Describes procedures for: 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; and e) determining coincidence and flow rate limits.

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