Significance and Use | ||||||||
5.1?The loss of volatile materials from greases and oils can adversely affect the original performance characteristics of a lubricant and, therefore, could be a significant factor in evaluating a lubricant for a specific use. Such volatiles can also be considered contaminants in the environment in which the lubricant is to be used. Correlation between results from this test method and service performance has not been established. 5.2?The test method can be used at any specified temperature between 93 ?C and 316 ?C (200 ?F and 600 ?F) that may be agreed upon by the user of the method. (WarningThis test method should not be used at temperatures which exceed the flash point of the base oil of the grease.) Note 1:?The specified flow of air, 2.58 g/min ? 0.02 g/min, (2
L/min at standard temperature and pressure), assumes dry air. It is
not known that the original work involved dry air but it has since
been shown that this can be a factor in reproducibility and should
be addressed. Air with a dew point of less than 10 ?C at standard
temperature and pressure will be satisfactory.

1. Scope | ||||||||
1.1?This test method covers the determination of evaporation loss of lubricating greases at temperatures between 93 ?C and 316 ?C (200 ?F and 600 ?F). This test method is intended to augment Test Method D972, which is limited to 149 ?C (300 ?F). 1.2?The values stated in SI units are to be regarded as the standard. The values 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
