Glassware — Hydrolytic resistance of the interior surfaces of glass containers — Part 1: Determination by titration method and classification
Preview
Summary
This part of ISO 4802 specifies:
a) a method for determining the hydrolytic resistance of the interior surfaces of glass containers
when subjected to attack by water at 121 °C ± 1 °C for 60 min ± 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 part of ISO 4802.
