Summary
This document specifies: a) a method for determining the hydrolytic resistance of the internal surfaces of glass containers when subjected to attack by water at (121 ± 1) °C for (60 ± 1) min . Hydrolytic resistance is measured by determining the amount of sodium oxide and other alkali or alkaline earth metal oxides in the extraction solution by flame atomic absorption or emission spectrometry (flame spectrometry ); (b) a classification of glass containers according to the hydrolytic resistance of the internal surfaces determined by the method specified in this document. The test method specified in this document may not be applicable to containers whose surfaces have been treated for functional modifications, such as silicone (e.g. containers ready for direct filling).
