Residential cookers fired by solid fuel - Requirements and test methods
This European Standard specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emission), instructions and marking together with associated test methods and test fuels for type testing residential coking apliances fired by solid fuel.
This standard is applicable to hand fired appliances whose primary function is to cook and whose secondary function is to provide heat into the space in which they are installed. Additionally, where fitted with a boiler they also provide domestic hot water and/or central heating. These appliances may burn either solid mineral fuels, peat briquettes or natural or manufactured wood logs or be multi-fuel in accordance with the appliance manufacturer’s instructions.
This standard is not applicable to hopper fed or mechanically fired appliances or those appliances having fan assisted combustion air.
Herde für feste Brennstoffe - Anforderungen und Prüfung
Diese Europäische Norm gilt für handbeschickte Herde, deren Hauptfunktion das Kochen und deren weitere Funktion die Beheizung des Aufstellungsraumes ist. Heizungsherde liefern auch erwärmtes Brauchwasser und/oder erwärmtes Wasser für zentrale Heizungsanlagen.
Diese Europäische Norm legt Anforderungen an Auslegung, Herstellung, Ausführung, Sicherheit und Leistungsvermögen (Wirkungsgrad und Emission) von Herden fest, die mit festen Brennstoffen befeuert werden (nachfolgend „Herd(e)“ genannt), und enthält diesbezügliche Anweisungen. Des Weiteren enthält sie Festlegungen für eine Konformitätsprüfung (z. B. Erstprüfung und werkseigene Produktionskontrolle) sowie für die Kennzeichnung dieser Produkte.
Diese Feuerstätten können entweder feste mineralische Brennstoffe, Braunkohlebriketts, Torfbriketts, Holzbriketts, Scheitholz oder mehrere dieser Brennstoffe nach Anleitung des Feuerstätten-Herstellers verfeuern.
Diese Norm gilt nicht für Feuerstätten, die aus einem Vorratsbehälter beschickt, mechanisch betrieben werden oder ein Verbrennungsluftgebläse haben.
Cuisiniéres domestiques à combustible solide - Exigences et méthodes d'essai
La présente norme est applicable aux cuisinières domestiques alimentées manuellement dont la fonction
principale est de cuire et la fonction secondaire de chauffer l’espace environnant. En plus, lorsqu’ils sont
équipés d’une chaudière, ces appareils fournissent de l’eau chaude et/ou assurent le chauffage central.
La présente Norme européenne spécifie les exigences relatives aux instructions de conception, fabrication,
construction, sécurité, performance (rendement et émission) des cuisinières domestiques à combustible
solide destinées à être implantées dans le volume habitable (ci-après désigné par les « appareils » et fournit
les instructions les concernant. En outre, elle fournit également des dispositions concernant l'évaluation de la
conformité (à savoir l’essai de type initial (ITT) et du contrôle de la production en usine et le marquage de ces
produits.
Ils peuvent utiliser des combustibles minéraux solides, des briquettes de lignite, des briquettes de tourbe, de
bûches de bois naturel ou manufacturé ou plusieurs combustibles conformément aux instructions du fabricant.
La présente norme ne s’applique pas aux appareils alimentés par trémie ou allumés mécaniquement ni aux
appareils équipés d’un ventilateur pour l’alimentation en air de combustion.

1 Scope
This European Standard is applicable to hand fired residential cookers whose primary function is to
cook and whose secondary function is to provide heat into the space in which they are installed.
Additionally, where fitted with a boiler, they also provide domestic hot water and/or central heating.
This European Standard specifies requirements relating to the design, manufacture, construction,
safety and performance (efficiency and emission) of residential cookers fired by solid fuel (hereafter
referred to as “appliance(s)”) and provides instructions for them. Furthermore, it also gives provisions
for evaluation of conformity (i.e. initial type testing (ITT) and factory production control (FPC) and
marking of these products.
These appliances may burn either solid mineral fuels, lignite briquettes, peat briquettes, natural or
manufactured wood logs or be multi-fuel in accordance with the appliance manufacturer's instructions.
This standard is not applicable to hopper fed or mechanically fired appliances or those appliances
having fan assisted combustion air.
