Hydraulic fluid power. Calibration of automatic-count instruments for particles suspended in liquids. Method using classified AC fine test dust contaminant

DS/ISO 4402-1989 发布历史

This International Standard specifies a procedure for the calibration of automatic counting instruments for particles suspended in liquids when used for the determination of particle size distribution of contaminants encountered in hydraulic fluid power applications. It also establishes a uniform and realistic basis for particle sizing and counting. NOTE — It is assumed that users of this procedure are competent in the operation of their particular particle-counter and that proper sample-handling techniques will be used throughout the procedure. Sample-handling techniques which allow particle settling, erroneous suspension concentration, etc, can result in incorrect calibration.
