本文件描述了非金属喷砂清理磨料的分类，用于在涂覆涂料和相关产品之前制备钢基体。 它规定了此类磨料完整命名所需的特性。 本文件仅适用于以“新”或未使用状态提供的磨料。它不适用于磨料使用期间或之后。 注:尽管本文件是专门为满足钢结构制备要求而编制的，但规定的性能通常适用于使用喷砂处理其他材料表面或部件时- 清洁技术。ISO 8504-2中描述了这些技术。

This document describes a classification of non-metallic blast-cleaning abrasives for the preparation of steel substrates before application of paints and related products. It specifies the characteristics which are required for the complete designation of such abrasives. This document applies to abrasives supplied in the "new" or unused condition only. It does not apply to abrasives either during or after use. NOTE Although this document has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504？2.
