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4部分:表观密度测定

[中文适用范围]： 本文件规定了测定金属喷砂清理磨料表观密度的试验方法。 测试的目的是确定金属磨料的健全性。 显着水平的内部收缩或空心颗粒将降低表观密度。 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 the apparent density of metallic blast-cleaning abrasives. The purpose of the test is to establish the soundness of the metallic abrasive. Significant levels of internal shrinkage or hollow particles will reduce the apparent density. 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.
