石油产品和润滑剂. 润滑脂抗水淋特性的测定

[中文适用范围]： 本文件规定了一种评估润滑脂在 38°C 或 79°C 温度下在指定实验室测试条件下对轴承水冲刷的抵抗力的方法。该测试方法估计润滑脂在指定条件下对滚珠轴承冲刷的抵抗力。目前尚未与现场服务建立正式关联。本文件用于开发和规范目的。注意：就本文件而言，术语“% (m/m)”用于表示质量分数。 [外文原描述]： This document specifies a method for evaluating the resistance of a lubricating grease to washout by water from a bearing, when tested at 38 °C or 79 °C under specified laboratory test conditions. This test method estimates the resistance of greases to washout from ball bearings under specified conditions. No formal correlation with field service has been established so far. This document is used for development and specification purposes. NOTE For the purposes of this document, the term “% ( m / m )” is used to represent the mass fraction.
