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

active, Most Current
Organization: ISO
Publication Date: 1 May 2021
Status: active
Page Count: 36
ICS Code (Filters, seals and contamination of fluids): 23.100.60
scope:

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.
