适用范围：This International Standard specifies an automatic particle counting procedure for determining the number andsizes of particles present in hydraulic-fluid bottle samples of clear, homogeneous, single-phase liquids usingan automatic particle counter (APC) that works on the light-extinction principle.This International Standard is applicable to the monitoring ofa) 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.NOTE 1 Measurements can be made with particles suspended in the original liquid or in a sample of the liquid dilutedwith a compatible liquid to reduce coincidence error.NOTE 2 The presence of a fluid interface obstructs the light beam and gives false signals.
