This test method is intended for the determination of the total desulfated matter contained in sulfated oils following their total decomposition with dilute mineral acid.

1. Scope

1.1 This test method covers the determination of the total desulfated fatty matter in a sample of sulfated oils by decomposition with diluted mineral acids and extraction of the decomposed fat. This test method is not applicable to samples that are not completely decomposed upon boiling with mineral acids. This test method was derived from Test Methods D500, Sections 29 through 32.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 of regulatory limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
