1.1本试验方法包括测定润滑油在3.5 MPa（500 psig）和130至210°C温度下的氧化诱导时间。 1.2以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.2.1 例外情况- 压力测量以MPa为单位，括号中提供的psig仅供参考。 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 4.1根据本试验方法条件确定的氧化诱导时间可作为氧化稳定性的指标。 2. 该测试方法比其他油氧化测试更快，并且需要非常少量的样品。它可用于研发、质量控制和规范目的。然而，该测试方法的结果与服务性能之间没有相关性。

1.1 This test method covers the determination of oxidation induction time of lubricating oils subjected to oxygen at 3.5 MPa (500 psig) and temperatures between 130 and 210°C. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.2.1 Exception— Pressure measurement appears in MPa with psig provided in parentheses for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 4.1 Oxidation induction time, as determined under the conditions of this test method, may be used as an indication of oxidation stability. 2 This test method is faster than other oil oxidation tests and requires a very small amount of sample. It may be used for research and development, quality control, and specification purposes. However, no correlation has been established between the results of this test method and service performance.
