标准范围

本文件确定了以下方法:-验证用于为自动颗粒计数器准备二次校准悬浮液的设备；-对自动颗粒计数器进行在线二次校准；-匹配两个或多个在线粒子计数器，即通过在线关联的两个APC计算给定大小的相同数量的粒子；-验证在线颗粒计数系统，包括在线稀释和不在线稀释，例如，用于测量ISO 16889中多程过滤器测试中所述的液压过滤器的过滤效率。

This document establishes methods to:— validate equipment used to prepare secondary calibration suspensions for automatic particle counters;— perform online secondary calibration of automatic particle counters;— match two or more online particle counters, i.e. to count the same number of particles at a given size by two APCs associated on line;— validate online particle counting systems with and without online dilution as used, for example, to measure the filtration efficiency of a hydraulic filter as described in the multipass filter test in ISO 16889.
