Liquid halogenated hydrocarbons for industrial use — Determination of acidity — Titrimetric method

The method does not apply when the halogenated materials hydrolyse at ambient temperature. The principle is based on the titration of the acidity of the aqueous extract from a test portion with a standard volumetric sodium hydroxide solution in the presence of bromocresol green as indicator. - Replaces ISO Recommendation R 1393-1970.
