Hydraulic fluid power; Calibration of liquid automatic particle-count instruments; Method using Air Cleaner Fine Test Dust contaminant
Описание (англ.):
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 aparticle count work sheet (table 2), lists air cleaner fine test dust with diameters from 1,00
