...

- Inflate the tyre to the pressure specified by the manufacturer pursuant to Paragraph 3.2.1.13 of this Regulation.

3.1.3. Condition the tyre-and-wheel assembly at test room’s temperature for not less than 03 hours.

3.1.4. Readjust the tyre pressure to that specified in Paragraph 3.1.2.1 or 3.1.2.2 of this Annex.

3.1.5. The manufacturer may request the use of a test-inflation pressure differing from those given under Clause 3.1.2 of this Annex. In such a case, the tyre shall be inflated to the pressure requested by the manufacturer.

3.2. Carrying out the test

3.2.1. With regard to cars and trailers towed by a car:

3.2.1.1. Mount the tyre-and-wheel assembly on a test axle and press it against the outer face of a smooth test drum 1.70 m ± 1% or 2 m ± 1% in diameter.

3.2.1.2. Apply to the test axle a load equal to 80% of:

- The maximum load rating equated to the load capacity index for tyres with speed symbols L to H inclusive.

...

...

...

- The maximum load rating associated with a maximum speed of 270 km/h for tyres with speed symbol "W" (see Paragraph 1.3.34.3 of this Regulation).

- The maximum load rating associated with a maximum speed of 300 km/h for tyres with speed symbol "Y" (see Paragraph 1.3.34.4 of this Regulation).

3.2.1.3. Throughout the test, the tyre pressure must not be adjusted and the test load must be kept constant.

3.2.1.4. During the test, the temperature in the test room must be maintained at between 20°C and 30°C or at a higher temperature if the manufacturer agrees.

3.2.1.5. Carry out the test continuously, without interruption, in conformity with the following steps:

- Pass from zero speed to initial test speed in 10 minutes.

- Initial test speed:

+ 30 km/h less than the maximum nominal speed of the tyre if the test drum is 2.0 m in diameter,

+ 40 km/h less than the initial speed if the test drum is 1.7 m in diameter.

...

...

...

- Duration of test at each step: 10 minutes (except the last step).

- Duration of test at the last step: 20 minutes.

- Total test duration: 1 hour.

- Maximum test speed:

+ The maximum nominal speed of the tyre if the test drum is 2.0 m in diameter;

+ 10 km/h less than the maximum nominal speed of the tyre if the test drum is 1.7 m in diameter.

However, for tyres suitable for maximum speed of 300 km/h (symbol “Y”), the duration of the test is 20 minutes at the last speed step

3.2.2. For other automobiles, trailers and semi-trailers towed by such automobiles:

3.2.1.1. Mount the tyre-and-wheel assembly on a test axle and press it against the outer face of a test drum 1.70 m ± 1% or 2 m ± 1% in diameter.

...

...

...

3.2.2.2.1. For tyres with speed category symbols “Q” and above, the test procedure is defined in Clause 3.3 of this Annex.

3.2.2.2.2. For other types of tyre, the endurance test procedure is specified in Clause 3.4 of this Annex.

3.2.2.3. Throughout the test, the tyre pressure must not be adjusted and the test load must be kept constant.

3.2.2.4. During the test, the temperature in the test room must be maintained at between 20°C and 30°C or at a higher temperature if the manufacturer agrees.

3.2.2.5. Carry out the test continuously, without interruption.

3.3. The following procedure of load/ speed performance applies to tyres with speed category symbols "Q" and above and load capacity indices below:

+ All tyres marked with load capacity index in single 121 or less.

+ Tyres marked with load capacity index in single 122 and above and with the additional marking "C", or "LT".

- Place on the test rim a load that is:

...

...

...

+ 92% of the load corresponding to the load capacity index of the tyre when tested on a test drum 2.0 m ± 1% in diameter.

- Initial test speed:  20 km/h less than that corresponding to the speed category symbol of the tyre.

- Reach the initial test speed from zero speed in 10 minutes.

- At such speed, the test occurs in 10 minutes.

- Second test speed: 10 km/h less than that corresponding to the speed category symbol of the tyre.

- At the 2^nd test speed, the test occurs in 10 minutes.

- Final test speed: corresponding to the speed category symbol of the tyre.

- At the final test speed, the test occurs in 30 minutes.

- Total test duration: 1 hour.
