1.1 本试验方法包括测定润滑脂在高温下分离油的趋势。该试验方法应在100 °C持续30 h，除非润滑脂规格要求其他条件。 1.2 该试验方法可用于任何已加工渗透的润滑脂（试验方法 2017年 )大于220 mm/10（NLGI稠度3或更软）。然而，对于渗透度大于340的润滑脂，没有精度数据 mm/10（比NLGI稠度1号软）。 1.3 以国际单位制表示的值应视为标准值。 术语60 mesh用于描述所使用的金属丝网。该单元在撤回的 第437页 标准，并且没有精确的公制等价物。 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建立适当的安全、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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 当润滑脂分离油时，残留材料的稠度可能会发生变化，这会影响产品按设计运行的能力。使用本程序获得的测试结果不用于预测动态使用条件下润滑脂的油分离趋势。 5.2 本试验方法用于规范和质量控制。

1.1 This test method covers the determination of the tendency of lubricating grease to separate oil at an elevated temperature. This test method shall be conducted at 100 °C for 30 h unless other conditions are required by the grease specification. 1.2 This test method can be used on any grease with a worked penetration (Test Methods D217 ) greater than 220 mm/10 (NLGI Consistency Number 3 or softer). However, no precision data exists for greases with a penetration greater than 340 mm/10 (softer than NLGI Consistency Number 1). 1.3 The values stated in SI units are to be regarded as standard. The term 60 mesh is used to describe the wire mesh used. This unit was described in the withdrawn E437 standard and there is no exact metric equivalent. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its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 When lubricating grease separates oil, the residual material may change in consistency, which can affect the ability of the product to function as designed. Test results obtained with this procedure are not intended to predict oil separation tendencies of grease under dynamic service conditions. 5.2 This test method is used for specifications and quality control.
