(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.
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.
