Gas cylinders - Compatibility of cylinder and valve materials with gas contents - Part 2: Non-metallic materials (ISO 11114-2:2013)

ISO 11114-2:2013 gives guidance in the selection and evaluation of compatibility between non-metallic materials for gas cylinders and valves and the gas contents. It also covers bundles, tubes and pressure drums.
ISO 11114-2:2013 can be helpful for composite and laminated materials used for gas cylinders.
It does not cover the subject completely and is intended to give guidance only in evaluating the compatibility of gas/material combinations.
Only the influence of the gas in changing the material and mechanical properties is considered (for example chemical reaction or change in physical state). The basic properties of the materials, such as mechanical properties, required for design purposes are normally available from the materials' supplier and are not considered.
The compatibility data given are related to single component gases but can be used to some extent for gas mixtures. Ceramics, glasses, and adhesives are not covered.
Other aspects such as quality of delivered gas are not considered.
ISO 11114-2:2013 is not intended to be used for cryogenic fluids (see ISO 21010).

Gasflaschen - Verträglichkeit von Flaschen- und Ventilwerkstoffen mit den in Berührung kommenden Gasen - Teil 2: Nichtmetallische Werkstoffe (ISO 11114-2:2013)

Dieser Teil von ISO 11114 liefert eine Anleitung für die Auswahl und Bewertung der Verträglichkeit von nichtmetallischen Werkstoffen für Gasflaschen und Ventile mit den in Berührung kommenden Gasen. Er gilt auch für Bündel, Großflaschen und Druckfässer.
Dieser Teil von ISO 11114 kann für Gasflaschen verwendete Verbund- und Schichtwerkstoffe von Nutzen sein.
Er behandelt das Thema nicht vollständig und ist nur als Hilfestellung zur Bewertung der Verträglichkeit von Gas/Werkstoffkombinationen vorgesehen.
Es wird ausschließlich die Auswirkung des Gases auf Änderungen der Werkstoff- und mechanischen Eigenschaften (z. B. chemische Reaktion oder Änderungen des physikalischen Zustandes) berücksichtigt. Die für Auslegungszwecke notwendigen grundsätzlichen Werkstoffeigenschaften, wie z. B. mechanische Eigenschaften, werden üblicherweise vom Werkstofflieferanten bereitgestellt und in diesem Teil von ISO 11114 nicht berücksichtigt.
Die enthaltenen Verträglichkeitsdaten beziehen sich auf Einzelgase, können jedoch in gewissem Umfang auch für Gasgemische verwendet werden. Dieser Teil von ISO 11114 gilt nicht für Keramiken, Gläser und Klebstoffe.
Andere Gesichtspunkte, wie z. B. die Qualität des gelieferten Gases, werden nicht berücksichtigt.
Dieser Teil von ISO 11114 ist nicht zur Verwendung für tiefkalte Fluide (siehe ISO 21010) bestimmt.

Bouteilles à gaz - Compatibilité des matériaux des bouteilles et des robinets avec les contenus gazeux - Partie 2: Matériaux non métalliques (ISO 11114-2:2013)

L'ISO 11114-2:2013 donne des lignes directrices pour la sélection et l'évaluation de la compatibilité entre les matériaux non métalliques des bouteilles à gaz/robinets avec le gaz. Elle couvre également les cadres, tubes et fûts sous pression.
L'ISO 11114-2:2013 peut se révéler utile pour les matériaux composites et les matériaux stratifiés utilisés pour les bouteilles à gaz.
Elle ne couvre pas la totalité du sujet et n'a pour but que de donner une orientation pour l'évaluation de la compatibilité des combinaisons gaz/matériau.
Seule l'influence du gaz sur la transformation du matériau ou sur la modification de ses propriétés mécaniques est considérée (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 sont en général fournies par le fabricant du matériau et ne sont donc pas abordées dans l'ISO 11114-2:2013.
Les données de compatibilité indiquées se rapportent à des gaz à un composant unique, mais elles peuvent être utilisées dans une certaine mesure pour des mélanges gazeux. Les céramiques, les verres et les adhésifs ne sont pas traités dans l'ISO 11114-2:2013.
D'autres aspects, tels que la qualité du gaz fourni, ne sont pas pris en compte.
L'ISO 11114-2:2013. n'est pas destinée à être utilisée pour les fluides cryogéniques (voir l'ISO 21010).

Plinske jeklenke - Združljivost materialov za ventil in jeklenko s plinom - 2. del: Nekovinski materiali (ISO 11114-2:2013)

Ta del standarda ISO 11114 podaja smernice za izbiro in oceno združljivosti nekovinskih materialov za plinske jeklenke in ventile ter vsebnost plina. Zajema tudi snope, cevi in sode pod tlakom. Ta del standarda ISO 11114 je lahko v pomoč pri sestavljenih in laminiranih materialih, ki se uporabljajo za plinske jeklenke. Tematike ne obravnava v celoti in je namenjen samo svetovanju pri oceni združljivosti kombinacij plina/materiala. Obravnava se samo vpliv plina na spreminjanje materialnih in mehanskih lastnosti (na primer kemijska reakcija ali sprememba fizikalnega stanja). Osnovne lastnosti materialov, kot so mehanske lastnosti, zahtevane za potrebe projektiranja, običajno predloži dobavitelj materialov in niso obravnavane v tem delu standarda ISO 11114. Navedeni podatki o združljivosti se nanašajo na enokomponentne pline, vendar jih je mogoče do določene mere uporabiti za mešanice plinov. Keramika, stekla in lepila niso vključeni v ta del standarda ISO 11114. Drugi vidiki, kot so kakovost dobavljenega plina, niso obravnavani. Ta del standarda ISO 11114 ni namenjen za uporabo za kriogene tekočine (glej standard ISO 21010).

ISO 11114-2:2013(E)
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 11114-2 was prepared by Technical Committee ISO/TC 58, Gas cylinders, in collaboration with
Technical Committee CEN/TC 23, Transportable Gas cylinders in accordance with the Agreement on
technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition, Clauses 4 and 6, and Table 1 of which have been
technically revised. Annex A has been deleted.
ISO 11114 consists of the following parts, under the general title Gas cylinders — Compatibility of cylinder and
valve materials with gas contents:
— Part 1: Metallic materials;
— Part 2: Non-metallic materials;
— Part 3: Autogenous ignition test for non-metallic materials in oxygen atmosphere;

ISO 11114-2:2013(E)
Introduction
This part of ISO 11114 deals with the compatibility of non-metallic materials used for gas cylinders and gas
cylinder valves with the gas contents of the cylinder. Compatibility of metallic materials is treated in
ISO 11114-1.
Non-metallic materials are very often used for the construction of gas cylinder valves as seals, e.g. o-ring,
gland packing, seats, or as lubrication products to avoid friction. They are also commonly used to ensure
sealing of the valve/cylinder connection. For gas cylinders, they are sometimes used as an internal coating or
as a liner for composite materials.
Non-metallic materials not in contact with the gas are not covered by this part of ISO 11114.
This part of ISO 11114 is based on current international experience and knowledge. Some data are derived
from experience involving a mixture of the gas concerned with a dilutant, where no data for single component
gases were available.
This part of ISO 11114 has been written to be in conformity with the UN Recommendations on the Transport
of Dangerous Goods: Model Regulations. When published it will be submitted to the UN Sub Committee of
Experts on the Transport of Dangerous Goods with a request that it be included in the Model Regulations.
Where there is any conflict between this part of ISO 11114 and any applicable regulation, the regulation
always takes precedence.
