ASTM D6/D6M-95(2011)e1
(Test Method)Standard Test Method for Loss on Heating of Oil and Asphaltic Compounds
Standard Test Method for Loss on Heating of Oil and Asphaltic Compounds
SIGNIFICANCE AND USE
This test method is useful in characterizing certain petroleum products by the determination of their loss of mass upon heating under standardized conditions.
SCOPE
1.1 This test method covers the determination of the loss in mass (exclusive of water) of oil and asphaltic compounds when heated as hereinafter prescribed.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 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 and regulatory limitations prior to use.
