标准范围

本文件确立了以下方法:-？用于为自动颗粒计数器准备二次校准悬浮液的验证设备；-？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对给定大小的相同数量的粒子进行计数；-？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中多道过滤器测试中所述的液压过滤器的过滤效率。

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.
