本SAE标准等同于ISO标准362-1997，除了中详述的差异 附录A ，并包括WP 29在ECE R51修订版1和EEC 92/97和EEC 96/20中采用的修改。 本文件规定了一种工程方法，用于测量所有类型的公路车辆（摩托车除外）在充分利用可用发动机功率的情况下以中间档加速时发出的噪音。 该方法旨在满足实际车辆运行条件下结果的简单性和再现性的要求。 测量涉及车辆的操作条件，该操作条件给出与城市驾驶一致的最高噪声水平，并且导致可再现的噪声排放。因此，规定了在规定的发动机或车速下进行全油门加速试验。该测试方法要求声学环境只能在广阔的开放空间中获得。通常可以为以下情况提供此类条件: 一个 制造阶段的测量 b 在官方检测站进行测量 测量必须在符合本文件规定要求的声学环境中进行。应该注意的是，随机选择的车辆很少能在理想的声学环境中进行抽查。如果必须在不满足本文件规定要求的声学环境中在道路上进行测量，则应认识到所获得的结果可能明显偏离使用规定条件获得的结果。 通过该方法获得的结果给出了在规定的测试条件下发出的噪声的客观测量。然而，有必要考虑这样一个事实，即对不同类别机动车辆的恼人程度的主观评估并不简单地与声级计的指示相关。摩托车包含在其他SAE文件中，这些文件规定了更能代表实际使用的操作模式。

This SAE Standard is equivalent to ISO Standard 362 - 1997 except for the differences detailed in Appendix A , and includes the modifications adopted by WP 29 in ECE R51 Revision 1 and EEC 92/97 and EEC 96/20. This document specifies an engineering method for measuring the noise emitted by accelerating highway vehicles of all types (except motorcycles) in intermediate gears with full utilization of the available engine power. The method is designed to meet the requirements of simplicity and reproducibility of results under realistic vehicle operating conditions. Measurements relate to operating conditions of the vehicle which give the highest noise level consistent with urban driving and which lead to reproducible noise emissions. Therefore, an acceleration test at full throttle from a stated engine or vehicle speed is specified. The test method calls for an acoustical environment which can only be obtained in an extensive open space. Such conditions can usually be provided for: a Measurements at the manufacturing stage b Measurements at official testing stations Measurements must be carried out in an acoustical environment which fulfill the requirements stated in this document. It should be noted that spot checking of vehicles chosen at random can rarely be made in an ideal acoustical environment. If measurements have to be carried out on the road in an acoustical environment which does not fulfill the requirements stated in this document, it should be recognized that the results obtained may deviate appreciably from the results obtained using the specified conditions. The results obtained by this method give an objective measure of the noise emitted under prescribed conditions of test. However, it is necessary to consider the fact that the subjective appraisal of the annoyance of different classes of motor vehicles is not simply related to the indications of a sound level meter. The motorcycles are covered in other SAE documents that prescribe an operating mode that is more representative of actual use.
