1.1 本试验方法涵盖了测定塑料抗滑动磨损性的实验室程序。该测试使用块对环摩擦磨损测试机，根据塑料对金属或其他固体的滑动磨损特性对塑料进行分级。 1.2 这个测试的一个重要特性是它非常灵活。任何可以制造或应用于块和环的材料都可以进行测试。因此，潜在的材料组合是无穷无尽的。此外，根据需要，可以在不同的气体环境和升高的温度下进行测试，以模拟使用条件。 1.3 磨损试验结果以块和环的体积损失（单位:立方毫米）表示。耐磨性较高的材料的体积损失较低。 1.4 以国际单位制表示的数值应视为标准。 括号中给出的值仅供参考。 1.5 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。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 该测试方法在针对服务应用程序的任何总体测量程序中的重要性将取决于测试条件与服务应用程序条件的相对匹配。 5.2 本试验方法规定了使用累积体积损失测定塑料滑动耐磨性的试验程序和计算和报告数据的方法。 5.3 本试验的预期用途是对塑料的抗滑动磨损性进行粗略筛选。

1.1 This test method covers laboratory procedures for determining the resistance of plastics to sliding wear. The test utilizes a block-on-ring friction and wear testing machine to rank plastics according to their sliding wear characteristics against metals or other solids. 1.2 An important attribute of this test is that it is very flexible. Any material that can be fabricated into, or applied to, blocks and rings can be tested. Thus, the potential materials combinations are endless. In addition, the test can be run with different gaseous atmospheres and elevated temperatures, as desired, to simulate service conditions. 1.3 Wear test results are reported as the volume loss in cubic millimetres for the block and ring. Materials of higher wear resistance will have lower volume loss. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 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. 1.6 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 The significance of this test method in any overall measurement program directed toward a service application will depend on the relative match of test conditions to the conditions of the service application. 5.2 This test method prescribes the test procedure and method of calculating and reporting data for determining the sliding wear resistance of plastics, using cumulative volume loss. 5.3 The intended use of this test is for coarse screening of plastics in terms of their resistance to sliding wear.
