time of type approval, the means to protect against simple unauthorised modification of the operation of the failure warning signal chosen by the manufacturer shall be confidentially outlined.

              Alternatively, this protection requirement is fulfilled when a secondary means of checking the correct operational status of the AEBS is available.

6. Test procedure
              6.1. Test Conditions

              6.1.1. The test shall be performed on a flat. dry concrete or asphalt surface affording good adhesion.

              6.1.1.1. The road test surface shall have a nominal[4] peak braking coefficient (PBC) of 0.9. unless otherwise specified. when measured using either:

              6.1.1.2. The American Society for Testing and Materials (ASTM) E1136 standard reference test tyre. in accordance with ASTM Method E1337‑90. at a speed of 40 mph; or

              6.1.1.3. The k-test method specified in Appendix 2 to Annex 6 of Regulation No. 13-H.

              6.1.1.4. The test surface has a consistent slope between level and 1 per cent.

              6.1.2.  The ambient temperature shall be between 0°C and 45°C.

              6.1.3.  The horizontal visibility range shall allow the target to be observed throughout the test.

              6.1.4  The tests shall be performed when there is no wind liable to affect the results.

              6.1.5. Natural ambient illumination must be homogeneous in the test area and in excess of 1000 lux in the case of car to car scenario as stipulated in paragraph 5.2.1. and of 2000 lux in the case of car to pedestrian scenario as stipulated in paragraph 5.2.2. It should be ensured that testing is not performed whilst driving towards, or away from the sun at a low angle.

              6.2.  Vehicle Conditions

              6.2.1. Test mass

               The vehicle shall be tested:

                  (a) At the mass in running order with an additional mass of maximum 125 kg where this additional mass includes the measuring equipment and a possible second person who is responsible for noting the results in order to demonstrate compliance with the requirements referring to the mass in running order, and

                  (b) At the maximum mass
              The load distribution shall be according to the manufacturer's recommendation and be annexed to the test report. No alteration shall be made once the test procedure has begun.

              During the series of test runs, the fuel level may decrease but shall never fall below 50 %.

              6.2.2. Pre-Test Conditioning

              6.2.2.1. If requested by the vehicle manufacturer:

                  (a) The vehicle can be driven a maximum of 100 km on a mixture of urban and rural roads with other traffic and roadside furniture to initialise the sensor system.

                  (b) The vehicle can undergo a sequence of brake activations in order to ensure the service brake system is bedded in prior to the test.

                  (c) The average temperature of the service brakes on the hottest axle of
