This document establishes methods to:

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

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

  3. 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.

  4. 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.
