本文件规定了非金属喷砂清理磨料表观密度的测定方法。 本文件是ISO 11127系列的一部分，涉及喷砂清理用非金属磨料的取样和测试。 ISO 11126系列中包含了非金属磨料的类型及其要求。 ISO 11126和ISO 11127系列已被起草为一套关于非金属喷砂清理磨料的一致国际标准。附件A中给出了两个系列所有部分的信息。

This document specifies a method for the determination of the apparent density of non-metallic blast-cleaning abrasives. This document is a part of the ISO 11127 series dealing with the sampling and testing of non-metallic abrasives for blast-cleaning. The types of non-metallic abrasive and requirements for each are contained in the ISO 11126 series. The ISO 11126 and ISO 11127 series have been drafted as a coherent set of International Standards on non-metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex A.
