本文件规定了测定金属喷砂清理磨料中异物的试验方法。 试验的目的是确定磨料被异物污染的程度。杂质（如氧化物和残余冶金渣）的含量由磁选确定。 这是ISO 11125中涉及喷砂清理用金属磨料取样和测试的部分之一。 ISO 11124的各个部分包含了金属磨料的类型和要求。 ISO 11124和ISO 11125系列已被起草为一套关于金属喷砂的连贯国际标准- 清洁磨料。附件A中给出了两个系列所有部分的信息。

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.
