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 cooking appliances 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, 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.

Diese Europäische Norm gilt für hand-beschickte Feuerstätten, 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 Feuerstätten können entweder feste mineralische Brennstoffe, Torfbriketts, Holzbriketts, Holzscheite 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.

La présente norme est applicable aux appareils domestiques alimentés 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. Ils peuvent utiliser des combustibles minéraux solides, 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.
Štedilniki na trdna goriva - Zahteve in preskusne metode
Ta evropski standard določa zahteve za načrtovanje, proizvodnjo, konstrukcijo, varnost in delovanje
(izkoristek in emisije) ter navodila in označevanje skupaj s preskusnimi metodami in preskusnimi gorivi za preskušanje tipa štedilnikov na trdna goriva. Ta standard se uporablja za naprave, ki se kurijo ročno in se uporabljajo predvsem za kuhanje, njihova dodatna funkcija pa je ogrevanje prostora, v katerem so nameščene. Dodatno pa, kadar so opremljene z vodno komoro, omogočajo pripravo in uporabo sanitarne tople vode in/ali centralno ogrevanje. Te naprave so lahko kurjene s trdnimi mineralnimi gorivi, šotnimi briketi, naravno pridobljenimi ali industrijsko pripravljenimi drvmi ali z več gorivi v skladu z navodili proizvajalca naprave. Ta standard se ne uporablja za naprave z avtomatskim doziranjem goriva ali naprave na mehanski vžig ali za naprave z nameščenimi ventilatorji (vpihovalniki zraka).

The adjusting control shall be clearly visible or shallbe permanently marked so that its operation is readily understandable by the user.The design shall be such that during operation of the appliance, neither ash nor unburnt fuel canprevent the movement or closure of the air inlet control.The ‘cold’ setting of the primary air inlet control shall be clearly marked and the method ofadjustment shall be described in the instructions.The thermostat shall have a variable temperature range and be of the immersion or dry pocket type. The pocket shall be positioned so that the thermostat senses the temperature of the flow water fromthe appliance.4.14.2Secondary air inlet controlWhere a secondary air inlet control is provided the position of air entry shall be so designed that thepassage of air is not restricted when the firebox is filled to the manufacturer's recommended capacity.4.15FluewaysIt shall be possible to clean the flueways of the appliance completely using commercially availabletools or brushes

SIST EN 12815:2003+A1 : 2005
1 Področje uporabe
Ta evropski standard določa zahteve za načrtovanje, proizvodnjo, konstrukcijo, varnost in delovanje
(izkoristek in emisije) ter navodila in označevanje skupaj s preskusnimi metodami in preskusnimi gorivi
za preskušanje tipa štedilnikov na trdna goriva.Ta standard se uporablja za naprave, ki se kurijo ročno in se uporabljajo predvsem za kuhanje, njihova
dodatna funkcija pa je ogrevanje prostora, v katerem so nameščene. Dodatno pa, kadar so opremljene z
vodno komoro, omogočajo pripravo in uporabo sanitarne tople vode in/ali centralno ogrevanje. Te
naprave so lahko kurjene s trdnimi mineralnimi gorivi, šotnimi briketi, naravno pridobljenimi ali
industrijsko pripravljenimi drvmi ali z več gorivi v skladu z navodili proizvajalca naprave.
Ta standard se ne uporablja za naprave z avtomatskim doziranjem goriva ali naprave na mehanski
vžig ali za naprave z nameščenimi ventilatorji (vpihovalniki zraka).2 Zveze s standardi
Ta standard vključuje z datiranim ali nedatiranim sklicevanjem določila iz drugih publikacij. Sklicevanja
na standarde so navedena na ustreznih mestih v besedilu, publikacije pa so naštete spodaj. Pri
datiranih sklicevanjih se pri uporabi tega standarda upoštevajo poznejša dopolnila ali spremembe
katerekoli od navedenih publikacij le, če so z dopolnilom ali spremembo vključene vanj. Pri nedatiranih
sklicevanjih se uporablja zadnja izdaja publikacije (vključno z dopolnili).EN 1561:1997 Livarstvo – Siva litina (z lamelastim grafitom)
