Scope

This International Standard specifies a method for the deter-mination of the pH of the aqueous extract from homopolymer and copolymer resins of vinyl chloride, by means of a pH meter equipped with a glass electrode. This determination is not suitable for estimating the electrical qualities of the resin, but may be of interest in selecting additives and, especially, stabilizers which are to be used for the preparation of compounds.
