ISO 8528-9:2017描述了在本文件所述测量点测量和评估发电机组外部机械振动行为的程序。 它适用于RIC发动机驱动的交流发电机组，用于刚性和/或弹性安装的固定和移动安装。它适用于陆地和海洋用途，不包括飞机上使用的发电机组或用于推动陆地车辆和机车的发电机组。 对于某些特定应用（基本医院用品、高层建筑等），可能需要补充要求。本文件的规定旨在被视为此类应用的基础。 对于由其他往复式原动机（如污水燃气发动机、蒸汽发动机）驱动的发电机组，本文件的规定将被视为此类应用的基础。

ISO 8528-9:2017 describes a procedure for measuring and evaluating the external mechanical vibration behaviour of generating sets at the measuring points stated in this document. It applies to RIC engine driven a.c. generating sets for fixed and mobile installations with rigid and/or resilient mountings. It is applicable for land and marine use, excluding generating sets used on aircraft or those used to propel land vehicles and locomotives. For some specific applications (essential hospital supplies, high rise buildings, etc.) supplementary requirements may be necessary. The provisions of this document are intended to be regarded as a basis for such applications. For generating sets driven by other reciprocating-type prime movers (e.g. sewage gas engines, steam engines), the provisions of this document are intended to be regarded as a basis for such applications.
