GSO ISO 4802-2:2013 Scope
This part of ISO 4802 specifies:
a) methods 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 determining
the amount of sodium and other alkali metal or alkaline earth oxides in the extraction solution using flame
atomic emission or absorption spectrometry (flame spectrometry);
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.
The test method specified in this part of ISO 4802 might not be applicable to containers whose surfaces have
been treated with silicon (e.g. containers that are ready for direct filling).
