These 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.
