following requirements:’;
(d) In point 1.1.2.1. the following paragraph is added:
‘In the case of a flex fuel H2NG vehicle, the composition range may vary from 0 % hydrogen to a maximum
percentage of hydrogen within the mixture, which shall be specified by the manufacturer. The parent vehicle shall
demonstrate its capability to adapt to any percentage, within the range specified by the manufacturer. It shall also
demonstrate its capability to adapt to any NG/biomethane composition that may occur across the market,
regardless of the percentage of hydrogen in the mixture.’;
(e) Points 1.1.2.2, 1.1.2.3 and 1.1.2.4 are replaced by the following:
‘1.1.2.2. In the case of vehicles fuelled by LPG, NG/biomethane, the parent vehicle shall be tested in the type 1
test on the two extreme gas reference fuels set out in Annex IX. In the case of NG/biomethane, if the
transition from one gas fuel to the other gas fuel is, in practice, aided through the use of a switch, this
switch shall not be used during type-approval.
In the case of flex fuel H2NG vehicles, the parent vehicle shall be tested in the type 1 test with the
following fuel compositions:
— 100 % H-gas.
— 100 % L-gas.
— The mixture of H-gas and the maximum percentage of hydrogen specified by the manufacturer.
— The mixture of L-gas and the maximum percentage of hydrogen specified by the manufacturer.
1.1.2.3. The vehicle is considered to conform if, under the tests and reference fuels mentioned in point 1.1.2.2,
the vehicle complies with the emission limits.
1.1.2.4. In the case of vehicles fuelled by LPG or NG/biomethane, the ratio of emission results “r” shall be

(g) In point 1.1.3, the first paragraph is replaced by the following:
‘For the type-approval of a mono- fuel gas vehicle and bi-fuel gas vehicles operating in gas mode, fuelled by LPG
or NG/biomethane, as a member of the family, a type 1 test shall be performed with one gas reference fuel. This
reference fuel may be either of the gas reference fuels. The vehicle is considered to comply if the following
requirements are met:’;
(h) The following point 1.1.4 is inserted:
‘1.1.4. For the type-approval of a flex fuel H2NG vehicle as a member of a family, two type 1 tests shall be
performed, the first test with 100 % of either G20 or G25, and the second test with the mixture of
hydrogen and the same NG/biomethane fuel used during the first test, with the maximum hydrogen
percentage specified by the manufacturer.
The vehicle tested in accordance with the first paragraph shall be considered as complying if, in addition to
requirements set out in points (a), (e) and (g) of point 1.1.3., the following requirements are met:
(a) if the NG/biomethane fuel is the reference fuel G20, the emission result for each pollutant shall be
multiplied by the relevant factors (r 1 for the first test and r 2 for the second test), calculated in section
1.1.2.5, if the relevant factor > 1; if the correspondent relevant factor < 1, no correction is needed;
(b) if the NG/biomethane fuel is the reference fuel G25, the emission result for each pollutant shall be
divided by the correspondent relevant factor (r 1 for the first test and r 2 for the second test) calculated
in accordance with point 1.1.2.5, if the correspondent relevant factor < 1; if the correspondent relevant
factor > 1, no correction is needed;
(c) on the manufacturer's request the type 1 test must be performed with the four possible combinations
of reference fuels, according to section 1.1.2.5, so that no correction is needed;
(d) if repeated tests are made on the same engine the results on reference fuel G20, or H2G20, and those
on reference fuel G25, or H2G25 with the maximum hydrogen percentage specified by the manu
facturer, shall first be averaged; the “r 1 ” and “r 2 ” factors shall then be calculated from these averaged
results.’;

( 1 ) The hydrogen fuel index is determined by subtracting the total content of non-hydrogen gaseous constituents listed in the table
(Total gases), expressed in mole percent, from 100 mole percent. It is less than the sum of the maximum allowable limits of all
non-hydrogen constituents shown in the Table.
( 2 ) The value of total gases is summation of the values of the non-hydrogen constituents listed in the table, except the particulates.
Type: H2NG
The hydrogen and the NG/biomethane fuels composing a H2NG mixture, must comply separately with their
corresponding characteristics, expressed in this Annex.’;
5. Annex XII is amended as follows:
(a) The title is replaced by the following:
‘DETERMINATION OF CO2 EMISSIONS, FUEL CONSUMPTION, ELECTRIC ENERGY CONSUMPTION AND
ELECTRIC RANGE’;
(b) The introduction is replaced by the following:
‘This Annex sets out the requirements for the measurement of CO2 emissions, fuel consumption, electric energy
consumption and electric range’;
(c) Point 3.1. is replaced by the following:
‘3.1. The technical requirements and specifications for the measurement of CO2 emissions, fuel consumption,
electric energy consumption and electric range shall be those set out in Annexes 6 to 10 to UN/ECE
Regulation 101 with the exceptions specified below’;
