ISO 8525:2008参考ISO 230-5，描述了测定金属切割机和相关辅助设备发出的空气噪声的可再现试验方法所需的机械和声学规范。目的是便于获得类似机器噪声排放的可比测试结果。测试结果可用于比较、验收、维护或任何其他目的。 ISO 8525:2008特别规定了测量金属切割机（不包括任何切割过程）发出的噪声的操作条件。这些操作条件对于确定指定位置处的声功率级和发射声压级是完全相同的。 ISO 8525:2008适用于各种车床和各种铣床。

ISO 8525:2008 describes, with reference to ISO 230-5, the mechanical and acoustical specifications necessary for a reproducible test method for the determination of airborne noise emitted by metal-cutting machines and related auxiliary equipment. The purpose is to facilitate the obtention of comparable test results on the noise emission of similar machines. The results of the tests can be used for comparison, acceptance, maintenance or any other purpose. ISO 8525:2008 specifies, in particular, operating conditions for the measurement of noise emitted by metal cutting machines excluding any cutting process. These operating conditions are strictly the same for the determination of both sound power levels and emission sound pressure levels at specified positions. ISO 8525:2008 applies to all kinds of turning machines and all kinds of milling machines.
