Significance and Use | ||||||
5.1 Pentane insolubles can include oil-insoluble materials and some oil-insoluble resinous matter originating from oil or additive degradation, or both. 5.2 Toluene insoluble materials can come from (1) external contamination, (2 ) fuel carbon and highly carbonized materials from degradation of fuel, oil, and additives, or (3) engine wear and corrosion materials. 5.3 A significant change in pentane insolubles, toluene insolubles (with or without coagulant), and insoluble resins indicates a change in oil which could lead to lubrication system problems. 5.4 Insolubles measured can also assist in evaluating the performance characteristics of a used oil or in determining the cause of equipment failure. |

1. Scope | ||||||
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. 1.4 The values stated in SI units
are to be regarded as standard. No other units of measurement are
included in this standard.
1.5 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.
