred to in paragraph 4.2, 5.4 or 5.5 occur.
7. STORAGE
OF
FAILURE
INFORMATION
7.1. Where
reference
is
made
to
this
paragraph,
a
non-erasable
Parameter
Identifier
(PID)
shall
be
stored
identifying
the
reason for the inducement system activation. The vehicle shall retain a record of the PID and the distance travelled
by the vehicle during the inducement system activation for at least 800 days or 30 000 km of vehicle operation.
The PID shall be made available via the serial port of a standard diagnostic connector upon request of a generic
scan tool.
7.2. Malfunctions
in
the
reagent
dosing
system
attributed
to
technical
failures
(e.g.
mechanical
or
electrical
faults)
shall
also be subject to the OBD requirements in Annex 11.
8. DRIVER
INDUCEMENT
SYSTEM
8.1. The
vehicle
shall
include
a
driver
inducement
system
to
ensure
that
the
vehicle
operates
with
a
functioning
emissions control system at all times. The inducement system shall be designed so as to ensure that the
vehicle can not operate with an empty reagent tank.
8.2. The inducement system shall activate at the latest when the level of reagent in the tank reaches a level equivalent
to the average driving range of the vehicle with a complete tank of fuel. The system shall also activate when the
failures in paragraphs 4, 5 or 6 have occurred, depending on the NO x monitoring approach. The detection of an
empty reagent tank and the failures mentioned in paragraphs 4, 5 or 6 shall result in the failure information
storage requirements of paragraph 7 coming into effect.
8.3. The manufacturer shall select which type of inducement system to install. The options for a system are described
in paragraphs 8.3.1, 8.3.2, 8.3.3 and 8.3.4.
8.3.1. A ‘no engine restart after countdown’ approach allows a countdown of restarts or distance remaining once the
inducement system activates. Engine starts initiated by the vehicle control system, such as start-stop systems, are
not included in this countdown. Engine restarts shall be prevented immediately after the reagent tank becomes
empty or a distance equivalent to a complete tank of fuel has been exceeded since the activation of the inducement
system, whichever occurs earlier.
8.3.2. A ‘no start after refuelling’ system results in a vehicle being unable to start after re-fuelling if the inducement
system has activated.
8.3.3. A ‘fuel-lockout’ approach prevents the vehicle from being refuelled by locking the fuel filler system after the
inducement system activates. The lockout system shall be robust to prevent it being tampered with.

---

EN
15.2.2012 Official
Journal
of
the
European
Union L
42/47
8.3.4. A ‘performance restriction’ approach restricts the speed of the vehicle after the inducement system activates. The
level of speed limitation shall be noticeable to the driver and significantly reduce the maximum speed of the
vehicle. Such limitation shall enter into operation gradually or after an engine start. Shortly before engine restarts
are prevented, the speed of the vehicle shall not exceed 50 km/h. Engine restarts shall be prevented immediately
after the reagent tank becomes empty or a distance equivalent to a complete tank of fuel has been exceeded since
the activation of inducement system, whichever occurs earlier.
8.4. Once the inducement system has fully activated and disabled the vehicle, the inducement system shall only be
deactivated if the quantity of reagent added to the vehicle is equivalent to 2 400 km average driving range, or the
failures specified in paragraphs 4, 5, or 6 have been rectified. After a repair has been carried out to correct a fault
where the OBD system has been triggered under paragraph 7.2, the inducement system may be reinitialised via the
OBD serial port (e.g. by a generic scan tool) to enable the vehicle to be restarted for self-diagnosis purposes. The
vehicle shall operate for a maximum of 50 km to enable the success of the repair to be validated. The inducement
system shall be fully reactivated if the fault persists after this validation.
8.5. The driver warning system referred to in paragraph 3 shall display a message indicating clearly:
(a) the number of remaining restarts and/or the remaining distance; and
(b) the conditions under which the vehicle can be restarted.
8.6. The
driver
inducement
system
shall
be
deactivated
when
the
conditions
for
its
activation
have
ceased
to
exist.
The
driver inducement system shall not be automatically deactivated without the reason for its activation having been
remedied.
8.7. Detailed
written
information
fully
describing
the
functional
operation
characteristics
of
the
driver
inducement
system shall be provided to the Approval Authority at the time of approval.
8.8. As part of the application for type approval under this Regulation, the manufacturer shall demonstrate the
operation of the driver warning and inducement systems.
9. INFORMATION
REQUIREMENTS
9.1. The manufacturer shall provide all owners of new vehicles written information about the emission control system.
This information shall state that if the vehicle emission control system is not functioning correctly, the driver shall
be informed of a problem by the driver warning system and that the driver inducement system shall consequen
tially result in the vehicle being unable to start.
9.2. The instructions shall indicate requirements for the proper use and maintenance of vehicles, including the proper
use of consumable reagents.
9.3. The instructions shall specify if consumable reagents have to be refilled by the vehicle operator between normal
maintenance intervals. They shall indicate how the driver should refill the reagent tank. The information shall also
indicate a likely rate of reagent consumption for that type of vehicle and how often it should be replenished.
9.4. The
instructions
shall
specify
that
use
of,
and
refilling
of,
a
required
reagent
of
the
correct
specifications
is
mandatory for the vehicle to comply with the certificate of conformity issued for that vehicle type.
9.5. The instructions shall state that it may be a criminal offence to use a vehicle that does not consume any reagent if
it is required for the reduction of emissions.
9.6. The
instructions
shall
explain
how
the
warning
system
and
driver
inducement
systems
work.
In
addition,
the
consequences of ignoring the warning system and not replenishing the reagent shall be explained.
10. OPERATING
CONDITIONS
OF
THE
AFTER-TREATMENT
SYSTEM
Manufacturers shall ensure that the emission control system retains its emission control function during all
ambient conditions, especially at low ambient temperatures. This includes taking measures to prevent the
complete freezing of the reagent during parking times of up to 7 days at 258 K (– 15 °C) with the reagent
tank 50 per cent full. If the reagent has frozen, the manufacturer shall ensure that reagent shall be available for use
within 20 minutes of the vehicle starting at 258 K (– 15 °C) measured inside the reagent tank, so as to ensure
correct operation of the emission control system.

OBD-related information
As noted in item 3.2.12.2.7.6 of the information document in Annex 1 to this Regulation, the information in this
Appendix is provided by the vehicle manufacturer for the purposes of enabling the manufacture of OBD-compatible
replacement or service parts and diagnostic tools and test equipment.
Upon request, the following information shall be made available to any interested component, diagnostic tools or test
equipment manufacturer, on a non-discriminatory basis.
1. A description of the type and number of the pre-conditioning cycles used for the original type approval of the vehicle.
2. A description of the type of the OBD demonstration cycle used for the original type approval of the vehicle for the
component monitored by the OBD system.
3. A comprehensive document describing all sensed components with the strategy for fault detection and MI activation
(fixed number of driving cycles or statistical method), including a list of relevant secondary sensed parameters for each
component monitored by the OBD system and a list of all OBD output codes and format used (with an explanation of
each) associated with individual emission related power-train components and individual non-emission related
components, where monitoring of the component is used to determine MI activation. In particular, a comprehensive
explanation for the data given in service $05 Test ID $21 to FF and the data given in service $06 shall be provided. In
the case of vehicle types that use a communication link in accordance with ISO 15765-4 ‘Road vehicles — Diagnostics
on Controller Area Network (CAN) — Part 4: Requirements for emissions-related systems’, a comprehensive expla
nation for the data given in service $06 Test ID $00 to FF, for each OBD monitor ID supported, shall be provided.

the second, third, fourth and fifth gears for the extra-urban cycle (Part Two) when the manufacturer’s
instructions recommend starting in second gear on level ground, or when first gear is therein defined as a
gear reserved for cross-country driving, crawling or towing.
Vehicles which do not attain the acceleration and maximum speed values required in the operating cycle shall
be operated with the accelerator control fully depressed until they once again reach the required operating
curve. Deviations from the operating cycle shall be recorded in the test report.
Vehicles equipped with semi-automatic-shift gearboxes shall be tested by using the gears normally employed
for driving, and the gear shift is used in accordance with the manufacturer’s instructions.
6.1.3.2. Vehicles equipped with automatic-shift gearboxes shall be tested with the highest gear (Drive) engaged. The
accelerator shall be used in such a way as to obtain the steadiest acceleration possible, enabling the various
gears to be engaged in the normal order. Furthermore, the gear-change points shown in Tables 1 and 2 of this
Annex shall not apply; acceleration shall continue throughout the period represented by the straight line
connecting the end of each period of idling with the beginning of the next following period of steady
speed. The tolerances given in paragraphs 6.1.3.4 and 6.1.3.5 below shall apply.
6.1.3.3. Vehicles equipped with an overdrive that the driver can actuate shall be tested with the overdrive out of action
for the urban cycle (Part One) and with the overdrive in action for the extra-urban cycle (Part Two).
6.1.3.4. A tolerance of ± 2 km/h shall be allowed between the indicated speed and the theoretical speed during
acceleration, during steady speed, and during deceleration when the vehicle’s brakes are used. If the vehicle
decelerates more rapidly without the use of the brakes, only the provisions of paragraph 6.4.4.3 below shall
apply. Speed tolerances greater than those prescribed shall be accepted during phase changes provided that the
tolerances are never exceeded for more than 0,5 s on any one occasion.
6.1.3.5. The time tolerances shall be ± 1 s. The above tolerances shall apply equally at the beginning and at the end of
each gear-changing period for the urban cycle (Part One) and for the operations Nos 3, 5 and 7 of the extra-
urban cycle (Part Two). It should be noted that the time of two seconds allowed includes the time for changing
gear and, if necessary, a certain amount of latitude to catch up with the cycle.
6.2. Test
preparation
6.2.1. Load
and
inertia
setting
6.2.1.1. Load
determined
with
vehicle
road
test
The dynamometer shall be adjusted so that the total inertia of the rotating masses will simulate the inertia and
other road load forces acting on the vehicle when driving on the road. The means by which this load is
determined is described in paragraph 5 of this Annex.
Dynamometer with fixed load curve: the load simulator shall be adjusted to absorb the power exerted on the
driving wheels at a steady speed of 80 km/h and the absorbed power at 50 km/h shall be noted.
Dynamometer with adjustable load curve: the load simulator shall be adjusted in order to absorb the power
exerted on the driving wheels at steady speeds of 120, 100, 80, 60 and 40 and 20 km/h.
6.2.1.2. Load
determined
by
vehicle
reference
mass
With the manufacturer’s agreement the following method may be used.
The brake is adjusted so as to absorb the load exerted at the driving wheels at a constant speed of 80 km/h, in
accordance with Table 3.
If the corresponding equivalent inertia is not available on the dynamometer, the larger value closest to the
vehicle reference mass will be used.
In the case of vehicles other than passenger cars, with a reference mass of more than 1 700 kg or vehicles with
permanent all-wheel drive, the power values given in Table 3 are multiplied by a factor 1,3.

6.2.2. Preliminary
testing
cycles
Preliminary testing cycles should be carried out if necessary to determine how best to actuate the accelerator
and brake controls so as to achieve a cycle approximating to the theoretical cycle within the prescribed limits
under which the cycle is carried out.
6.2.3. Tyre
pressures
The tyre pressures shall be the same as that specified by the manufacturer and used for the preliminary road
test for brake adjustment. The tyre pressure may be increased by up to 50 per cent from the manufacturer’s
recommended setting in the case of a two-roller dynamometer. The actual pressure used shall be recorded in
the test report.
6.2.4. Background
particulate
mass
measurement
The particulate background level of the dilution air may be determined by passing filtered dilution air through
the particulate filter. This shall be drawn from the same point as the particulate sample. One measurement may
be performed prior to or after the test. Particulate mass measurements may be corrected by subtracting the
background contribution from the dilution system. The permissible background contribution shall be
≤ 1 mg/km (or equivalent mass on the filter). If the background exceeds this level, the default figure of
1 mg/km (or equivalent mass on the filter) shall be employed. Where subtraction of the background
contribution gives a negative result, the particulate mass result shall be considered to be zero.
6.2.5. Background
particle
number
measurements
The subtraction of background particle numbers may be determined by sampling dilution air drawn from a
point downstream of the particle and hydrocarbon filters into the particle number measurement system.
Background correction of particle number measurements shall not be allowed for type approval, but may
be used at the manufacturer’s request for conformity of production and in service conformity where there are
indications that tunnel contribution is significant.
6.2.6. Particulate
mass
filter
selection
A single particulate filter without back-up shall be employed for both urban and extra-urban phases of the
cycle combined.
Twin particulate filters, one for the urban, one for the extra-urban phase, may be used without back-up filters,
only where the pressure-drop increase across the sample filter between the beginning and the end of the
emissions test is otherwise expected to exceed 25 kPa.

air-conditioned chamber. After this conditioning, the uncontaminated filters will be weighed and stored until
they are used. If the filters are not used within 1 hour of their removal from the weighing chamber they shall
be re-weighed.
6.2.7.2. The one-hour limit may be replaced by an eight-hour limit if one or both of the following conditions are met:
6.2.7.2.1. A stabilised filter is placed and kept in a sealed filter holder assembly with the ends plugged; or
6.2.7.2.2. A stabilised filter is placed in a sealed filter holder assembly which is then immediately placed in a sample line
through which there is no flow.

particle sampling system shall be confirmed according to Appendix 5, paragraphs 2.3.1 and 2.3.3:
The particle counter response shall be tested at near zero prior to each test and, on a daily basis, at high
particle concentrations using ambient air.

When the inlet is equipped with a HEPA filter, it shall be demonstrated that the entire particle sampling system
is free from any leaks.
6.2.9. Checking
the
gas
analysers
The emissions analysers for the gases shall be set at zero and spanned. The sample bags shall be evacuated.
6.3. Conditioning
procedure
6.3.1.
For the purpose of measuring particulates, at most 36 hours and at least 6 hours before testing, the Part Two
cycle described in paragraph 6.1 of this Annex shall be used for vehicle pre-conditioning. Three consecutive
cycles shall be driven. The dynamometer setting shall be indicated as in paragraph 6.2.1 above.
At the request of the manufacturer, vehicles fitted with indirect injection positive-ignition engines may be
preconditioned with one Part One and two Part Two driving cycles.
In a test facility in which there may be possible contamination of a low particulate emitting vehicle test with
residue from a previous test on a high particulate emitting vehicle, it is recommended, for the purpose of
sampling equipment pre-conditioning, that a 120 km/h steady state drive cycle of 20 minutes duration
followed by three consecutive Part Two cycles be driven by a low particulate emitting vehicle.
After this preconditioning, and before testing, vehicles shall be kept in a room in which the temperature
remains relatively constant between 293 and 303 K (20 °C and 30 °C). This conditioning shall be carried out
for at least 6 hours and continue until the engine oil temperature and coolant, if any, are within ± 2 K of the
temperature of the room.
If the manufacturer so requests, the test shall be carried out not later than 30 hours after the vehicle has been
run at its normal temperature.
6.3.3.
For positive-ignition engined vehicles fuelled with LPG or NG/biomethane or so equipped that they can be
fuelled with either petrol or LPG or NG/biomethane, between the tests on the first gaseous reference fuel and
the second gaseous reference fuel, the vehicle shall be preconditioned before the test on the second reference
fuel. This preconditioning is done on the second reference fuel by driving a preconditioning cycle consisting of
one Part One (urban part) and two times Part Two (extra-urban part) of the test cycle described in Appendix 1
to this Annex. On the manufacturer’s request and with the agreement of the technical service this precon
ditioning may be extended. The dynamometer setting shall be the one indicated in paragraph 6.2 of this
Annex.
6.4. Test

6.4.3. Accelerations
6.4.3.1. Accelerations shall be so performed that the rate of acceleration is as constant as possible throughout the
operation.
6.4.3.2. If an acceleration cannot be carried out in the prescribed time, the extra time required shall be deducted from
the time allowed for changing gear, if possible, but otherwise from the subsequent steady-speed period.
6.4.3.3. Automatic-shift

6.4.4. Decelerations
6.4.4.1. All decelerations of the elementary urban cycle (Part One) shall be effected by removing the foot completely
from the accelerator with the clutch remaining engaged. The clutch shall be disengaged, without use of the gear
lever, at the higher of the following speeds: 10 km/h or the speed corresponding to the engine idle speed.
All decelerations of the extra-urban cycle (Part Two) shall be effected by removing the foot completely from
the accelerator, the clutch remaining engaged. The clutch shall be disengaged, without use of the gear lever, at a
speed of 50 km/h for the last deceleration.
6.4.4.2. If the period of deceleration is longer than that prescribed for the corresponding phase, the vehicle’s brakes
shall be used to enable compliance with the timing of the cycle.
6.4.4.3. If the period of deceleration is shorter than that prescribed for the corresponding phase, the timing of the
theoretical cycle shall be restored by constant speed or an idling period merging into the following operation.
6.4.4.4. At the end of the deceleration period (halt of the vehicle on the rollers) of the elementary urban cycle (Part
One), the gears shall be placed in neutral and the clutch engaged.
6.4.5. Steady
speeds
6.4.5.1. ‘Pumping’ or the closing of the throttle shall be avoided when passing from acceleration to the following steady
speed.
6.4.5.2. Periods
of
constant
speed
shall
be
achieved
by
keeping
the
accelerator
position
fixed.
6.4.6. Sampling
Sampling shall begin (BS) before or at the initiation of the engine start up procedure and end on conclusion of
the final idling period in the extra-urban cycle (Part Two, end of sampling (ES)) or, in the case of test Type VI,
on conclusion of the final idling period of the last elementary urban cycle (Part One).
6.4.7.
During the test the speed is recorded against time or collected by the data-acquisition system so that the
correctness of the cycles performed can be assessed.
6.4.8.
Particles shall be measured continuously in the particle sampling system. The average concentrations shall be
determined by integrating the analyser signals over the test cycle.
6.5. Post-test
procedures
6.5.1. Gas
analyser
check
Zero and span gas reading of the analysers used for continuous measurement shall be checked. The test shall
be considered acceptable if the difference between the pre-test and post-test results is less than 2 per cent of
the span gas value.
6.5.2. Particulate
filter
weighing
Reference filters shall be weighed within 8 hours of the test filter weighing. The contaminated particulate test
filter shall be taken to the weighing chamber within 1 hour following the analyses of the exhaust gases. The
test filter shall be conditioned for at least 2 hours and not more than 80 hours and then weighed.
6.5.3. Bag
analysis
6.5.3.1. The exhaust gases contained in the bag shall be analysed as soon as possible and in any event not later than 20
minutes after the end of the test cycle.
6.5.3.2. Prior to each sample analysis, the analyser range to be used for each pollutant shall be set to zero with the
appropriate zero gas.
6.5.3.3. The analysers shall then be set to the calibration curves by means of span gases of nominal concentrations of
70 to 100 per cent of the range.
6.5.3.4. The
analysers’
zero
settings
shall
then
be
rechecked:
if
any
reading
differs
by
more
than
2
per
cent
of
the
range
from that set in paragraph 6.5.3.2 above, the procedure shall be repeated for that analyser.
6.5.3.5. The
samples
shall
then
be
analysed.
6.5.3.6. After the analysis, zero and span points shall be rechecked using the same gases. If these rechecks are within ±
2 per cent of those in paragraph 6.5.3.3 above, the analysis shall be considered acceptable.
