This International Standard specifies methods of analysis of technical sodium alkylarylsulphonates. It covers the following determinations: - Measurement of pH. - Determination of water content - Determination of free alkalinity or free acidity - Determination of matter extractable by light petroleum - Determination of sodium alkylarlsulphonates content - Determination of sodium sulphite content - Determination of sodium sulphate content - Determination of sodium chloride content. It also sets out, in annexes A: a general scheme of analysis; B: a rapid method for the determination of sodium alkylarylsulphonates. This International Standard is applicable to technical sodium alkylarylsulphonates, in paste or powder form, and free from any products extraneous to their manufacture, excluding sodium alkylbenzenesulphonates. It is not applicable to liquid products as these often contain either solvents or additives or both, which would interfere with the method of analysis specified in this International Standard.
