This part of ISO 16232 defines methods for determining the size and number of contaminant particles, whichhave been extracted from components and deposited on the surface of a membrane filter, as determined byusing either a light optical microscope (LM) or a scanning electron microscope (SEM). The result of thismeasurement 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 automatically using Image Analysis (IA) techniques if theappropriate equipment is available.
