Applicable to products the acidity of which is between 2 mol and 200 mol of univalent acid per kg. Two procedures are given: one is applicable to liquid products (R11, R113, etc.) and the other one to gaseous (R12, R22, etc.). The principle consists in extraction of the acids by water. Titration of the acids in the aqueous phase with standard volumetric sodium hydroxide solution in the presence of bromocresol green as indicator. A figure shows an apparatus for absorption of acids for products which are gaseous at ordinary temperatures.

These methods are applicable to products not contaminated by an axtraneous phase (for example, water). Accidental pollution is also considered. Three cases are considered: small containers, large containers and continuous sampling. The procedure consists in formation of a blended bulk sample, representing the whole of the batch, by mixing several samples. The number and the method of taking of the elementary samples will depend on the number and capacity of containers.

The document specifies the sampling, the measurement of colour in Hazen units, determination of distillation characteristics, determination of density at 20 °C, determination of residue on evaporation, determination of water content, determination of the cloud point and the determination of carbon disulphide content. The principle of the CS2 determination is based on reaction of the carbon disulphide, in the presence of Cu(II) ions and diethylamine, to form copper diethyldithiocarbamate. This compound is soluble in the product which is tested giving a yellow colour the intensity of which is a function of the carbon disulphide content.
