1.1本试验方法包括测定润滑脂在高温下分离油的趋势。除非润滑脂规范要求其他条件，否则本试验方法应在100°C下进行30小时。 1.2本试验方法不适用于渗透性（试验方法D 217）大于340（软于NLGI 1级）的润滑脂。 1.3以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 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规程，并确定监管限制的适用性。 ====意义和用途====== 当润滑脂分离油时，残留材料的稠度发生变化，这可能会影响产品按设计工作的能力。通过该程序获得的测试结果旨在与35 lb桶润滑脂在储存期间发生的油分离相关。其目的不是预测动态使用条件下润滑脂的油分离趋势。 笔记 1-35磅桶中的油分离与结果之间没有定量关系。 本试验方法用于规范和质量控制。 笔记 2-尚未开发数据来比较本试验方法和试验方法D 1742之间的结果 .

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 is not suitable for greases having a penetration (Test Methods D 217) greater than 340 (softer than NLGI No. 1 grade). 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== When a lubricating grease separates oil, the residual material changes in consistency, which can affect the ability of the product to function as designed. Test results obtained with this procedure are intended to correlate with oil separation that occurs in 35-lb pails of grease during storage. They are not intended to predict oil separation tendencies of grease under dynamic service conditions. Note 1—No quantitative relationship between results and oil separation in 35-lb pails has been developed. This test method is used for specifications and quality control. Note 2—No data have been developed to compare results between this test method and Test Method D 1742 .
