本文件描述了光散射液体载体的校准和验证方法 颗粒计数器（LSLPC），用于测量颗粒的大小和颗粒数浓度 悬浮在液体中的颗粒。本文件中描述的光散射方法是基于单个 粒子测量。通过该方法测量的颗粒的典型尺寸范围在0.1µm之间 粒径为10µm。 本方法适用于用于评估纯水和水的清洁度的仪器 化学品，以及测量各种液体中颗粒的数量和尺寸分布。 使用LSLPC测量的颗粒大小取决于颗粒和介质的折射率； 因此，测得的颗粒大小相当于纯水中的校准颗粒。 交叉引用:ISO/IEC指南99:2007 ISO 9276-1ISO/IEC 17025ISO/IEC指南98-3JIS B 9925:2010购买本文件时可获得的所有当前修订版均包含在购买本文件中。

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.Cross References:ISO/IEC Guide 99:2007ISO 9276-1ISO/IEC 17025ISO/IEC Guide 98-3JIS B 9925:2010All current amendments available at time of purchase are included with the purchase of this document.
