This International Standard specifies 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;
e)
determining coincidence and flow rate limits.
