标准摘要
[中文适用范围]： 本文件规定了用于喷砂清理过程的煤炉矿渣磨料的要求。 它规定了颗粒尺寸的范围以及表观密度、莫氏硬度、水分含量、水提取物和水溶性氯化物的电导率。 本文件中规定的要求仅适用于以“新”状态提供的磨料。 它们不适用于使用期间或使用后的磨料。 ISO 11127 的各个部分给出了非金属喷砂清理磨料的测试方法。 注：虽然本文件是专门为满足钢结构制备的要求而制定的，但指定的性能通常适用于制备其他材料表面时使用或部件，使用喷砂清理技术。 ISO 8504-2 中描述了这些技术。 [外文原描述]： This document specifies requirements for coal furnace slag abrasives, as supplied for blast-cleaning processes. It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides. The requirements specified in this document apply to abrasives supplied in the "new" condition only. They do not apply to abrasives either during or after use. Test methods for non-metallic blast-cleaning abrasives are given in the various parts of ISO 11127. 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.
