ISO 4802-1:1988
ISO 4802‑1:2010 specifies 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. ISO 4802‑1:2010 also specifies 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.
