标准摘要
[中文适用范围]： 本文件规定了以下方法： ——验证用于制备自动粒子计数器二次校准悬浮液的设备； ——对自动粒子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，即通过两个在线关联的 APC 对给定尺寸的相同数量的粒子进行计数； ——验证使用或不使用在线稀释的在线颗粒计数系统，例如，测量液压过滤器的过滤效率，如多通道过滤器测试中所述 [外文原描述]： This document establishes methods for: — validating equipment used to prepare secondary calibration suspensions for automatic particle counters; — performing online secondary calibration of automatic particle counters; — matching two or more online particle counters, i.e. to count the same number of particles at a given size by two APCs associated online; — validating 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 multi-pass filter test in ISO 16889.
