1.1 本试验方法涵盖了在规定的实验室条件下，在38°C和79°C（100°F和175°F）下进行试验时，润滑脂对轴承水冲刷的抵抗力的评价。它不应被视为等同于服务评估测试。使用研究报告中NLGI 3至0级的润滑脂测定精密度和偏差（见第节 11 ). 1.2 本试验方法可能不适用于某些含有高挥发性成分的润滑脂。该测试方法未尝试考虑样品蒸发。用户有责任确定样品的蒸发是否是所需干燥温度下质量损失的重要因素。 1.3 以SI单位表示的值将被视为标准值。SI单位后括号中给出的值仅供参考，不被视为标准值。1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。 具体警告语句，请参见 7.3 . 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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 5.1 本试验方法评估润滑脂在试验条件下对滚珠轴承水冲刷的抵抗力。未建立与现场服务的相关性。

1.1 This test method covers the evaluation of the resistance of a lubricating grease to washout by water from a bearing, when tested at 38 °C and 79 °C (100 °F and 175 °F) under the prescribed laboratory conditions. It is not to be considered the equivalent of service evaluation tests. Precision and bias was determined using grease ranging from NLGI 3 to 0 grades in the research report (see Section 11 ). 1.2 This test method may not be suitable for some greases containing highly volatile components. This test method does not attempt to account for sample evaporation. It is the user's responsibility to determine if evaporation of the sample is a significant contributor to mass loss at the required drying temperature. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 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. For specific warning statements, see 7.3 . 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 This test method estimates the resistance of greases to water washout from ball bearings under conditions of the test. No correlation with field service has been established.
