1.1 本试验方法包括对刚性工程材料在与氧化铝抛光带摩擦时的耐磨性进行分级。虽然大多数固体都可以进行测试，但这种测试方法解决了其在金属和金属涂层上的应用。 1.2 以国际单位制表示的值应视为标准值。本标准不包括其他测量单位。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 该测试可用于筛选工具中使用的材料，这些材料会受到加工、加工或成形材料的磨损。它已用于筛选冲压模具的工具钢、土方机械的硬质表面和耐磨涂层。该试验装置的制造和使用比试验方法中使用的装置更简单 第132页 磨损试验，与本试验类似，使用固定的磨料反表面来磨损试验材料。 5.2 一小时试验适用于比硬化钢（67 HRC）更软的金属和材料，但也适用于更硬的材料。

1.1 This test method covers ranking rigid engineering materials for abrasion resistance in rubbing against aluminum oxide abrasive finishing tape. Though most solids can be tested, this test method addresses its use for metals, and coatings applied to metals. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test is useful for screening materials for use in tools that are subjected to abrasion from the material that is being machined, worked, or formed. It has been used to screen tool steels for punch press dies, hard-facings for earth-moving machinery, and wear coatings. This test apparatus is simpler to build and use than those used in the Test Method G132 abrasion test which, like this test, uses a fixed abrasive counterface to abrade a test material. 5.2 The one-hour test is intended for metals and materials that are softer than hardened steel (67 HRC), but may be applied to harder materials.
