Organization: ISO
Publication Date: 22 June 2020
Status: active
Page Count: 35
ICS Code (Filters, seals and contamination of fluids): 23.100.60
scope:

This document establishes methods to:

- validate equipment used to prepare secondary calibration suspensions for automatic particle counters;

- perform on-line secondary calibration of automatic particle counters;

- match two or more on-line particle counters (i.e. to make count the same number of particles at a given size by two APCs associated on line.

- validate on-line particle counting systems with and without on-line dilution as used, for example, to measure the filtration efficiency of a hydraulic filter as described in the multipass filter test ISO 16889.
