标准摘要
[中文适用范围]： 本文件描述了光散射液载颗粒计数器（LSLPC）的校准和验证方法，用于测量悬浮在液体中的颗粒的尺寸和颗粒数浓度。 本文件中描述的光散射方法基于单粒子测量。 通过此方法测量的颗粒的典型尺寸范围为 0.1 µm 至 10 µm。 该方法适用于评价纯水和化学品清洁度以及测量各种液体中颗粒数量和粒径分布的仪器。 使用LSLPC测量的颗粒尺寸取决于颗粒和介质的折射率；因此，测量的颗粒尺寸相当于纯水中的校准颗粒尺寸。 以下情况均属于本文件的范围： ——尺寸设置错误； ——计数效率； ——尺寸分辨率； ——错误计数； ——最大颗粒数浓度； ——采样流量误差； ——采样时间误差； ——取样体积误差； ——校准间隔； ——报告测试和校准的结果。 [外文原描述]： This document describes a calibration and verification method for a light scattering liquid-borne particle counter (LSLPC), which is used to measure the size and particle number concentration of particles suspended in liquid. The light scattering method described in this document is based on single particle measurements. The typical size range of particles measured by this method is between 0,1 µm and 10 µm in particle size. The method is applicable to instruments used for the evaluation of the cleanliness of pure water and chemicals, as well as the measurement of number and size distribution of particles in various liquids. The measured particle size using the LSLPC depends on the refractive index of particles and medium; therefore, the measured particle size is equivalent to the calibration particles in pure water. The following are within the scope of this document: — size setting error; — counting efficiency; — size resolution; — false count; — maximum particle number concentration; — sampling flow rate error; — sampling time error; — sampling volume error; — calibration interval; — reporting results from test and calibration.
