Standard Test Method for Determining the Resistance of Lubricating Grease to Water Spray
SIGNIFICANCE AND USE
5.1 This test method is used to evaluate the ability of a grease to adhere to a metal surface when subjected to direct water spray. The results obtained from the use of this test method suggest correlation in operations involving direct water spray impingement such as steel mill roll neck bearing service.4 This test method is used for quality control and purchase specifications.
SCOPE
1.1 This test method2 covers 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 standard.
1.2.1 Exception—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 of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
