Automatic shut-off valves for gas burners and gas appliances
This European standard specifies the safety, construction and performance requirements for automatic shut-off valves for gas burners, gas appliances and similar use, hereafter referred to as valves.
This European Standard covers type testing only.
It applies to valves with declared maximum working pressures up to and including 4 bar, for use on burners or in appliances using fuel gases of the 1st, 2nd or 3rd families.
It applies to electrically operated valves and to valves actuated by fluids where the control valves for these fluids are actuated electrically, but not to any external electrical devices for switching the control signal or actuating energy.
It applies to valves where the flow rate is controlled by external electrical signals, either in discrete steps or proportional to the applied signal.
It applies to valves fitted with closed position indicator switches.
Automatische Absperrventile für Gasbrenner und Gasgeräte
Diese Europäische Norm legt Anforderungen an die Sicherheit sowie Bau- und Betriebsanforderungen an automa-tische Absperrventile für Gasbrenner, Gasgeräte und ähnliche Anwendungen, nachstehend Ventile genannt, fest.
Diese Europäische Norm bezieht sich nur auf die Baumusterprüfung.
Sie gilt für Ventile für zulässige Betriebsdrücke bis einschließlich 4 bar zur Verwendung an Gasbrennern oder in Gasgeräten, die für ein oder mehrere Brenngase der ersten, zweiten oder dritten Gasfamilie ausgelegt sind.
Sie gilt für elektrisch betriebene Ventile und für Ventile, die durch Steuermedien angesteuert werden, wenn die Steuerventile für diese Medien elektrisch geschaltet werden. Externe, elektrische Schalter, die das Steuersignal oder die Stellantriebsenergie beeinflussen, werden von der vorliegenden Norm nicht behandelt.
Diese Norm gilt für Ventile, bei denen die Durchflussmenge durch externe elektrische Signale entweder in Stufen oder proportional zum angelegten Signal geregelt wird.
Sie gilt für Ventile mit Schaltern, die die geschlossene Stellung anzeigen.
Robinets automatiques de sectionnement pour bruleurs a gaz et appareils a gaz
La présente Norme européenne spécifie les exigences de sécurité, de construction et de fonctionnement des robinets automatiques de sectionnement pour brûleur à gaz et appareils à gaz, dénommés ci-après "robinets".
La présente Norme européenne couvre uniquement les essais de type.
Elle s'applique aux robinets dont la pression de service maximale est jusqu'à 4 bar destinés à équiper des brûleurs ou des appareils qui peuvent être alimentés avec un ou plusieurs des gaz de la 1ère, de la 2ème ou de la 3ème famille.
Elle s'applique aux robinets de sectionnement commandés électriquement et aux robinets de sectionnement actionnés par des fluides si les vannes de ces fluides sont commandées électriquement mais non à aucun dispositif électrique, placé à l'extérieur du robinet qui donne le signal de commande ou libère l'énergie motrice de commande.
Elle s'applique aux robinets par lesquels le débit est contrôlé par des signaux électriques externes, soit par allures, soit proportionnellement au signal reçu.
Elle s'applique aux robinets équipés de contacts indicateurs de position de fermeture.
