PROCEDURE FOR BENCH TESTS Sample Clauses

PROCEDURE FOR BENCH TESTS. 6.1. Special conditions for carrying out the cycle 6.1.1. The temperature in the room housing the roller-bed shall be between 20/ and 30/C throughout the test and shall approximate as closely as possible to that of the room in which the vehicle has been conditioned for the test. 6.1.2. The vehicle shall be approximately level during the test so as to avoid any abnormal distribution of the fuel. 6.1.3. At the end of the first 40 second idling period (see paragraph 6.2.2.), a current of air of variable speed shall be blown over the vehicle. There will follow two complete cycles during which time no exhaust gas shall be collected. The blower shall incorporate a mechanism controlled by the speed of the bench roller so that, within the range 10-50 km/h, the initial linear wind speed is within 10 per cent of the relative speed of the roller. For roller speeds below 10 km/h the wind speed may be nil. The final section of the blower shall have the following characteristics: Area: at least 0.4 m 2; Height of lower edge above the ground: between 0.15 and 0.20 m; E/ECE/324 Rev.1/Add.39 Regulation No. 40 Annex 4 page 11 Distance from the front of the vehicle: between 0.3 and 0.45 m. 6.1.4. During the test, the speed shall be plotted against time so that the correctness of the cycles performed can be assessed. 6.1.5. The temperatures of the cooling water and the crank-case oil may also be recorded.
