1.1 本试验方法（见 注1 )介绍了干式固体膜润滑剂在滑动钢中的耐久性（磨损）寿命和承载能力的测定。 注1: 可参考协调研究委员会（CRC）第419号报告“使用Falex测试仪测量机身粘结固体润滑涂层磨损寿命的研究技术开发”另见SAE航空航天标准AS5272。 1.2 以国际单位制表示的数值将被视为标准值，除非设备使用英寸-磅单位供应，然后将被视为标准值。英寸的公制当量- 在这种情况下，标准正文中给出的磅单位可能是近似值。 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 本试验方法区分了粘结固体润滑剂的磨损寿命和承载能力。如果改变试验条件，磨损寿命可能会改变，粘结固体膜润滑剂的相对额定值可能会不同。

1.1 This test method (see Note 1 ) covers the determination of the endurance (wear) life and load-carrying capacity of dry solid film lubricants in sliding steel-on-steel applications. Note 1: Reference may be made to Coordinating Research Council, Inc. (CRC) Report No. 419, “Development of Research Technique for Measuring Wear Life of Bonded Solid Lubricant Coatings for Airframes, Using the Falex Tester.” See also SAE Aerospace Standard AS5272. 1.2 The values stated in SI units are to be regarded as the standard except where equipment is supplied using inch-pound units and would then be regarded as standard. 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 differentiates between bonded solid lubricants with respect to their wear life and load-carrying capacity. If the test conditions are changed, wear life may change and relative ratings of the bonded solid film lubricants may be different.
