Automatic burner control systems for burners and appliances burning gaseous or liquid fuels
This European Standard specifies the safety, construction and performance requirements for automatic burner control systems, programming units and flame detector devices, intended for for similar usages, with gas and oil burners and gas and oil burning appliances, with or without fans. These devices are hereafter referred to generally as "automatic burner control systems”.
This European Standard is applicable to automatic burner control systems that include additional functions.
This European Standard does not cover automatic burner control systems utilizing thermo-electric flame supervision devices.
NOTE 1 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.
NOTE 2 Provisions for production control are not part of this European Standard.

Cette Norme européenne spécifie les exigences de sécurité, de construction et de fonctionnement, la
technique des essais et le marquage des systèmes automatiques de commande des brûleurs, des unités de
programmation ainsi que des dispositifs de détection de flamme pour les brûleurs et les appareils à gaz et à
fioul, avec ou sans ventilateur.
Le présent document est applicable aux systèmes automatiques de commande des brûleurs, comportant des
fonctions additionnelles.
La présente norme ne concerne pas les systèmes automatiques de commande des brûleurs utilisant des
dispositifs de détection de flamme thermoélectriques.
NOTE 1 Les normes européennes pour brûleurs, appareils ou processus qui mettent en oeuvre des systèmes
automatiques de commande des brûleurs, des unités de programmation ou des dispositifs de détection de flamme,
peuvent être considérées comme prioritaires par rapport à la présente norme.
NOTE 2 Les dispositions pour le contrôle de la production ne font pas partie de la présente Norme européenne.

Alignment with EN 13611:2007+A2:2011; Integration of the requirements from EN 230 (EN 230 is merged into prEN 298); NOTE
If, due to the reference of EN 13611 the term “gas” will be part of a requirement or test, then the term “gas” shall be substituted by the term “fuel”
Requirements from the flame supervision and the reactions in case of loss of flame have been adapted to modifications made in EN 267 and EN 676 and optimised for better understanding; Requirements and tests for “independent flame detectors” have been integrated; New requirements concerning “common cause” have been added; Requirements for the new function “remote reset from lock-out” have been added. EN 298 compliance for burner control systems or flame detector devices cannot be claimed based upon SIL classification according to EN 61508. SIL classification cannot be claimed based upon compliance with this standard only. A supplementary method for SIL determination is specified in EN 13611:2007+A2:2011, Annex J. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, SIST EN 298:2012
