标准范围

本文件规定了为喷砂清理工艺提供的12级冷铁磨粒磨料的要求。它指定了颗粒大小的范围，以及相应的等级名称。规定了硬度、密度、缺陷/结构要求和化学成分的数值。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 11125各部分给出了金属喷砂清理磨料的试验方法。冷硬铁砂磨料用于静态和现场喷砂设备。在有回收和再利用研磨剂的设施的情况下，通常会选择研磨剂。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 12 grades of chilled-iron grit abrasives, as supplied for blast-cleaning processes. It specifies ranges of particle sizes, together with corresponding grade designations. Values are specified for hardness, density, defect/structural requirements and chemical composition.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 metallic blast-cleaning abrasives are given in the various parts of ISO 11125.Chilled-iron grit abrasives are used in both static and site blasting equipment. They are most often selected where a facility exists for recovery and re-use of the abrasive.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.
