Hydraulic fluid power — Online automatic particle-counting systems for liquids — Methods of calibration and validation

This document establishes methods for:

—?? validating equipment used to prepare secondary calibration suspensions for automatic particle counters;

—??? performing online secondary calibration of automatic particle counters;

—??? matching two or more online particle counters, i.e. to count the same number of particles at a given size by two APCs associated online;

—??? validating online particle counting systems with and without online dilution as used, for example, to measure the filtration efficiency of a hydraulic filter as described in the multi-pass filter test in ISO 16889.
