D6560-00(2005) Standard Test Method for Determination of Asphaltenes (Heptane Insolubles) in Crude Petroleum and Petroleum Products
Developed by Subcommittee: D02.14
Book of Standards Volume: 05.04
1. Scope
1.1 This test method covers a procedure for the determination of the heptane insoluble asphaltene content of gas oil, diesel fuel, residual fuel oils, lubricating oil, bitumen, and crude petroleum that has been topped to an oil temperature of 260?C (see ).
1.2 The precision is applicable to values between 0.50 and 30.0 % m/m. Values outside this range may still be valid but may not give the same precision values.
1.3 Oils containing additives may give erroneous results.
1.4 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.

1.5 This annex covers a procedure for the preparation of a crude petroleum residue (topped to an oil temperature of 260C) suitable for the determination of asphaltene content (see ).
