Annex Recommended method for the de-activation of glassware

Defines a method for determining the pH of aqueous extract from homopolymer and copolymer resins of vinyl chloride using a pH meter provided with a glass electrode. Not intended for estimation of the electrical qualities of the resin, but may be of interest in the selection of additives, particularly stabilizers, for use in preparing compounds.
