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, B23, B42, B43, B52, B53, C12, C13, C32 and C33 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:
a)   appliances designed for use in domestic dwelling;
b)   outdoor appliances;
c)   appliances of heat input in excess of 120 kW (based on the net calorific value of the appropriate reference test gas);
d)   appliances having fully pre-mixed gas and air burners in which:
1)   either the gas and all the combustion air are brought together just before the level of the combustion zone; or
2)   the pre-mixing of the gas and all combustion air is carried out in a part of the burner upstream of the combustion zone;
e)   appliances that are designed for continuous condensation within the flue system under normal operating conditions;
f)   appliances having combustion products evacuation ducts that are non-metallic.
This standard is applicable to appliances which are intended to be type tested. It also includes requirements concerning the evaluation of conformity, including factory production control, but these requirements only apply to POCEDs and their associated terminals.
NOTE   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.

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
1)   entweder das Gas und die gesamte Verbrennungsluft kurz vor der Verbrennungszone zusammen¬geführt werden; oder
2)   das Vormischen des Gases mit der gesamten Verbrennungsluft in einem Teil des Brenners vor der Verbrennungszone erfolgt;
e)   Geräte, die für kontinuierliche Kondensation im Abgassystem bei normalen Betriebsbedingungen aus¬gelegt sind;
f)   Geräte mit Abgassystem aus nichtmetallenen Werkstoffen.
Diese Norm ist anwendbar für Geräte, die für eine Typprüfung vorgesehen sind.

Tubes radiants suspendus à monobrûleur à usage non-domestique utilisant les combustibles gazeux - Partie 1: Sécurité

La présente Norme européenne définit les exigences et les techniques d'essai relatives à la construction, la
sécurité, la classification et le marquage des tubes radiants suspendus utilisant les combustibles gazeux, à
usage non domestique, comprenant un brûleur unique, équipé d'un système automatique de commande et de
sécurité, appelés ci-après « 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 à être 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 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 brûleur à 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 brûleur en amont
de la zone de combustion ;
e) appareils conçus pour une condensation continue dans le système d'évacuation dans des conditions de
fonctionnement normales ;
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 à subir des essais de type. Elle
comprend également des exigences relatives à l'évaluation de la conformité, y compris le contrôle de
fabrication en usine, mais ces exigences ne s'appliquent uniquement qu’aux conduits d'évacuation des
produits de combustion et aux terminaux associés.
