Gas cylinders - Valve protection caps, guards and shrouds - Design, construction and tests (ISO 11117:2019)

This Standard specifies the requirements for valve protection caps and valve guards used on cylinders for liquefied, dissolved or compressed gases. Valve protection caps and valve guards are some of the options available to protect cylinder valves, including valves with integral pressure regulators (VIPRs) during transport. This document is applicable to valve protection caps and valve guards which inherently provide the primary protection of a cylinder valve. It can also be used to test other equipment (e.g., handling devices) attached to cylinder packages, even in cases where the cylinder valve is inherently able to withstand damage without release of the content. This document excludes protection devices for cylinders with a water capacity of 5 l or less and cylinders whereby the protection device is fixed by means of lugs welded or brazed to the cylinder, or is welded or brazed directly to the cylinder. This document does not cover valve protection for breathing apparatus cylinders. This document does not specify requirements that could be necessary to enable the valve protection device to be used for lifting the cylinder.

Gasflaschen - Ventilschutzkappen, Schutzkörbe und Schutzkragen - Auslegung, Bau und Prüfungen (ISO 11117:2019)

Dieses Dokument legt die Anforderungen an Ventilschutzkappen und Ventilschutzkörbe fest, die für Flaschen für verflüssigte, gelöste oder verdichtete Gase verwendet werden.
Ventilschutzkappen und Ventilschutzkörbe sind einige der für den Schutz von Flaschenventilen, einschließlich Ventile mit integriertem Druckregler [en: Valves with Integrated Pressure Regulator] (VIPR), bei der Beförderung verfügbaren Möglichkeiten.
Dieses Dokument ist auf Ventilschutzkappen und Ventilschutzkörbe anwendbar, die auslegungsgemäß für den primären Schutz eines Flaschenventils sorgen. Es kann auch für die Prüfung anderer an die betreffenden Flascheneinheiten angebrachten Ausrüstungsteile (z. B. Einrichtungen zur Handhabung) angewendet werden, und zwar selbst dann, wenn das Flaschenventil auslegungsgemäß in der Lage ist, einer Beschädigung ohne Freisetzung des Inhalts standzuhalten.
Dieses Dokument schließt Schutzeinrichtungen für Flaschen mit einem Fassungsraum bis einschließlich 5 l sowie Flaschen aus, bei denen die Schutzeinrichtung mit Hilfe von an der Flasche angeschweißten oder gelöteten Ösen befestigt wird oder direkt an die Flasche angeschweißt oder gelötet wird. Dieses Dokument deckt nicht den Ventilschutz für Flaschen von Atemgeräten ab.
ANMERKUNG Kleine Flaschen (z. B. medizinische Flaschen) werden üblicherweise in einer Umverpackung (z. B. auf einer Palette) befördert, um Beförderungsvorschriften einzuhalten.
Dieses Dokument legt keine Anforderungen fest, die erforderlich sein könnten, um die Ventilschutzvorrichtung auch zum Anheben der Flasche verwenden zu können

Bouteilles à gaz - Chapeaux fermés, chapeaux ouverts et cols de protection des robinets - Conception, construction et essais (ISO 11117:2019)

Le présent document spécifie les exigences relatives aux chapeaux fermés et aux chapeaux ouverts de protection des robinets, utilisés sur des bouteilles à gaz pour gaz liquéfiés, dissous ou comprimés.
Les chapeaux fermés et les chapeaux ouverts de protection des robinets font partie des options disponibles pour protéger les robinets de bouteilles, y compris les robinets avec régulateurs de pression intégrés (VIPR) pendant le transport.
Ce document s'applique aux chapeaux fermés et aux chapeaux ouverts de protection des robinets qui assurent de manière inhérente la principale protection d'un robinet de bouteille. Il peut également être utilisé pour soumettre à essai d'autres équipements (par exemple des dispositifs de manutention) fixés aux emballages, même dans les cas où le robinet de bouteille peut intrinsèquement résister aux dommages sans libérer son contenu.
Le présent document exclut les dispositifs de protection des robinets équipant les bouteilles à gaz ayant une contenance en eau de 5 l ou moins et les bouteilles sur lesquelles le dispositif de protection est fixé au moyen d'attaches soudées ou brasées sur la bouteille, ou est soudé ou brasé directement sur la bouteille. Ce document ne traite pas des dispositifs de protection des robinets équipant les bouteilles à gaz reliées aux appareils respiratoires.
NOTE       Les petites bouteilles à gaz (par exemple bouteilles à gaz à usage médical) sont généralement transportées dans un suremballage (par exemple sur une palette) pour satisfaire aux réglementations en matière de transport.
Le présent document ne spécifie pas les exigences qui pourraient être demandées au dispositif de protection du robinet pour qu'il puisse servir à soulever la bouteille.

Plinske jeklenke - Zaščitne kape in varovala ventilov plinskih jeklenk - Konstruiranje, izdelava in preskusi (ISO 11117:2019)

Ta standard določa zahteve za zaščitne kape in varovala ventilov, ki se uporabljajo na jeklenkah za utekočinjene, raztopljene ali stisnjene pline. Zaščitne kape in varovala ventilov so ena od razpoložljivih možnosti za zaščito ventilov za jeklenke, vključno z ventili z vgrajenimi tlačnimi regulatorji (VIPR), med prevozom. Ta dokument se uporablja za zaščitne kape in varovala ventilov, ki zagotavljajo primarno zaščito ventilov za jeklenke. Uporablja se lahko tudi za preskušanje druge opreme (npr. naprav za upravljanje), ki je pritrjena na embalažo jeklenk, celo v primerih, ko lahko ventil za jeklenke vzdrži poškodbe brez izpusta vsebine. Ta dokument ne zajema zaščitnih naprav za jeklenke z vodno kapaciteto 5 l ali manj in za jeklenke, pri katerih je zaščitna naprava pritrjena na jeklenko z zvarjenimi ali spajkanimi ročaji oziroma je zavarjena ali spajkana neposredno na jeklenko. Ta dokument ne zajema zaščite ventilov za jeklenke dihalnih aparatov. Ta dokument ne določa zahtev, ki so morda potrebne za omogočanje uporabe zaščitne naprave ventilov za dvigovanje jeklenk.

Gas cylinders — Valve protection caps and guards —
Design, construction and tests
1 Scope
This document specifies the requirements for valve protection caps and valve guards used on cylinders
for liquefied, dissolved or compressed gases.
Valve protection caps and valve guards are some of the options available to protect cylinder valves,
including valves with integral pressure regulators (VIPRs) during transport.
This document is applicable to valve protection caps and valve guards which inherently provide the
primary protection of a cylinder valve. It can also be used to test other equipment (e.g., handling
devices) attached to cylinder packages, even in cases where the cylinder valve is inherently able to
withstand damage without release of the content.
This document excludes protection devices for cylinders with a water capacity of 5 l or less and
cylinders whereby the protection device is fixed by means of lugs welded or brazed to the cylinder, or is
welded or brazed directly to the cylinder. This document does not cover valve protection for breathing
apparatus cylinders.
NOTE Small cylinders (e.g., medical cylinders) are commonly transported in an outer-packaging (e.g., pallet)
to meet transport regulations.
This document does not specify requirements that could be necessary to enable the valve protection
device to be used for lifting the cylinder.

Note 2 to entry: The total package mass is expressed in kg.
4 General requirements for valve protection cap and valve guard
4.1 Valve protection cap
A valve protection cap shall be of adequate strength to protect the valve.
It shall be capable of being securely fixed to the cylinder, either by screwed thread or other suitable means.
Figure 1 gives examples of valve protection caps.
The dimensions given in Figure 1 are only mandatory in the special case that valve protection caps are
designed to protect valves that have dimensions in accordance with Figure 2, and that the value c for
the height to the reference plane "top of the cylinder" (Key 1) in Figure 3 is as given there (i.e., ≤25 mm).
Such valve protection caps will be eligible for a specific marking (see Clause 8).
Provision should be made to assist fitting or removal of the valve protection cap, for example, by
inclusion of a hexagonal boss enabling use of a wrench.
NOTE Some valve protection caps not containing an inherent removal provision can be removed using a
special tool.
The valve protection cap shall be provided with sufficient venting capacity equating to a cross-sectional
2
area of at least 157 mm for a typical conventional cylinder valve.
Possible examples are:
— using two or more vent holes of at least 10 mm diameter (see Figure 1) situated symmetrically so
that any thrust caused by venting gas is balanced,
— using other means of venting, e.g., lifting under pressure (see Figure 6 a).
Quick-release cylinder valves as designed according to ISO 17871 can have a larger discharge capacity
than typical conventional cylinder valves. In such a case, the venting capacity of the valve protection
cap shall be assessed.
Water drainage shall be considered for all types of valve protection caps.
If a threaded fixing connection is used, it is recommended to conform to the dimensions given in
Figure 4 or Figure 5. The valve protection cap shall be of such dimensions as not to contact any part of
the valve.

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).

Introduction
This document covers devices intended for the protection of cylinder valves, where such protection is
fitted to allow safe transport, handling and storage.
This document specifies the principal dimensions, requirements for fitment and drop test procedure, to
confirm the provision of adequate valve protection, in the event of the occurrence of a cylinder toppling
from its base.
This standard has been written so that it is suitable to be referenced in the UN Model Regulations.

Gas cylinders — Valve protection caps, guards and shrouds
— Design, construction and tests
1 Scope
This document specifies the requirements for valve protection caps, valve guards and shrouds used on
cylinders for liquefied, dissolved or compressed gases.
Valve protection caps, valve guards or shrouds are some of the options available to protect cylinder
valves (including Valves with Integral Pressure Regulators, abbreviated VIPRs) during transport.
While this document is applicable to valve protection caps, valve guards and shrouds which inherently
provide the primary protection of a cylinder valve, it might also be beneficially used to test other
equipment attached to cylinder packages, even in cases where the cylinder valve is inherently able to
withstand damage without release of the content.
NOTE Small cylinders (e.g. medical) are commonly transported in an outer-packaging (e.g. pallet) to meet
transport regulations.
This document does not specify requirements that might be necessary to enable the valve protection
device to be used for lifting the cylinder.

shroud
integral and permanent part of a cylinder or pressure drum for valve protection during transport,
handling and storage
[SOURCE: ISO 10286:2015, 362, "valve shroud", modified – "and permanent" was added, and "welded"
was removed in front of "cylinder"]
3.4
test valve
valve used for the drop test to qualify the valve protection device
3.5
permitted mass
maximum mass of the cylinder package, including its permanent attachments and its maximum
contents, to which the protection device is intended to be fixed
4 General requirements
4.1 Valve protection cap and guard
4.1.1 Valve protection cap
A valve protection cap shall be of adequate strength to protect the valve.
It shall be capable of being securely fixed to the cylinder, either by screwed thread or other suitable means.
Provision should be made to assist fitting or removal of the valve protection cap, for example, by
inclusion of a hexagonal boss enabling use of a wrench.
NOTE 1 Some valve protection caps not containing an inherent removal provision can be removed using a
special tool.
The valve protection cap shall be provided with sufficient venting capacity equating to a cross sectional
2
area of at least 157 mm for a typical conventional cylinder valve.
NOTE 2 For caps designed to be used for very large discharge valves, e.g. quick-release cylinder valves for fire
suppression systems, the venting capacity needs to match the potential discharge rate of the valve.
Possible examples are:
— using two or more vent holes of at least 10 mm diameter (see Figure 1) situated symmetrically so
that any thrust caused by venting gas is balanced,
— using other means of venting, e.g. lifting under pressure (see Figure 6, ).
Valve protection caps designed to protect valves that have dimensions in accordance with Figure 2,
as applicable, shall conform to dimensions given in Figure 1 and preferably Figure 5 where a threaded
fixing connection is used. Valve protection caps designed for use with valves with larger dimensions
shall be tested with the intended largest valve. The valve protection cap shall be of such dimensions as
not to contact any part of the valve.
For thread dimensions, see Table 1 and Table 2.

The outlines and dimensions given are typical for ISO valve protection caps in common use. Any other shape,
dimensions and/or connection thread may be used (e.g. Ø 3" 1/8 × 11 UN), provided they give appropriate clearance
around the valve.
The 80 mm fixing connection is shown. Alternative sizes, e.g. 78 mm, may be used. Valve protection caps for such
cylinders should have the appropriate dimensions.
Water drainage should be considered for all types of valve protection cap.
Figure 1 — Basic dimensions of valve protection caps for valves according to Figure 2
Key
r ≤ 32,5 mm h ≤ 90 mm
R ≤ 38 mm L ≤ 125 mm
R shall be measured to the part of the valve furthest from the valve stem axis and includes any valve outlet plugs or
caps if fitted
NOTE 1 h represents the length of the lower part of the valve when R is greater than r.
NOTE 2 L is the overall length of the valve along the axis of the valve inlet connection in the closed position
when not fitted to a cylinder.
NOTE 3 r relates to the axis of the valve inlet connection and not to the centreline of the valve operating device.
NOTE 4 This Figure is identical with ISO 10297:2014, Figure 9.

It shall be fixed so as to prevent inadvertent removal by the end user or dismantling under normal
service conditions.
Consideration shall be given to the design of valve guards fixed only to the valve to ensure the valve
guard does not initiate unscrewing of the valve from the cylinder.
The design of valve guards and their mounting on the cylinder package shall permit ease of access for
valve operation and assembly of operational equipment. Rotational valve guards shall be capable of
easy manual orientation to allow alignment of openings with the valve connections.
If the valve guard is fixed only to the valve and not fixed to the cylinder then in addition to the
requirements for valve guards included in this document, the valve type, in an unguarded state, shall
pass the valve impact test according to ISO 10297:2014, Annex A.
NOTE In this situation the valve to cylinder connection has to withstand impact load. Its capability to
withstand these loads has to be verified.
Figure 3 gives recommended clearance dimensions of the valve guard in relation to a typical cylinder
valve to allow access to the handwheel and to the outlet connection.
Any openings in the side of the valve guard shall not extend below the reference plane.
Provisions for water drainage shall be considered.
