1.1 本试验方法涵盖了使用切削保护性能（CPP）测试仪测量材料安装在心轴上并在规定载荷下承受切削刃时的切削阻力。 1.1.1 该程序不适用于高孔隙率材料，这些材料在切割前允许切割边缘与安装表面接触。 1.1.2 测试仪器在测试厚度大于3 mm或具有高摩擦系数的材料（如弹性体）时可能存在局限性。 1.2 以国际单位制或英寸表示的数值- 磅单位应单独视为标准单位。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本试验方法评估了材料在规定载荷下暴露于切割边缘时的抗切割性。从该试验方法获得的数据可用于比较不同材料的抗切割性。 5.2 本试验方法仅解决与材料表面光滑锋利边缘的切割作用有关的切割危险范围。它不代表材料可能遭受的任何其他切割危险，例如锯齿边缘、锯片或电动切割工具。它也不能代表穿刺、撕裂或其他织物失效模式。

1.1 This test method covers the measurement of the cut resistance of a material when mounted on a mandrel and subjected to a cutting edge under a specified load using the Cut Protection Performance (CPP) Tester. 1.1.1 This procedure is not valid for high-porosity materials which allow cutting edge contact with the mounting surface prior to cutting. 1.1.2 Test apparatus may have limitations in testing materials with a thickness greater than 3 mm or having a high frictional coefficient such as elastomers. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the 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 method assesses the cut resistance of a material when exposed to a cutting edge under specified loads. Data obtained from this test method can be used to compare the cut resistance of different materials. 5.2 This test method only addresses that range of cutting hazards that are related to a cutting action by a smooth, sharp edge across the surface of the material. It is not representative of any other cutting hazard to which the material may be subjected such as serrated edges, saw blades, or motorized cutting tools. Nor is it representative of puncture, tear, or other modes of fabric failure.
