(Main)Gas tightness of equipment for gas welding and allied processes (ISO 9090:2019)
Gas tightness of equipment for gas welding and allied processes (ISO 9090:2019)
This document specifies the maximum external gas leakage rates which are acceptable for equipment used for welding, cutting and allied processes and provides the procedures of measurement.
It applies to individual components which are used in the gas supply to a blowpipe from the connecting point of the hose (outlet of the cylinder valve or connecting point to a gas supply plant). It does not apply to gas supply plant.
NOTE Specific requirements on the test method and conditions/procedure for measurement of the maximum external leakages can be given in individual standards, e.g. ISO 9012 for air-aspirated hand blowpipes. Concerning the method and the conditions to be applied, the individual standard takes precedence over this document. The maximum external leakages according to this document apply.
Gasdichtheit von Geräten für Gasschweißen und verwandte Verfahren (ISO 9090:2019)
Dieses Dokument legt die maximalen äußeren Gasleckraten fest, die für Geräte für Gasschweißen, Schneiden und verwandte Verfahren zulässig sind und nennt die Verfahren zur Messung.
Es gilt für einzelne Teile, die von der Gasversorgung bis zum Brenner ab Verbindungspunkt des Schlauches (Abgang des Flaschenventils oder Verbindungspunkt der Gasversorgungsanlage) verwendet werden. Es gilt nicht für Gasversorgungsanlagen selbst.
ANMERKUNG Spezifische Anforderungen an die Prüfverfahren und Randbedingungen/ Vorgehensweise zur Messung der maximalen äußeren Leckagen können in separaten Normen angegeben sein, z. B. in ISO 9012 für Handbrenner für angesaugte Luft. Im Hinblick auf das Verfahren und die Randbedingungen, die eingehalten werden müssen, hat die jeweilige Norm Vorrang vor diesem Dokument. Es gelten die maximalen äußeren Leckagen nach diesem Dokument.
Étanchéité aux gaz des appareils pour soudage aux gaz et techniques connexes (ISO 9090:2019)
Le présent document spécifie les niveaux de fuite de gaz externe maximale admissible pour les appareils utilisés pour le soudage, le coupage et les techniques connexes et fournit des méthodes de mesure.
Il s'applique aux composants individuels utilisés pour alimenter un chalumeau, à partir du point de raccordement du tuyau (sortie du robinet de la bouteille ou point de raccordement à une installation de distribution de gaz). Il ne s'applique pas aux installations de distribution de gaz.
NOTE Des exigences spécifiques sur la méthode d'essai et les conditions/procédure de mesure des fuites externes maximales peuvent être données dans les normes, e.g. l'ISO 9012 pour les chalumeaux manuels aéro-gaz à air aspiré. Au sujet de la méthode et des conditions à appliquer, la norme prend le dessus sur le présent document. Les fuites externes maximales selon le présent document s'appliquent.
Tesnost opreme za plamensko varjenje in sorodne postopke (ISO 9090:2019)
Ta dokument določa maksimalne stopnje puščanja zunanjega plina, sprejemljive za opremo, ki se uporablja pri varjenju, rezanju in sorodnih postopkih, ter navaja postopke merjenja. Uporablja se za posamezne komponente, ki se uporabljajo pri dovodu plina do gorilnikov od točke povezovanja cevi (izhod ventila za jeklenke ali točka povezovanja z obratom za dovod plina). Ne uporablja se za obrat za dovod plina.

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

revised. The main changes compared to the previous edition are as follows:
— the Scope has been clarified;
— Clause 2 has been updated;
— a leakage requirement for unconnected female elements of a quick-action coupling has been added;
— the term “hose” has been replaced by “hose assembly” and the value for the leakage has been added;
— various types of blowpipes have been covered;
— in 6.2.1, b) the lower test pressure has been updated;
— the test methods for blowpipes have been moved to new Annex B;
— hydrogen is not allowed anymore for leakage test; Table A.1 has been updated accordingly.
