适用范围

1.1 This test method covers the determination of pentane and toluene insolubles in used lubricating oils.

1.2 Procedure A covers the determination of insolubles without the use of coagulant in the pentane. It provides an indication of the materials that can readily be separated from the oil-solvent mixtures by centrifuging.

1.3 Procedure B covers the determination of insolubles in oils containing detergents and employs a coagulant for both the pentane and toluene insolubles. In addition to the materials separated by using Procedure A, this coagulation procedure separates some finely divided materials that may be suspended in the oil.

Note 1

Results obtained by Procedures A and B should not be compared since they usually give different values. The same procedure should be employed when comparing values obtained periodically on an oil in use or when comparing results determined by two or more laboratories.

1.4 The values stated in acceptable SI units are to be regarded as the standard.
