【国外标准】 Standard Test Methods for Sampling and Chemical Analysis of Fatty Alkyl Sulfates

AbstractThese test methods cover the sampling and chemical analysis of paste, powder, or liquid detergent fatty alkyl sulfates. The different procedure for sampling and chemical analysis of past, powder, or liquid detergent are presented and discussed in details. Distillation test, titration test, and gravimetric test shall be performed to meet the requirements prescribed. The calculations methods for chlorides as sodium chloride are presented in details.1.1 These test methods cover the sampling and chemical analysis of paste, powder, or liquid detergent fatty alkyl sulfates.1.2 The procedures for sampling and analysis appear in the following order:  SectionsSampling:   Powders and Flakes Packed in Cans or Cartons  4 Powders and Flakes in Bulk  5 Liquids  6 Pastes  7 Preparation of Sample  8 Moisture by the Distillation Test Method 11 – 14 pH 15 Alkalinity 16 – 19 Alcohol-Soluble Matter 20 – 22 Alcohol-Insoluble Matter 23 and 24 Unsulfated Material 25 – 28 Combined Alcohols 29 – 32Ester SO3:   Method A. Titration Test Method 36 and 37  SectionsEster SO3:   Method B. Gravimetric Test Method 38 and 39 Sodium Sulfate 40 – 43 Chlorides Calculated as Sodium Chloride (NaCl) 44 – 471.3 The values stated in either inch-pound or SI units are to be regarded separately as the standard. The values given in parentheses are for information only.1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Material Safety Data Sheets are available for reagents and materials. Review them for hazards prior to usage.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
