Hydraulic fluid power -- Calibration of automatic particle counters for liquids
This International Standard contains procedures for:
- primary particle-sizing, sensor resolution and counting performance;
- secondary particle-sizing calibration using suspensions prepared with NIST reference materials;
- establishing acceptable operation and performance limits;
- verifying particle sensor performance using a truncated test dust;
- determining coincidence and flow rate limits.
