This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

Standard Test Method for
Determining the Water Washout Characteristics of
Lubricating Greases
This standard is issued under the fixed designation D 1264; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
´ NOTE—Updated adjunct information and deleted apparatus footnote editorially in November 2003.
1. 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.

3. Summary of Test Method
3.1 The grease is packed into a ball bearing, the bearing is then inserted in a housing with specified clearances, and rotated at
600 6 30 rpm. Water, controlled at the specified test temperature, impinges on the bearing housing at a rate of 5 6 0.5 mL/s. The
amount of grease washed out in 60 6 1 min is a measure of the resistance of the grease to water washout.
4. 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.
5. Apparatus
5.1 Ball Bearing, ASTM test bearing size 6204 (see ADJD3336).

transformers or thermostats.
5.5 Thermometer or Thermocouple , to determine the temperature of the water reservoir.
