ASTM D4049-99(2004)

Standard Test Method for Determining the Resistance of Lubricating Grease to Water Spray

SCOPE
1.1 This test method  evaluates the ability of a grease to adhere to a metal surface, when subjected to a water spray under prescribed laboratory conditions.  
1.2 The values stated 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 problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
