1.1 本试验方法涵盖滴点高于试验温度的润滑脂氧化稳定性的定量测定。 1.2 本试验方法确定了在试验条件下，在高温下，在密封系统的氧气环境中静态储存时润滑脂的抗氧化性。 1.3 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.4 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。 1.5 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 该测试方法测量由氧化消耗氧气引起的压力净变化和由挥发性氧化副产物形成引起的压力增加。此测试方法可用于质量控制，以指示批次间的一致性。它既不能预测长期储存在容器中的润滑脂的稳定性，也不能预测轴承和电机零件上润滑脂膜的稳定性。 5.2 在本试验方法条件下测定的诱导期可用作氧化稳定性的指标。此测试方法可用于研发、质量控制和规范目的。然而，尚未确定该测试方法的结果与服务性能之间的相关性。

1.1 This test method covers the quantitative determination of the oxidation stability of lubricating greases with a dropping point above the test temperature. 1.2 This test method determines the resistance of lubricating greases to oxidation when stored statically in an oxygen atmosphere in a sealed system at an elevated temperature under conditions of test. 1.3 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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 measures the net change in pressure resulting from consumption of oxygen by oxidation and gain in pressure due to formation of volatile oxidation by-products. This test method may be used for quality control to indicate batch-to-batch uniformity. It predicts neither the stability of greases stored in containers for long periods, nor the stability of films of greases on bearings and motor parts. 5.2 Induction period as determined under the conditions of this test method can be used as an indication of oxidation stability. This test method can be used for research and development, quality control, and specification purposes. However, no correlation has been determined between the results of this test method and service performance.
