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6部分:外来杂质测定

[中文适用范围]： 本文件规定了金属喷砂清理磨料中异物测定的试验方法。 测试的目的是确定磨料被异物污染的程度。 异物（例如氧化物和残留冶金渣）的水平通过磁选来确定。 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 ISO 11124 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 foreign matter in metallic blast-cleaning abrasives. The purpose of the test is to establish the level to which the abrasive is contaminated by foreign matter. The level of foreign matter, e.g. oxides and residual metallurgical slag, is determined by magnetic separation. 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 on 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.
