Specifies a procedure for the calibration of instruments for particles suspended in liquids when used for the determination of particle size distribution of contaminants encountered in hydraulic fluid power applications. Establishes a uniform and realistic basis for particle sizing and counting. Tabulates materials and equipment and their requirements (table 1), gives a particle count work sheet (table 2), lists air cleaner fine test dust with diameters from 1,00 µm up to and including 100,00 µm (table 3).
