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技术要求 第1部分:一般介绍及分类

[中文适用范围]： 本文件描述了用于在涂装油漆和相关产品之前准备钢基材的金属喷砂清理磨料的分类。 它规定了此类磨料的完整名称所需的特性。 本文件仅适用于以“新”或未使用状态提供的磨料。 它不适用于使用期间或使用后的磨料。 注：虽然本文件是专门为满足钢结构制备的要求而制定的，但指定的属性通常适用于使用喷砂清理技术制备其他材料表面或部件时。 ISO 8504-2 中描述了这些技术。 [外文原描述]： This document describes a classification of 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.
