【国外标准】 Standard Test Methods for Sampling and Chemical Analysis of Alkylbenzene Sulfonates (Withdrawn 2023)

AbstractThese 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.1.2 The procedures for sampling and analysis appear in the following order:  Sections   Sampling:   Powders and Flakes Packed in Cans or Cartons 3 Powders and Flakes in Bulk 4 Liquids 6 Pastes 7Hazards 8Preparation of Sample 9Moisture:   Distillation Method 11 – 14 Karl Fischer Method 15 – 20Total Matter Insoluble in Alcohol 21 – 23Neutral Oil 24 – 27Chlorides Calculated as Sodium Chloride (NaCl) 28 – 31pH 321.3 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.
