Abstract

This document specifies an automatic particle counting procedure for determining the number and sizes of particles present in hydraulic-fluid bottle samples of clear, homogeneous, single-phase liquids using an automatic particle counter (APC) that works on the light-extinction principle. This document is applicable to the monitoring of: a) the cleanliness level of fluids circulating in hydraulic systems; b) the progress of a flushing operation; c) the cleanliness level of support equipment and test rigs; d) the cleanliness level of packaged stock fluid. NOTE Measurements can be made with particles suspended in the original liquid or in a sample of the liquid diluted with a compatible liquid when APC coincidence error limits are exceeded.
