Safety and control devices for burners and appliances burning gaseous or liquid fuels - Control functions in electronic systems - Methods for classification and assessment

This European Standard specifies methods for the classification and assessment of function blocks designed to operate burners and appliances burning gaseous or liquid fuels with particular regards to their fault behaviour and preventative measures.
This European Standard is applicable to control function blocks, not covered by a dedicated control standard (e.g. EN 88-1:2011, EN 88-2:2007, EN 125:2010, EN 126:2012, EN 126:2012/prA1:2014, EN 161:2011+A3:2013, EN 257:2010, EN 298:2012, EN 1106:2010, EN 1643:2014, EN 1854:2010, EN 12067-2:2004, EN 16304:2013 and EN 16340:2014, EN ISO 23553-1:2014).

Sicherheits- und Regeleinrichtungen für Brenner und Brennstoffgeräte für gasförmige oder flüssige Brennstoffe - Regel- und Steuerfunktionen in elektronischen Systemen - Verfahren für die Klassifizierung und Bewertung

Diese Europäische Norm legt Verfahren für die Klassifizierung und Bewertung von Funktionsblöcken fest, insbesondere hinsichtlich ihres Fehlerverhaltens und der Schutzmaßnahmen, die für den Betrieb von Brennern und Brennstoffgeräten für gasförmige oder flüssige Brennstoffe vorgesehen sind.
Diese Europäische Norm gilt für Regel- und Steuerfunktionsblöcke, die nicht in einer eigenständigen Norm zu Regel- und Steuereinrichtungen behandelt werden (z. B. EN 88-1:2011, EN 88-2:2007, EN 125:2010, EN 126:2012, EN 126:2012/prA1:2014, EN 161:2011+A3:2013, EN 257:2010, EN 298:2012, EN 1106:2010, EN 1643:2014, EN 1854:2010, EN 12067-2:2004, EN 16304:2013 und EN 16340:2014, EN ISO 23553-1:2014).

Dispositifs de commande et de sécurité pour brûleurs et appareils utilisant des combustibles gazeux ou liquides - Fonctions de commande des systèmes électroniques - Méthodes de classification et d’évaluation

La présente Norme européenne spécifie des méthodes pour la classification et l’évaluation des blocs de fonction de commande des brûleurs et des appareils à combustibles gazeux ou liquides, en particulier en ce qui concerne leur comportement au défaut et les mesures préventives.
La présente Norme européenne est applicable aux blocs de fonction de commande qui ne sont pas couverts par des normes de dispositifs particulières (par exemple EN 88-1:2011, EN 88-2:2007, EN 125:2010, EN 126:2012, EN 126:2012/prA1:2014, EN 161:2011+A3:2013, EN 257:2010, EN 298:2012, EN 1106:2010, EN 1643:2014, EN 1854:2010, EN 12067-2:2004, EN 16304:2013 et EN 16340:2014, EN ISO 23553 1:2014).

Varnostne in nadzorne naprave za gorilnike in aparate na plin ali tekoča goriva - Regulacijske in nadzorne funkcije v elektronskih sistemih - Metode za razvrščanje in ocenjevanje

Ta evropski standard določa metode za razvrščanje in ocenjevanje funkcijskih blokov, namenjenih za upravljanje gorilnikov in aparatov na plin ali tekoča goriva, zlasti glede njihovega odziva na napake in preventivnih ukrepov. Ta evropski standard velja za nadzorne funkcijske bloke, ki jih ne zajema namenski nadzorni standard (npr. EN 88-1:2011, EN 88-2:2007, EN 125:2010, EN 126:2004, EN 161:2011, EN 257:2010, EN 298:2003, EN 1106:2010, EN 1643:2000, EN 1854:2010, EN 12067-2:2004, prEN 16304:2011 in prEN 16340:2011, EN ISO 23553-1:2009).
