scope:

This test method standard is composed of standard test methods for sampling, inspecting, and testing lubricants, liquid fuels, and related products. It is issued pursuant to the Federal Property and Administration Services Act of 1949, as amended, and its application to the purchase of commodities referred to herein is mandatory on all Federal agencies.

The test methods of this standard, when cited in a specification, form an integral part of that specification. Such a citation, although referenced to the basic number of a method, is intended to apply to the latest version of the method as revised (see paragraph 2) and as amended by any subsequent Change Notices to this Standard.

CAUTION

Change Notices are not cumulative. Therefore all notices must be consulted to insure that the latest requirements are observed.

Some methods are identical to those published by the American Society for Testing and Materials (ASTM). These methods are listed in the indexes, together with their corresponding ASTM method numbers, and the details of such test methods are omitted from this standard.

This method describes the test procedure and apparatus for the determination of evaporation loss of lubricating greases and oils for applications where evaporation loss is a factor. Evaporation loss data can be obtained at any temperature in the range 99° C to 538° C (210° F to 1,000° F).
