Abstract

This document specifies: a)       a method for determining the hydrolytic resistance of the interior surfaces of glass containers when subjected to attack by water at (121 ± 1) °C for (60 ± 1) min. The resistance is measured by titration of a known aliquot portion of the extraction solution produced with hydrochloric acid solution, in which case the resistance is inversely proportional to the volume of acid required; b)       a classification of glass containers according to the hydrolytic resistance of the interior surfaces determined by the methods specified in this document.
