Abstract

This document specifies:

a)听听听听听听 a method for determining the hydrolytic resistance of the interior surfaces of glass containers when subjected to attack by water at (121聽卤聽1)聽掳C for (60聽卤聽1)聽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)听听听听听听 a classification of glass containers according to the hydrolytic resistance of the interior surfaces determined by the methods specified in this document.
