Roomheaters 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 roomheaters fired by solid fuel.
This Standard is applicable to non-mechanically fired appliances which are listed under categories 1a and 2a of Table 1. These appliances provide heat into the space where 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, natural or manufactured wood logs or be multi-fuel in accordance with the appliance manufacturer's instructions.
This standard is not applicable to appliances with fan assisted combustion air.

Raumheizer für feste Brennstoffe - Anforderungen und Prüfung

Diese Europäische Norm beschreibt Anforderungen an Auslegung, Herstellung, Ausführung, Sicherheit und Leistungsvermögen (Wirkungsgrad und Emission), Anleitung und Kennzeichnung zusammen mit zugehörigen Prüfverfahren und Prüfbrennstoffen für die Typprüfung von Raumheizern für feste Brennstoffe.
Diese Norm gilt für nicht mechanisch beschickte Feuerstätten, die in Tabelle 1, Kategorie 1a) und 2a), aufgeführt sind. Diese Feuerstätten beheizen den Aufstellungsraum. Sofern sie mit wasserführenden Bauteilen ausgestattet sind, beheizen sie auch Heizwasser und/oder Brauchwasser. Diese Feuerstätten können entsprechend der Bedienungsanleitung des Herstellers entweder feste mineralische Brennstoffe, Torfbriketts, Holzscheite, Holzbriketts oder mehrere dieser Brennstoffe verfeuern. Diese Norm gilt nicht für Feuerstätten mit Verbrennungsluftgebläse.ANMERKUNG   Ohne funktionale Änderung bedeutet eine Veränderung der Verkleidung der Feuerstätte, die die Wärmeabgabe verändert, die Verbrennung jedoch nicht beeinflusst.

Poêles à combustible solide - Exigences et méthodes d'essai

La présente Norme européenne définit les exigences relatives à la conception, à la fabrication, à l'assemblage, à la sécurité, aux performances (rendement et émissions), aux instructions et au marquage ainsi que les méthodes d'essais et combustibles d'essais correspondants pour les essais des poêles domestiques à combustible solide.
La présente norme est applicable aux appareils dépourvus d'alimentation mécanique et qui sont repris sous les catégories 1a et 2a du Tableau 1. Ces appareils produisent de la chaleur dans l'espace où ils sont installés. De plus, lorsqu'ils sont équipés d'un bouilleur, ils produisent également de l'eau chaude à usage domestique et/ou du chauffage central. Ces appareils peuvent utiliser soit des combustibles minéraux solides, des briquettes de tourbe, des bûches de bois naturel ou reconstitué, soit plusieurs combustibles conformément aux instructions du fabricant.
Cette norme ne s'applique pas aux appareils équipés d'un ventilateur pour l'alimentation en air de combustion.
