Residential independent boilers fired by solid fuel - Nominal heat output up to 50 kW - Requirements and test methods
This European Standard specifies requirements relating to the design, manufacture, construction, performance (efficiency and emission), safety, instructions and marking together with associated test methods and test fuels for type testing residential independent boilers fired by solid fuel.
This standard is applicable to hand and automatically fired appliances having nominal heat outputs up to 50 kW, the primary function of which is to provide hot water for central heating and/or domestic use, and which are designed for use only with open vented systems at a working pressure not exceeding 2 bar. In addition to their primary function of providing hot water these appliances also provide space heating to the place of installation. 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 independent boilers for hot water only production and having heat outputs of less than 5 kW.
This standard is also not applicable to the design and construction of automatic stoking devices.
Heizkessel für feste Brennstoffe - Nennwärmeleistung bis 50 kW - 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 häuslichen Herden für feste Brennstoffe. Diese Norm gilt für hand- und automatisch beschickte Feuerstätten bis zu einer Nennwärmeleistung von 50 kW, deren Hauptfunktion die Erwärmung von Heiz- und Brauchwasser ist und die ausschließlich für den Einbau in offene Systeme mit einem Arbeitsdruck von höchstens 2 bar verwendet werden. Außer ihrer Hauptfunktion der Erwärmung von Heiz- und Brauchwasser ist die Feuerstätte auch für die Beheizung des Aufstellungsraumes vorgesehen. Diese Feuerstätten können entweder feste mineralische Brennstoffe, Torfbriketts, Holzbriketts, Holzscheite oder mehrere dieser Brennstoffe nach Anleitung des Feuerstättenherstellers verfeuern. Diese Norm gilt für Heizkessel, die nur Heiz- und Brauchwasser erwärmen, und solche mit einer Nennwärmeleistung von weniger als 5 kW. Diese Norm gilt nicht für die Auslegung und Ausführung von automatischen Fördersystemen.
Chaudières domestiques à combustible solide destinées à être implantées dans le volume habitable - Puissance calorifique nominale inférieure ou égale à 50 kW - Exigences et méthodes d'essai
La présente Norme européenne spécifie les exigences relatives aux instructions de conception, fabrication, construction, performance (rendement et émission), sécurité ainsi que les méthodes et combustibles d'essai correspondants pour les essais de type des chaudières domestiques à combustible solide destinées à être implantées dans le volume habitable.
La présente norme s’applique aux appareils de chauffage à alimentation manuelle et automatique à puissances calorifiques nominales jusqu’à 50 kW, dont la fonction principale est de fournir de l’eau chaude à des fins de chauffage central et/ou pour usage domestique. Ils ne sont conçus que pour être utilisés avec des systèmes à expansion ouverts à une pression de service ne dépassant pas 2 bars. Outre leur fonction principale de fournir de l’eau chaude, ces appareils fournissent également de la chaleur dans l'espace où ils sont installés. Ces appareils peuvent fonctionner avec des combustibles minéraux solides, des briquettes de tourbe, des bûches de bois naturelles ou manufacturées ; ils peuvent également fonctionner avec plusieurs combustibles conformément aux instructions du fabricant de l'appareil.
La présente norme ne s’applique pas aux bouilleurs indépendants uniquement destinés à la production d’eau chaude à puissances calorifiques inférieures à 5 kW.
La présente norme ne s’applique également pas à la conception et à la construction des dispositifs à chargement automatiques.
