21、 ISO 4802 is largely based on a method of test approved by the International Commission on Glass (ICG), Technical Committee 2, Chemical Durability and Analysis, for measuring the hydrolytic resistance of the interior surfaces of glass containers.This part of ISO 4802 contains a classification which

22、is related to but not equivalent to the classification set up in ISO 4802-1 for the titration method.5DIN ISO 4802-2:2017-02 Glassware Hydrolytic resistance of the interior surfaces of glass containers Part 2: Determination by flame spectrometry and classification1 ScopeThis part of ISO 4802 specifi

23、es: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 solutio
