1、Designation: D 1264 03 (Reapproved 2008)An American National StandardStandard Test Method forDetermining the Water Washout Characteristics ofLubricating Greases1This standard is issued under the fixed designation D 1264; the number immediately following the designation indicates the year oforiginal
2、adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript 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
3、.1. Scope1.1 This test method covers the evaluation of the resistanceof a lubricating grease to washout by water from a bearing,when tested at 38 and 79C (100 and 175F) under theprescribed laboratory conditions. It is not to be considered theequivalent of service evaluation tests. This test method m

The values given in parentheses are for informationonly.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its u
5、se. It is theresponsibility of the user this standard to establish appropriatesafety and health practices and determine the applicability ofregulatory limitations prior to use.

6、Determination of Precision and BiasData for Use in Test Methods for Petroleum Products33. Summary of Test Method3.1 The grease is packed into a ball bearing, the bearing isthen inserted in a housing with specified clearances, androtated at 600 6 30 rpm. Water, controlled at the specified testtempera
7、ture, impinges on the bearing housing at a rate of 5 60.5 mL/s. The amount of grease washed out in 60 6 1 min isa measure of the resistance of the grease to water washout.4. Significance and Use4.1 This test method estimates the resistance of greases towater washout from ball bearings under conditio
