适用范围：This standard specifies an engineering method for measuring the noise emitted by road vehicles of category L (motor bikes) under typical urban traffic conditions, excluding vehicles of category L1 and L2 (mopeds) covered by ISO 9645. The specifications are intended to reproduce the noise levels, which are generated, by the principal noise sources during normal driving in urban traffic. The procedure defined here provides a measure of the sound level from vehicles under controlled and repeatable conditions. The definitions have been carried out according to the needs of vehicle categories. The use of two primary operating conditions a wide open throttle acceleration phase and a constant speed phase guarantee simplicity and the combination was found to be equivalent to the partial throttle and partial power (engine load) actually used. The test method requires an acoustical environment, obtained in an extensive open space.
