6.5.3.1. A tyre which, after undergoing the relevant load/speed test, does not exhibit any tread separation, ply separation, cord separation or broken cords is deemed to have passed the test. The tyre tested shall not be used for any other tests.

6.5.3.2. A tyre which, after undergoing the relevant load/speed test, does exhibit chunking, due to the specific test conditions is deemed to have passed the test.

6.5.4. Where a tyre manufacturer produces a range of tyres it is not considered necessary to carry out tests on every type of tyre in the range.

7. MODIFICATION OF TYRE TYPE AND EXTENSION OF APPROVAL

7.1. Every modification of a tyre type shall be notified to the administrative department which approved the tyre type. That department may then either:

7.1.1. Consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the tyre still meet the requirements; or

8.1. The pneumatic tyres approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set forth in paragraph 6 above.

8.2. The authority which has granted type approval may at any time verify the conformity control methods applied in each production facility. For each production facility, the normal frequency of these verifications shall be once every two years.

9. PENALTIES FOR NON-CONFORMITY OF PRODUCTION

9.1. The approval granted in respect of a type of pneumatic tyre pursuant to this Regulation may be withdrawn if the requirement laid down in paragraph 8.1 above is not complied with or if the tyres taken from the series have failed to pass the tests prescribed in that paragraph.

10. PRODUCTION DEFINITELY DISCONTINUED

If the holder of an approval completely ceases to manufacture a type of pneumatic tyre approved in accordance with this Regulation, he shall so inform the authority which granted the approval. Upon receiving the relevant communication that authority shall inform thereof the other Parties to the Agreement which apply this Regulation by means of a communication form conforming to the model in annex 1 to this Regulation.

Notes:

1. The Tyre size designation may be suplemented by an additional figure: ex: 23,1/18 - 26

instead of 23,1 - 26.

2. Tyres of radial structure are identified by means of the letter "R" in place of "-" (e.g. 23.1R26).

3. Coefficient for the calculation of the overall width: + 8 %

Notes:

1. These Tyres may be classified in categories of use "Tractor Drive Wheels" or "Implement".

2. Implement Tyres are identified either by suffix "IMP" placed after the Tyre size designation (e.g. 11×4.00 - 4 IMP)or by the word "IMPLEMENT" marked on the Tyre sidewalls.

3. Tyres of radial structure are identified by means of the letter "R" in place of "-" (e.g. 11×4.00 R 4).

4. Coefficient "b" for the calculation of the Overall diameter Dmax:

(a) 1,12 for tyres with Nominal rim Diameter (d) less than 380 mm;

(b) 1,10 for tyres with Nominal rim Diameter (d) 381 mm and above.

--------------------------------------------------

ANNEX 6

TEST METHOD FOR MEASURING TYRE DIMENSIONS

1. The tyre shall be mounted on the measuring rim specified by the manufacturer and is inflated to a pressure specified by the manufacturer.

1.1. To seat the beads do not exceed the inflation pressure marked on the tyre sidewalls.

1.2. Having properly seated tyre beads on the rim, adjust the pressure to the value specified for tyre measurements.

2. The tyre fitted on its rim is conditioned to the ambient temperature of the laboratory for at least 24 hours.

3. The pressure is readjusted to the value specified in paragraph 1.

4. The overall width is measured by calliper at six equally-paced points, account being taken of the thickness of the protective ribs or bands. The highest measurement so obtained is taken as the overall width.

5. The outer diameter is determined by measuring the maximum circumference and dividing the figure so obtained by π (3,1416).

ANNEX 8

Test procedure to assess tyre resistance to bursting

1. PREPARING THE TYRE

1.1. Mount a new tyre on the test equipment. Wheels used for the test shall be suitable to withstand, with no deformation, the highest value of pressure achievable during the test.

1.2. Carefully centre the tyre beads on the retention device and adjust the outer distance of the tyre beads to a value corresponding to the width of the rim specified by the manufacturer pursuant to paragraph 4.1.10 of this Regulation.

1.3. Fill the tyre with water taking care that all the air inside the tyre is expelled.

2. TEST PROCEDURE

2.1. Activate the apparatus and increase the pressure of the water inside the tyre in order to reach progressively the limit given by two and half times the pressure specified by the tyre manufacturer pursuant to paragraph 4.1.12 of this Regulation;

2.1.1. in no case, however, the limit value shall be lower than 6 bar (600 kPa) or higher than 10 bar (1000 kPa);

2.2. Maintain constant the value of the pressure for at least 10 minutes.

2.3. Decrease, progressively, the pressure of the water to zero and drain the tyre.

2.4. Whilst the pressure of the water inside the tyre is higher than the ambient pressure, nobody shall stand inside the test room, that shall be safely locked.

3. EQUIVALENT TEST METHODS

If a method other than that described above is used, its equivalence must be demonstrated.

--------------------------------------------------

ANNEX 9

2.2. Use a new inner tube when testing tyres with inner tubes (i.e. tyres not bearing the marking "Tubeless").

2.3. With the tyre beads properly seated on the rim, inflate the tyre to the pressure corresponding to the test pressure specified by the tyre manufacturer for the type of test programme, pursuant to paragraph 4.1.15 of this Regulation.

2.4. Condition the tyre and wheel assembly at test room temperature for not less than three hours.

2.5. Readjust the tyre pressure to that specified in paragraph 2.3 above.

2.6. On request of the tyre manufacturer proceed with the test programme as specified in either of the following paragraphs:

test procedure in a laboratory on a test drum (paragraph 3 below), or

test procedure on a road using a trailer (paragraph 4).

3. TEST PROCEDURE ON A TEST DRUM

3.1. Mount the tyre and wheel assembly on the test axle and press it against the outer face of a smooth power-driven test drum of at least 1700 mm ± 1 per cent in diameter having a surface at least as wide as the tyre tread.

3.1.1. Drum widths narrower than the tyre tread pattern may be used if the tyre manufacturer agrees.

3.2. Test drum speed: 20 km/h.

3.3. Apply to test axle a series of masses in accordance with the load/speed test programme shown in paragraph 3.4 below, with reference to the test load which equates:

3.3.1. the mass corresponding to load index marked on the tyre in case of tyres marked with speed symbol D.

3.4. Load/speed test programme:

Tyre speed category symbol | test step | percentage of the test load | duration (hours) |

D | 1 | 66 % | 7 |

2 | 84 % | 16 |

3 | 101 % | 24 |

3.4.1. In case of a test drum diameter larger than 1700 mm ± 1 per cent, the above "percentage of test load" shall be increased as follows:

F1 = K × F2

K =

×

R

+ r

T

R1 is the diameter of test drum, in millimeter

R2 is the diameter of the reference test drum of 1700 mm

rT is the tyre outer diameter (see paragraph 6.2 of this Regulation), in millimeter

F1 is the percentage of load to be applied for the test drum

F2 is the percentage of load, as per above table, to be applied for reference test drum of 1700 mm

Example: K = 1 for a test drum diameter of 1700 mm;

In case of a test drum diameter of 3000 mm and a tyre diameter of 1500 mm:

K =

×

= 1,12

3.5. The tyre pressure must not be corrected throughout the test and the test load must be kept constant throughout each of the three test steps.

3.6. During the test the temperature in the test room must be maintained at between 20 °C and 30 °C or at another temperature if the manufacturer so agrees.

3.7. The load/speed test programme must be carried out without interruption.

4. TEST PROCEDURE ON A TRAILER

4.1. Mount two new tyres of the same type on a trailer

4.2. Apply on the trailer a mass in order that each tyre be equally loaded with a test load corresponding to the load carrying capacity allowed for that tyre type at 15 km/h (see load variations in annex 7).

4.3. Run the trailer at a constant speed of 15 km/h ± 1 km/h for 48 hours.

4.3.1. Temporary interruptions are allowed, but they must be compensated by an additional run-in of 5 min for every 20 minutes of interruption.

4.4. The tyre pressure must not be corrected and the test load must be kept constant throughout the test.

4.5. During the test the ambient temperature shall be between 5 °C and 30 °C or at another temperature if the manufacturer so agrees.
