Automatic gas burner control systems for gas burners and gas burning appliances with or without fans
This European Standard specifies requirements for the construction and function, test methods and marking of automatic burner control systems and also programming units and their associated flame detector devices for gas burners and gas burning appliances with or without fans.
This standard also applies to automatic burner control systems, programming units and their associated flame detector devices that include additional functions.
Automatic burner control systems utilizing thermo-electric flame supervision devices are not covered by this standard.
This European Standard covers type testing only.
NOTE European Standards for burners, appliances or processes which use automatic burner control systems, programming units or flame detectors can override the requirements of this standard.
Feuerungsautomaten für Gasbrenner und Gasgeräte mit oder ohne Gebläse
Diese Europäische Norm legt Anforderungen an den Bau und die Funktion, an Prüfverfahren und die Kennzeichnung von Feuerungsautomaten sowie von Steuergeräten und den zugehörigen Flammenwächtern für Gasbrenner und Gasgeräte mit oder ohne Gebläse fest.
Diese Norm gilt auch für Feuerungsautomaten, Steuergeräte und die zugehörigen Flammenwächter, die zusätzliche Funktionen enthalten.
Feuerungsautomaten, die thermoelektrische Flammenüberwachungseinrichtungen verwenden, sind nicht Gegenstand dieser Norm.
In dieser Norm wird nur die Typprüfung behandelt.
ANMERKUNG Europäische Normen für Brenner, Geräte oder Prozesse, die Feuerungsautomaten, Steuergeräte oder Flammenwächter verwenden, können dieser Norm vorgezogen werden.
Systèmes automatiques de commande et de sécurité pour brûleurs et appareils avec ou sans ventilateur utilisant les combustibles gazeux
La présente Norme Européenne a pour objet de fixer les exigences concernant les caractéristiques de construction et de fonctionnement, la technique des essais et le marquage des systèmes de commande et de sécurité pour brûleurs automatiques et vise également les dispositifs de commande avec les dispositifs de détection de flamme qui leur sont associés, pour les brûleurs et les appareils avec ou sans ventilateur.
