1 Scope

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:

  1. the cleanliness level of fluids circulating in hydraulic systems;

  2. the progress of a flushing operation;

  3. the cleanliness level of support equipment and test rigs;

  4. 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 APCcoincidence error limits are exceeded.
