(Main)Small medical gas cylinders - Pin-index yoke-type valve connections (ISO 407:2023)
Small medical gas cylinders - Pin-index yoke-type valve connections (ISO 407:2023)
This document is applicable to pin-index yoke-type valve connections for medical gas cylinders, with a working pressure up to a maximum of 200 bar or test pressure up to a maximum of 300 bar, or both.
NOTE 1 This type of connection is primarily used for small cylinders (5 l or below).
NOTE 2 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 (1 bar = 105 Pa = 105 N/m2).
This document specifies:
— basic dimensions;
— requirements for alternative designs of the yoke-type valve connections;
— dimensions and positions for the holes and pins for the outlet connections.
It also specifies the dimensions and positions for the holes and pins for the outlet connections for gases and gas mixtures.
Kleine Gasflaschen für die medizinische Anwendung - Ventilseitenstutzen mit Anschlussbügel nach dem PIN-Index-System (ISO 407:2023)
Dieses Dokument ist anwendbar für Bügelverschlüsse nach dem Pin-Index-System für Gasflaschen für die medizinische Anwendung mit einem maximalen Prüfdruck bis 200 bar oder einem maximalen Prüfdruck bis 300 bar oder beidem.
ANMERKUNG 1 Diese Verbindungsart wird hauptsächlich an kleinen Gasflaschen (5 l oder weniger) angewendet.
ANMERKUNG 2 In diesem Dokument wird die Einheit Bar verwendet, da sie im Bereich der technischen Gase universell einsetzbar ist. Es sollte jedoch beachtet werden, dass Bar keine SI-Einheit ist und dass die entsprechende SI-Einheit für den Druck Pa ist (1 bar = 105 Pa = 105 N/m2).
Dieses Dokument legt Folgendes fest:
Grundmaße;
Anforderungen an alternative Auslegungen von Bügelventilverschlüssen;
Maße und Anordnungen der Passlöcher und stifte für die Anschlussverbindungen.
Es legt auch die Maße und Anordnungen der Passlöcher und stifte für die Anschlussverbindungen für Gase und Gasgemische fest.
Petites bouteilles à gaz médicaux - Raccords de robinets du type étrier avec ergots de sécurité (ISO 407:2023)
Le présent document s’applique aux raccords de robinet du type étrier avec ergots de sécurité pour bouteilles à gaz médicaux d’une pression de service maximale de 200 bar et/ou d’une pression d’épreuve maximale de 300 bar.
NOTE 1 Ce type de raccord est essentiellement utilisé pour les petites bouteilles (de 5 l ou moins).
NOTE 2 Dans le présent document, l’unité de pression utilisée est le bar, en raison de son usage universel dans le domaine des gaz techniques. Il convient de noter toutefois que cette unité ne fait pas partie du Système international d'unités (SI), et que l'unité SI correspondante pour mesurer la pression est le pascal (Pa, 1 bar = 105 Pa = 105 N/m2).
Le présent document spécifie:
— les dimensions de base des raccords;
— les exigences requises des variantes de construction des raccords de robinets du type étrier;
— les dimensions et positions des trous et des ergots des raccords de sortie.
Il spécifie également les dimensions et les positions des trous et des ergots des sorties de raccords pour les gaz et les mélanges de gaz.
Male plinske jeklenke za uporabo v medicini - Ventilski priključni nastavki po sistemu pin-index (ISO 407:2023)
Ta dokument se uporablja za ventilske priključne nastavke po sistemu pin-index za plinske jeklenke za uporabo v medicini z delovnim tlakom do največ 200 bar ali preskusnim tlakom do največ 300 bar oziroma obojim.
OPOMBA 1: Ta vrsta priključka se uporablja predvsem za male jeklenke (5 l ali manjše).
OPOMBA 2: V tem dokumentu je zaradi splošne uporabe na področju tehničnih plinov uporabljena enota bar. Vendar naj se upošteva, da bar ni enota SI in da je ustrezna enota SI za tlak Pa (1 bar = 105 Pa = 105 N/m2).
Ta dokument določa:
– osnovne mere;
– zahteve za alternativne zasnove ventilskih priključnih nastavkov po sistemu pin-index;
– mere in položaje lukenj in zatičev za izhodne priključke.
Določa tudi mere in položaje lukenj in zatičev za izhodne priključke plinov in njihovih zmesi.

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).
