Gas cylinders - Cylinder valves - Manufacturing tests and examinations (ISO 14246:2022)
This document specifies the procedures and acceptance criteria for manufacturing tests and examinations (sometimes called "initial inspection and tests") of valves designed and type tested in accordance with ISO 10297.
This document is applicable to:
a) cylinder valves intended to be fitted to refillable transportable gas cylinders;
b) main valves (excluding ball valves) for cylinder bundles;
c) cylinder valves or main valves with integrated pressure regulator (VIPR);
d) valves for pressure drums and tubes.
NOTE Where there is no risk of ambiguity, cylinder valves, main valves, VIPR and valves for pressure drums and tubes are addressed with the collective term “valves” within this document.
The principles of these manufacturing tests and examinations can be beneficially applied to cylinder valves type tested to national or International Standards other than ISO 10297.
Gasflaschen - Flaschenventile - Herstellungsprüfungen und untersuchungen (ISO 14246:2022)
Dieses Dokument legt die Verfahren und Annahmekriterien für Herstellungsprüfungen und untersuchungen (manchmal als „erstmalige Prüfung“ bezeichnet) für Ventile fest, die nach ISO 10297 ausgelegt und baumustergeprüft wurden.
Dieses Dokument gilt für
a) Flaschenventile für wiederbefüllbare ortsbewegliche Gasflaschen,
b) Hauptabsperrventile (ausgenommen Kugelhähne) für Flaschenbündel,
c) Flaschenventile oder Hauptabsperrventile mit integriertem Druckregler (VIPR, en: valve with integrated pressure regulator), und
d) Ventile für Druckfässer und rohre.
ANMERKUNG Sofern keine Gefahr der Mehrdeutigkeit besteht, werden Flaschenventile, Hauptabsperrventile, VIPR und Ventile für Druckfässer und rohre in diesem Dokument zusammengefasst mit dem Begriff „Ventile“ bezeichnet.
Die Grundsätze dieser Herstellungsprüfungen und untersuchungen können nutzbringend auf Flaschenventile angewendet werden, die nach nationalen oder nach von ISO 10297 abweichenden Internationalen Normen baumustergeprüft wurden.
Bouteilles à gaz - Robinets de bouteilles à gaz - Essais de fabrication et contrôles (ISO 14246:2022)
Le présent document décrit les modes opératoires et les critères d’acceptation applicables aux essais de fabrication et aux contrôles (parfois appelés «inspection initiale et essais») des robinets conçus et soumis à des essais de type conformément à l’ISO 10297.
Le présent document s’applique:
a) aux robinets de bouteilles destinés à être montés sur des bouteilles à gaz transportables et rechargeables;
b) aux vannes principales (à l’exception des robinets à boisseau sphérique) pour cadres de bouteilles;
c) aux robinets de bouteilles ou aux robinets principaux avec détendeur intégré (VIPR);
d) aux robinets de fûts à pression et de tubes.
NOTE Lorsqu’il n’y a pas de risque d’ambiguïté, les robinets de bouteilles, les vannes principales, les VIPR et les robinets de fûts à pression et de tubes sont désignés par le terme générique «robinets» dans le présent document.
Les principes de ces essais de fabrication et de ces contrôles peuvent être appliqués avantageusement à des robinets de bouteilles ayant été soumis à des essais de type conformément à des Normes nationales ou internationales autres que l’ISO 10297.
Plinske jeklenke - Ventili za plinske jeklenke - Preskusi in pregledi med proizvodnjo (ISO 14246:2022)
Ta dokument določa postopke in kriterije sprejemljivosti za preskuse in preglede med proizvodnjo (včasih imenovani »začetni pregledni preskusi«) ventilov, ki so bili načrtovani in tipsko preskušeni v skladu s standardom ISO 10297.
Ta dokument se uporablja za:
a) ventile jeklenk, ki so predvideni za namestitev na ponovno polnljive premične plinske jeklenke;
b) glavne ventile (brez krogelnih ventilov) za sklope jeklenk;
c) ventile za jeklenke ali glavne ventile z vgrajenim regulatorjem tlaka (VIPR);
d) ventile za tlačne valje in cevi.
OPOMBA: Če ne obstaja tveganje dvoumnosti, so ventili za jeklenke, glavni ventili, ventili z vgrajenim regulatorjem tlaka in ventili za tlačne valje in cevi v tem dokumentu imenovani s skupnim izrazom »ventili«.
Načela teh preskusov in pregledov med proizvodnjo je mogoče koristno uporabiti za ventile za jeklenke, ki so bili tipsko preskušeni v skladu z nacionalnim ali mednarodnim standardom, ki ni standard ISO 10297.

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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO’s adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 2,
Cylinder fittings, in collaboration with the European Committee for Standardization (CEN) Technical
Committee CEN/TC 23, Transportable gas cylinders, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 14246:2014), which has been technically
revised. It also incorporates Amendment ISO 14246:2014/Amd 1:2017. The main changes are as follows:
— in Clause 4, a maximum level of hydrocarbon contamination of 220 mg/m and a maximum particle
size of 200 µm has been introduced for valves for oxygen and other oxidizing gases for general
purpose applications, and the mandatory reference to ISO 15001 has been changed to an example
for medical applications;
— in 5.2, indent c), the value of the test pressure for specific acetylene valves has been reduced from
37 bar to 35 bar;
— in 5.4, the requirements concerning the verification of the assembly with regard to the use of correct
components and assembly torques have been clarified.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Introduction
This document covers the function of a valve as a closure (defined by the UN Model Regulations).
Additional features of valves (e.g. pressure regulators, residual pressure-retaining devices, non-return
devices and pressure relief devices) might be covered by other standards and/or regulations.
Valves conforming to this document can be expected to perform satisfactorily under normal service
conditions.
This document pays particular attention to manufacturing tests and examinations of valves designed
and type tested in accordance with ISO 10297.
[1]
This document has been written so that it is suitable to be referenced in the UN Model Regulations .
In this document, the unit bar is used, due to its universal use in the field of technical gases. It should,
however, be noted that bar is not an SI unit, and that the corresponding SI unit for pressure is Pa
5 5 2
(1 bar = 10 Pa = 10 N/m ).
Pressure values given in this document are given as gauge pressure (pressure exceeding atmospheric
pressure) unless noted otherwise.
