Entrainment method using azeotropic distillation with xylene, oven drying method (loss in mass on heating at 150°C) and Karl Fischer method.

This Section of BS 3762 describes methods for determining the content of water or volatile matter in formulated detergents.

NOTE 1 The water determined may include water of crystallization.

Method 1 is for determination of water in samples that do not contain volatile compounds that are miscible with water, for example, low molecular mass alcohols. Method 2 is for determination of the loss in mass on heating at 150 °C, which indicates the volatile matter content; the result will be the water content if water is the only volatile compound in the sample. Method 3 is for determination of water in liquids and in pastes and solids that release all their water during the titration of a solution or a dispersion in methanol; it is not applicable to samples that contain noticeable amounts of oxidizing agents, ketones, strong acids or strong bases.

NOTE 2 The titles of the publications referred to in this Section are listed on the inside back cover.
