本文件已被宣布为“稳定”，不再接受货币定期审查。用户负责验证参考资料和持续适用性或技术要求。新技术可能存在。本SAE标准规定了用于测量SAE J2130中定义的自行式清扫车和SAE J1116中1、2、4和5类自行式越野作业机外部声级的仪器和程序。本文件不涉及倒车报警器、喇叭或附件等安全装置的操作。通过使用本文件中规定的试验程序获得的声级是可重复的，代表了机器在实际现场操作条件下产生的较高声级范围。 由于现场操作条件的可变性，该数据不拟用于施工现场边界噪声评估。本文件已更改为包含最新适用和相关出版物、测试设备和机器技术。一些技术方面已经澄清。发动机冷却风扇转速要求已更新，以符合全球声音测试标准。

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.This SAE Standard sets forth the instrumentation and procedure to be used in measuring the exterior sound levels for self-propelled sweepers as defined in SAE J2130 and self-propelled off-road work machines in categories 1,2,4, and 5 of SAE J1116.This document does not address the operation of safety devices such as backup alarms, horns, or accessories. The sound levels obtained by using the test procedures set forth in this document are repeatable and are representative of the higher range of sound levels generated by machines under actual field operating conditions. Due to variability of field operating conditions, this data is not intended to be used for construction site boundary noise evaluations.This document has changed to incorporate the latest applicable and related publications, test equipment and machine technology. Some technical aspects have been clarified. Engine cooling fan speed requirements have been updated to coincide with global sound test standards.
