1.1 本试验方法包括使用铁姆肯极压测试仪测定润滑液的承载能力。 注1: 本试验方法适用于测试粘度小于约5000的流体 cSt（5000 毫米 2. /s） 40岁时 °C。对于粘度较高的测试流体，请参阅 附注5 在里面 9.1 . 1.2 以国际单位制表示的数值应视为标准值。由于本试验方法中使用的设备仅以英寸-磅为单位，因此在提及设备和试样时省略了国际单位制。 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。 具体警告声明见 7.1 , 7.2 , 8.1 , 8.2 , 9.4 和 9.9 . 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 本试验方法广泛用于确定规范中的极端压力特性。在确定规范极限时，用户应谨慎考虑此处的精度和偏差声明。

1.1 This test method covers the determination of the load-carrying capacity of lubricating fluids by means of the Timken Extreme Pressure Tester. Note 1: This test method is suitable for testing fluids having a viscosity of less than about 5000 cSt (5000 mm 2 /s) at 40 °C. For testing fluids having a higher viscosity, refer to Note 5 in 9.1 . 1.2 The values stated in SI units are to be regarded as standard. Because the equipment used in this test method is available only in inch-pound units, SI units are omitted when referring to the equipment and the test specimens. 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. Specific warning statements are given in 7.1 , 7.2 , 8.1 , 8.2 , 9.4 , and 9.9 . 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 widely for the determination of extreme pressure properties for specification purposes. Users are cautioned to carefully consider the precision and bias statements herein when establishing specification limits.
