1.1本指南描述了一种用于测量液体氧化或热稳定性的仪器，方法是在空气、氧气、氮气或其他气体存在的情况下，以1.5至13升/小时的流速，或在没有气流的情况下，将其置于50至375°C的温度范围内。可在存在或不存在水或可溶性或不溶性催化剂的情况下测量稳定性。释放的气体可以逸出、冷凝并收集，或冷凝并返回试验室。 1.2本标准无意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。

1.1 This guide describes an apparatus used to measure the oxidation or thermal stability of liquids by subjecting them to temperatures in the range from 50 to 375°C in the presence of air, oxygen, nitrogen, or other gases at flow rates of 1.5 to 13 L/h, or in the absence of gas flow. Stability may be measured in the presence or absence of water or soluble or insoluble catalysts. Gases evolved may be allowed to escape, condensed and collected, or condensed and returned to the test cell. 1.2 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.
