标准范围

本文件规定了一种自动颗粒计数程序，用于使用自动颗粒计数器（APC）确定透明、均匀、单相液体的液压流体瓶样品中存在的颗粒的数量和尺寸，该自动颗粒计数程序基于光消光原理。本文件适用于监测:A）？液压系统中循环流体的清洁度；b）？冲洗操作的进度；c）？支持设备和试验台的清洁程度；d）？包装原液的清洁度。笔记？当超过APC重合误差极限时，可以用悬浮在原始液体中或用相容液体稀释的液体样品中的颗粒进行测量。

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.
