BS ISO 11171:2020 - Hydraulic fluid power. Calibration of automatic particle counters for liquids

BS ISO 11171:2020

Hydraulic fluid power. Calibration of automatic particle counters for liquids

Status : Current   Published : November 2020



This document specifies procedures for the following:

  1. primary particle-sizing calibration for particle sizes 1 µm(c) and larger, sensor resolution and counting performance of liquid automatic particle counters that are capable of analysing bottle samples;

  2. secondary particle-sizing calibration using suspensions verified with a primary calibrated APC;

  3. establishing acceptable operation and performance limits;

  4. verifying particle sensor performance using a test dust;

  5. determining coincidence and flow rate limits.

This document is applicable for use with hydraulic fluids, aviation and diesel fuels, engine oil and other petroleum-based fluids. This document is not applicable to particle-sizing calibration using NIST SRM 2806b primary calibration suspensions.
