1.1 本试验方法包括通过Falex环上块摩擦磨损试验机测定润滑脂的磨损性能。 1.2 以SI单位表示的值应被视为标准值，除非设备使用英寸-磅单位供应，然后将被视为标准值。 1.2.1 例外- 在这种情况下，标准正文中给出的英寸-磅单位的公制当量可能是近似值。 1.3 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。 1.4 本国际标准是根据t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世界贸易组织技术性贸易壁垒委员会。 ======意义和用途====== 5.1 该测试方法用于使用振荡运动区分具有高、中和低磨损预防性能的润滑脂。该方法的用户应自行确定该测试程序的结果是否与现场性能或其他台架测试机器相关。

1.1 This test method covers the determination of wear properties of lubricating greases by means of the Falex block-on-ring friction and wear test machine. 1.2 The values stated in SI units are to be regarded as standard except where equipment is supplied using inch-pound units and would then be regarded as standard. 1.2.1 Exception— The metric equivalents of inch-pound units given in such cases in the body of the standard may be approximate. 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 is used to differentiate between greases having high, medium, and low wear preventive properties using oscillating motion. The user of this method should determine to his own satisfaction whether results of this test procedure correlate with field performance or other bench test machines.
