Formerly under the jurisdiction of Committee D12 on Soaps and Other Detergents, this practice was withdrawn in January 2023 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

These test methods cover the sampling and chemical analysis of paste, powder, or liquid detergent alkylbenzene sulfonates. Reagent grade chemicals shall be used in all tests. The distillation method shall be preferred for moisture testing. Water by the Karl Fischer titration method shall be used when the amount of moisture is low. Total matter insoluble in alcohol, neutral oil content, chlorides calculated as sodium chloride, and pH shall also be tested.

1.1 These test methods cover the sampling and chemical analysis of paste, powder, or liquid detergent alkylbenzene sulfonates.
