Glassware. Hydrolytic resistance of the interior surfaces of glass containers - Determination by titration method and classification

•

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.

BSI recommends this version of standard for organisations operating in or with the UK. The ISO edition is available here if required.
