ISO 16232-7:2007定义了通过光学显微镜（LM）或扫描电子显微镜（SEM）测定从组件中提取并沉积在膜过滤器表面的污染物颗粒大小和数量的方法。该测量的结果是膜过滤器上的粒度分布。由于零件和组件的功能可能会因单个或几个关键颗粒的存在而受损，因此必须对整个膜过滤器表面进行完整的分析。如果有合适的设备，可以使用图像分析（IA）技术手动或全自动执行这些分析。

ISO 16232-7:2007 defines methods for determining the size and number of contaminant particles, which have been extracted from components and deposited on the surface of a membrane filter, as determined by using either a light optical microscope (LM) or a scanning electron microscope (SEM). The result of this measurement is the particle size distribution on the membrane filter.As the function of parts and components can be impaired by the presence of a single or a few critical particles, a complete analysis of the total membrane filter surface is essential.These analyses can be performed either manually or fully automatically using Image Analysis (IA) techniques if the appropriate equipment is available.
