ISO 11943:2021 Hydraulic fluid power – Online automatic particle-counting systems for liquids – Methods of calibration and validation
CDN $273.00
Description
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.
