标准范围

本文件规定了非金属喷砂清理磨料中水溶性氯化物的现场测定方法。该现场方法作为试剂盒提供，包括所有成分和预测量的提取溶液。本文件与ISO 11127-7的不同之处在于，使用等量的磨料和萃取溶液样品来测定磨料中的氯化物含量。相比之下，ISO 11127-7使用磨料与溶剂（去离子水）的重量体积比从磨料中提取可溶性盐。与ISO 11127-7相比，ISO 11127-7非常适合在实验室中使用。

This document specifies a field method for the determination of water-soluble chlorides in non-metallic blast-cleaning abrasives. This field method is provided as a kit with all components and premeasured extraction solution.This document differs from ISO 11127-7 in that equal volumes of the sample of abrasive and extraction solution are used for the determination of chloride level in the abrasive. In comparison, ISO 11127-7 uses a weight to volume ratio of abrasive to solvent (deionized water) to extract soluble salts from the abrasive. It is intended for use in the field as compared to ISO 11127-7, which is well suited for use in the laboratory.
