标准范围

ISO 362-1:2007规定了在典型城市交通条件下测量M和N类道路车辆发出的噪声的工程方法。它不包括ISO 9645所涵盖的L1和L2类车辆，以及ISO 362-2所涵盖的L3、L4和L5类车辆。本规范旨在重现城市交通正常行驶期间主要噪声源产生的噪声水平。该方法旨在满足简单性要求，只要它们与车辆运行条件下结果的再现性一致。该测试方法需要一个只有在广阔的开放空间中才能获得的声学环境。此类条件通常用于车辆的型式认证测量、制造阶段的测量和官方测试站的测量。

ISO 362-1:2007 specifies an engineering method for measuring the noise emitted by road vehicles of categories M and N under typical urban traffic conditions. It excludes vehicles of category L1 and L2, which are covered by ISO 9645, and vehicles of category L3, L4 and L5 covered by ISO 362-2.The specifications are intended to reproduce the level of noise generated by the principal noise sources during normal driving in urban traffic.The method is designed to meet the requirements of simplicity as far as they are consistent with reproducibility of results under the operating conditions of the vehicle.The test method requires an acoustical environment that is only obtained in an extensive open space. Such conditions are usually provided for type approval measurements of a vehicle, measurements at the manufacturing stage, and measurements at official testing stations.
