ASTM D3336-05(2015)
(Test Method)Standard Test Method for Life of Lubricating Greases in Ball Bearings at Elevated Temperatures
Standard Test Method for Life of Lubricating Greases in Ball Bearings at Elevated Temperatures
SIGNIFICANCE AND USE
4.1 This test method can be used to evaluate the ability of grease to provide adequate lubrication for extended periods of ball bearings operating under light loads at high speeds and elevated temperatures.
SCOPE
1.1 This test method covers the evaluation of the performance of lubricating greases in ball bearings operating under light loads at high speeds and elevated temperatures.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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. For specific warning statements, see 8.1.
