20、 DIN ISO 4802-1:2017-02 5 IntroductionThis part of 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.The

21、European Pharmacopoeia Commission has adopted the principle of the determination by titration and has set up a classification for glass containers for injectable preparations which is now included in this part of ISO 4802. In addition, this part of ISO 4802 contains a classification of containers ot

22、her than for injectable preparations.According to many results of international interlaboratory tests, this part of ISO 4802 specifies the test conditions in more detail than the European Pharmacopoeia in order to increase the reproducibility of the test results. In particular, the autoclaving cycle

23、 is described in detail.DIN ISO 4802-1:2017-02 6Glassware Hydrolytic resistance of the interior surfaces of glass containers Part 1: Determination by titration method and classification1 ScopeThis part of ISO 4802 specifies:a) a method for determining the hydrolytic resistance of the interior surfac

24、es 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

25、 required;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 4802.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indis
