涂料和相关产品使用前钢衬底的制备.非金属喷砂清理磨料的试验方法.第8部分:水溶性氯化物的现场测定

[中文适用范围]： 本文件规定了测定非金属喷砂清理磨料中水溶性氯化物的现场方法。 该现场方法以套件形式提供，其中包含所有组件和预测量的提取溶液。 本文件与 ISO 11127-7 的不同之处在于，使用等体积的磨料样品和提取溶液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）的重量与体积比来从磨料中提取可溶性盐。 与 ISO 11127-7 相比，它适合在现场使用，而 ISO 11127-7 非常适合在实验室中使用。 [外文原描述]： 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.
