This document specifies procedures for the following:
a)   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;
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 test dust;
e)   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.
