Hydraulic fluid power — Determination of the particulate contamination level of a liquid sample by automatic particle counting using the light-extinction principle
Autor: ISO
Código ICS: 23.100.60


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.
