BS ISO 11171:2016

This standard BS ISO 11171:2016 Hydraulic fluid power. Calibration of automatic particle counters for liquids is classified in these ICS categories:

• 75.120 Hydraulic fluids
• 23.100.60 Filters, seals and contamination of fluids

This International Standard specifies procedures for the following:

1. primary particle-sizing calibration, sensor resolution and counting performance of automatic particle counters (APCs) for liquids 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 truncated test dust;

5. determining coincidence and flow rate limits.
