1.1 本试验方法包括在3.5℃下测定润滑脂的氧化诱导时间 兆帕（500 psig），温度在155℃之间 °C和210 °C。 1.2 警告- 研究报告RR:D02-1314中发布的原始数据未按照当前的D2PP进行分析。它还使用了不再制造的仪器，在检查目前使用的仪器时，没有任何原始仪器仍在使用。这种测试方法的新精度仍有待确定。 1.3 以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 1.4 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。 1.5 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 根据本试验方法的条件确定的氧化诱导时间可作为氧化稳定性的指标。 3. 该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 determination of oxidation induction time of lubricating greases subjected to oxygen at 3.5 MPa (500 psig) and temperatures between 155 °C and 210 °C. 1.2 Warning— The original data published in Research Report RR:D02-1314, was not analyzed in accordance the current D2PP. It also used instruments which are no longer manufactured and in a check of currently used instruments, none of the original instruments were still in use. The new precision of this test method is still to be established. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 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 Oxidation induction time, as determined under the conditions of this test method, can be used as an indication of oxidation stability. 3 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.
