This document specifies procedures for the following:
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;
secondary particle-sizing calibration using suspensions verified with a primary calibrated APC;
establishing acceptable operation and performance limits;
verifying particle sensor performance using a test dust;
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.
