ASTM D1951-86(1995)e1 PDF

1.1 This test method covers the determination of the residue or ash resulting from ignition, under prescribed conditions, of all natural and synthetic drying oils and their fatty acids. This test method is not applicable to boiled oils.

Note 1-Boiled oils do not give reproducible results. Lead driers are partially reduced by the carbon to give metallic lead and oxides of variable composition, and zinc oxide is relatively volatile at the muffle furnace temperature. Ash determinations on boiled oils consequently are empirical and not highly reproducible.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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 whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 4.
