Hydraulic fluid power — Calibration of automatic particle counters for liquids ISO 11171:2016

Publication date:   Oct 5, 2016

Scope

ISO 11171:2016 specifies procedures for the following:
a) primary particle-sizing calibration, sensor resolution and counting performance of automatic particle counters (APCs) for liquids capable of analysing bottle samples;
b) secondary particle-sizing calibration using suspensions verified with a primary calibrated APC;
c) establishing acceptable operation and performance limits;
d) verifying particle sensor performance using a truncated test dust;
e) determining coincidence and flow rate limits.
