本文件规定了为喷砂清理工艺提供的镍渣磨料的要求。它规定了表观密度、莫氏硬度、水分含量、水萃取物和水溶性氯化物的粒径范围和值。 本文件中规定的要求仅适用于在“新”条件下提供的磨料。它们不适用于磨料使用期间或之后。 ISO 11127各部分给出了非金属喷砂清理磨料的试验方法。 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。

This document specifies requirements for nickel 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.
