Note: In the event of conflict between the Korean and English language, the Kor
3、ean language shall take precedence. 1.1 Purpose. This standard specifies the test method of determination of pentane and toluene insoluble in used lubricating oils. 1.2 Applicability. 1.2.1 Method A. Applies to the determination of insoluble without the use of coagulant in the pentane and toluene. 1
4、.2.2 Method B. Applies to the determination of insoluble in oils containing detergents by employing a coagulant for both pentane and toluene insoluble. 2 References Note: Only the latest approved standards are applicable unless otherwise specified. 2.1 External Standards/Specifications.

GM KOREA ENGINEERING STANDARDS EDS-T-7710 Copyright 2011 General Motors Company All Rights Reserved November 2011 Page 6 of 6 Version : 4 Toluene Insoluble: The portion of pentane insoluble not soluble in toluene. These materials can come from external contamination, fuel carbon and highly
9、carbonized materials from degradation of fuel, oil, and additives, or engine wear and corrosion materials. Coagulated Pentane Insolubles: Include the matter dispersed in suspension because of the Pentane Insoluble and the dispersant characteristics of the oil. Coagulated Toluene Insolubles: The port
10、ion of coagulated pentane insolubles not soluble in toluene. These materials include the matter separated by using the coagulant and toluene insolubles. Insolubles Resins: Separated matter soluble in toluene but not pentane. These can be calculated for either method A or B by subtracting the toluene
11、 insolubles from the pentane insolubles. 7.2 Acronyms, Abbreviations, and Symbols.
