Single burner gas-fired overhead radiant tube heaters for non-domestic use - Part 1: Safety
Single burner gas-fired overhead radiant tube heaters for non-domestic use - Part 1: Safety
This European Standard specifies the requirements and test methods for the construction, safety, classification and marking of non-domestic gas fired overhead radiant tube heaters incorporating a single burner system under the control of an automatic burner control system, referred to in the body of the text as 'appliances'. This standard is applicable to Type A2, A3, B12, B13, B22 and B23 appliances intended for use in other than domestic dwellings, in which the supply of combustion air and/or the evacuation of the products of combustion is achieved by mechanical means located upstream of the draught diverter, if provided. This standard is not applicable to: - appliances designed for use in domestic dwelling; - outdoor appliances; - appliances of heat input in excess of 120 kW (based on the net calorific value of the appropriate reference test gas); - appliances having fully pre-mixed gas and air burners in which: - either the gas and all the combustion air are brought together just before the level of the combustion zone; - or the pre-mixing of the gas and all combustion air is carried out in a part of the burner upstream of the combustion zone. This standard is applicable to appliances which are intended to by type tested. Requirements for appliances which are not intended to be type tested would need to be subject to further consideration. Requirements concerning the rational use of energy have not been included in this European Standard.
Gasgeräte-Heizstrahler - Dunkelstrahler mit einem Brenner mit Gebläse für gewerbliche und industrielle Anwendung - Teil 1: Sicherheit
Diese Norm behandelt die Anforderungen und die Prüfmethoden im Hinblick auf die Konstruktion, die Sicherheit, die Gebrauchstauglichkeit sowie die Klassifizierung und die Kennzeichnung für Dunkelstrahler mit einem Brenner mit Gebläse für gewerbliche und industrielle Anwendung mit Überwachung durch einen Gasfeuerungsautomaten (im folgenden Text als "Geräte" bezeichnet).
Diese Europäische Norm gilt für Geräte der Arten A2, A3, B12, B13, B22, B23, B42, B43, B52, B53, C12, C13, C32 und C33, die für gewerbliche und industrielle Anwendung vorgesehen sind und bei denen die Zufuhr der Verbrennungsluft und/oder die Abführung der Verbrennungsprodukte mit mechanischen Mitteln erfolgt, die vor der Strömungssicherung angeordnet sind, wenn eine solche vorgesehen ist.
Diese Norm ist anwendbar für Geräte, die für eine Typprüfung vorgesehen sind. Anforderungen an Geräte, die nicht für eine Typprüfung vorgesehen sind, benötigen weitere Überlegungen.
Diese Europäische Norm gilt nicht für:
a) Geräte, die für eine Verwendung in Wohnungen gedacht sind;
b) Geräte, die für eine Verwendung im Freien gedacht sind;
c) Geräte mit einer Wärmebelastung über 120 kW (bezogen auf den Heizwert des jeweiligen Normprüf¬gases);
d) Geräte mit Brennern mit kompletter Gas- und Luftvormischung, bei denen
- entweder das Gas und die gesamte Verbrennungsluft kurz vor der Verbrennungszone zusammengeführt werden; oder
- das Vormischen des Gases mit der gesamten Verbrennungsluft in einem Teil des Brenners vor der Verbrennungszone erfolgt; Geräte die für kontinuierliche Kondensation im Abgassystem bei normalen Betriebsbedingungen ausgelegt sind;
e) Geräte mit Abgassystem aus nichtmetallenen Werkstoffen;
f) Geräte mit Abgassystem aus nichtmetallenen Werkstoffen.
Diese Norm ist anwendbar für Geräte, die für eine Typprüfung vorgesehen sind. Sie enthält auch Anforderungen an die Entwicklung von Übereinstimmung einschließlich Fertigungskontrolle, aber diese Anforderungen gelten nur für (...)

La présente norme européenne définit les exigences et les techniques d'essai relatives a la construction, la sécurité, la classification et le marquage des tubes radiants suspendus utilisant les combustibles gazeux, a usage non domestique, comprenant un bruleur unique, équipé d'un systeme automatique de commande et de sécurité, appelés ci-apres « appareils ».
La présente norme européenne est applicable aux appareils de type A2, A3, B12, B13, B22, B23, B42, B43, B52, B53, C12, C13, C32 et C33, destinés a etre utilisés ailleurs que dans des locaux d’habitation domestiques pour lesquels l’alimentation en air comburant et/ou l'évacuation des produits de combustion est assurée par des moyens mécaniques situés, le cas échéant, en amont du coupe tirage.
La présente norme européenne est applicable aux appareils qui sont destinés a subir des essais de type. Les exigences relatives aux appareils qui ne sont pas destinés a subir des essais de type nécessiteraient une attention particuliere.
La présente norme européenne ne s'applique pas :
a) aux appareils conçus pour des locaux domestiques ;
b) aux appareils utilisés en plein air ;
c) aux appareils dont le débit calorifique dépasse 120 kW (sur le pouvoir calorifique inférieur du gaz de référence approprié) ;
d) aux appareils avec bruleur a prémélange total dans lesquels :
1) le gaz et tout l'air comburant sont mélangés juste avant la zone de combustion ou
2) le prémélange du gaz et de tout l'air comburant est transporté dans une partie du bruleur en amont de la zone de combustion. « - appareils conçus pour une condensation continue dans le systeme d'évacuation dans des conditions de fonctionnement normales » ;
e) aux appareils équipés de conduits d'évacuation des produits de combustion non métalliques .
f) aux appareils équipés de conduits d'évacuation des produits de combustion non métalliques .
La présente norme européenne est applicable aux appareils qui sont destinés a subir des essais de type.
