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

SIGNIFICANCE AND USE
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 and 79°C (100 and 175°F) under the prescribed laboratory conditions. It is not to be considered the equivalent of service evaluation tests. This test method may not be suitable for some greases containing highly volatile components.
1.2 The values state in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 6.3.
