ASTM D1264-18e1

Standard Test Method for Determining the Water Washout Characteristics of Lubricating Greases

SIGNIFICANCE AND USE
4.1 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.
SCOPE
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 10).  
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 6.3.  
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.
