Dieser Teil von ISO 11114 legt Prüfverfahren und die Bewertung von Ergebnissen aus diesen Prüfungen fest, um die Eignung von Stählen zur Herstellung von Gasflaschen (mit einem Fassungsraum bis zu 3 000 l) für Wasserstoff und andere versprödenden Gase festzustellen.
Dieser Teil von ISO 11114 gilt nur für nahtlose Gasflaschen aus Stahl.
Die Anforderungen dieses Teils von ISO 11114 sind nicht anwendbar, wenn mindestens eine der folgenden Bedingungen für den vorgesehenen Gasbetrieb erfüllt ist ), wenn:
-   der Arbeitsdruck des zu füllenden versprödenden Gases weniger als 20 % des Prüfdruckes der Flasche beträgt;
der Partialdruck des zu füllenden versprödenden Gases aus einem Gasgemisch im Falle von Wasserstoff und anderen versprödenden Gasen weniger als 5 MPa (50 bar) beträgt, mit Ausnahme von Schwefelwasserstoff und Methylmercaptan, bei denen der Partialdruck 0,25 MPa (2,5bar) nicht überschritten werden darf.

L'ISO 11114-4:2005 spécifie des méthodes d'essai et l'évaluation des résultats de ces essais permettant de retenir les aciers pouvant être utilisés pour fabriquer des bouteilles à gaz (jusqu'à 3 000 l) pour l'hydrogène et d'autres gaz fragilisants.
Elle s'applique uniquement aux bouteilles à gaz en acier sans soudure.
Les exigences de l'ISO 11114-4:2005 ne s'appliquent pas si au moins l'une des conditions suivantes concernant l'utilisation avec le gaz prévu, est remplie:
- la pression d'utilisation du gaz fragilisant dans la bouteille représente moins de 20 % de la pression d'épreuve de la bouteille;
- la pression partielle du gaz fragilisant du mélange gazeux contenu dans la bouteille représente moins de 5 MPa (50 bar) dans le cas de l'hydrogène et d'autres gaz fragilisants, sauf pour le sulfure d'hydrogène et le méthyle de mercaptan pour lesquels la pression partielle ne doit pas dépasser 0,25 MPa (2,5 bar).
