涂装油漆和有关产品前钢材预处理 喷射清理用金属磨料的试验方法 第7部分:含水量测定

[中文适用范围]： 本文件规定了测定金属喷砂清理磨料中游离水分含量的测试方法。 它是通过测量加热时损失的质量来确定的。 这是 ISO 11125 中涉及喷砂清理金属磨料取样和测试的众多部分之一。 金属磨料的类型及其要求包含在金属喷砂清理磨料的各个部分中。 附录 A 中给出了两个系列所有部分的信息。 [外文原描述]： This document specifies a test method for the determination of the level of free moisture present in metallic blast-cleaning abrasives. It is determined by measuring the mass lost on heating. This is one of a number of parts of ISO 11125 dealing with the sampling and testing of metallic abrasives for blast-cleaning. The types of metallic abrasive and requirements for each are contained in the various parts of ISO 11124. The ISO 11124 and ISO 11125 series have been drafted as a coherent set of International Standards on metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex A.
