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.
