A method by which a specified volume of fluid is filtered through a membrane filter of known pore structure. All particulate matter in excess of an 'average size', determined by the membrane characteristics, is retained on its surface.

Visually comparing the test filter with standard patches of known contamination levels determines acceptability for a given fluid.
