Gas cylinders - Compatibility of cylinder and valve materials with gas contents - Part 2: Non-metallic materials (ISO 11114-2:2021)
This document gives guidance on the selection and evaluation of compatibility between non-metallic materials for gas cylinders and valves and the gas contents. It is also applicable to tubes, pressure drums and bundles of cylinders.
This document covers composite and laminated materials used for gas cylinders. It does not include ceramics, glasses and adhesives.
This document considers the influence of the gas in changing the material and mechanical properties (e.g. chemical reaction or change in physical state). The basic properties of the materials, such as mechanical properties required for design purposes (normally available from the materials supplier), are not considered. Other aspects, such as quality of delivered gas, are not considered.
The compatibility data given are related to single component gases but can be applicable to gas mixtures.
This document does not apply to cryogenic fluids (this is covered in ISO 21010).
Gasflaschen - Verträglichkeit von Werkstoffen für Gasflaschen und Ventile mit den in Berührung kommenden Gasen - Teil 2: Nichtmetallische Werkstoffe (ISO 11114-2:2021)
Dieses Dokument enthält eine Anleitung für die Auswahl und Bewertung der Verträglichkeit von nichtmetallischen Werkstoffen für Gasflaschen und Ventile mit den in Berührung kommenden Gasen. Es ist auch für Großflaschen, Druckfässer und Flaschenbündel anwendbar.
Dieses Dokument behandelt Verbund- und Schichtwerkstoffe, die für Gasflaschen verwendet werden. Es umfasst nicht Keramiken, Gläser und Klebstoffe.
Dieses Dokument berücksichtigt die Auswirkung des Gases auf Änderungen der Werkstoff- und mechanischen Eigenschaften (z. B. chemische Reaktion oder Änderungen des physikalischen Zustandes). Die für Auslegungszwecke notwendigen grundsätzlichen Werkstoffeigenschaften, wie z. B. mechanische Eigenschaften, werden nicht berücksichtigt (werden üblicherweise vom Werkstofflieferanten bereitgestellt). Andere Gesichtspunkte, wie z. B. die Qualität des gelieferten Gases, werden nicht berücksichtigt.
Die enthaltenen Verträglichkeitsdaten beziehen sich auf Einzelgase, können jedoch auch für Gasgemische anwendbar sein.
Dieses Dokument ist nicht anzuwenden für tiefkalte Fluide (dies ist von ISO 21010 abgedeckt).
Bouteilles à gaz - Compatibilité des matériaux des bouteilles et des robinets avec les contenus gazeux - Partie 2: Matériaux non métalliques (ISO 11114-2:2021)
Le présent document donne des recommandations pour la sélection et l’évaluation de la compatibilité entre les matériaux non métalliques des bouteilles à gaz/robinets avec le gaz. Il s’applique également aux tubes, aux fûts sous pression et aux cadres de bouteilles.
Le présent document couvre les matériaux composites et les matériaux stratifiés utilisés pour les bouteilles à gaz. Il n’inclut pas les céramiques, les verres ni les adhésifs.
Le présent document traite de l’influence du gaz sur la transformation du matériau ou sur la modification de ses propriétés mécaniques (par exemple une réaction chimique ou une modification de l’état physique). Les propriétés fondamentales des matériaux, telles que les propriétés mécaniques requises pour la conception d’un produit (en général fournies par le fabricant du matériau), ne sont donc pas abordées. D’autres aspects, tels que la qualité du gaz fourni, ne sont pas pris en compte.
Les données de compatibilité indiquées se rapportent à des gaz à un composant unique, mais elles peuvent être applicables aux mélanges gazeux.
Le présent document ne s’applique pas aux fluides cryogéniques (qui font l’objet de la norme ISO 21010).
Plinske jeklenke - Združljivost materialov za ventil in jeklenko s plinom - 2. del: Nekovinski materiali (ISO 11114-2:2021)
Ta dokument podaja smernice za izbiro in oceno združljivosti nekovinskih materialov za plinske jeklenke in ventile ter vsebnost plina. Uporablja se tudi za cevi, tlačne valje in sklope jeklenk.
Ta dokument zajema kompozitne in laminirane materiale, ki se uporabljajo za plinske jeklenke. Ne vključuje keramike, stekla in lepil.
Ta dokument obravnava vpliv plina na spreminjanje lastnosti materialov in mehanskih lastnosti (npr. kemijska reakcija ali sprememba fizikalnega stanja). Osnovne lastnosti materialov, kot so mehanske lastnosti, zahtevane za potrebe projektiranja (običajno jih predloži dobavitelj materialov), niso obravnavane. Drugi vidiki, kot je kakovost dobavljenega plina, niso obravnavani.
Navedeni podatki o združljivosti se navezujejo na enokomponentne pline, vendar jih je mogoče uporabiti za mešanice plinov.
Ta dokument se ne uporablja za kriogene tekočine (to je zajeto v standardu ISO 21010).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

This third edition cancels and replaces the second edition (ISO 11114-2:2013), which has been
technically revised. The main changes compared with the previous edition are as follows:
— new materials were added in Table 1;
— Table 2, dedicated to the compatibility for liners, was added.
