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