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.

Characterizes the product and gives the main impurities. Specifies methods for the determination of the crystallizing point and density and the procedure of the gas chromatographic analysis. Details the principle of determination of the product and its impurities, especially benzal chloride, benzaldehyde, toluene, chlorotoluene, etc., by the gaschromatography (relates to ISO 2818).

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.
