a) low gas pressure appliances operating at pressures up to and including 50 mbar;
b) medium gas pressure appliances operating at pressures above 50 mbar and up to 2 bar.
This European Standard is not applicable to:
- appliances designed for use in domestic dwellings;
- outdoor appliances;
- appliances of heat input in excess of 120 kW (based on the net calorific value of the appropriate reference gas);
This standard is applicable to appliances which are intended to be type tested.

Dieses Dokument legt die Anforderungen und Prüfverfahren im Hinblick auf die Konstruktion, Sicherheit, rationelle Energienutzung, Klassifizierung und Kennzeichnung gasbefeuerter Hellstrahler für gewerbliche und industrielle Anwendung (im folgenden Text als „Geräte“ bezeichnet) fest.
Dieses Dokument gilt nur für Geräte der Typen A1 und A3 (siehe 4.2.2) für die Anwendung in Räumlichkeiten, die keine Wohnungen sind:
a) Niederdruckgeräte mit Betriebsdrücken bis einschließlich 50 mbar;
b) für Mitteldruckgeräte mit Betriebsdrücken über 50 mbar bis zu 2 bar.
Dieses Dokument gilt nicht für:
- Geräte, die für eine Verwendung in Wohnungen gedacht sind;
- Geräte, die für eine Verwendung im Freien gedacht sind;
- Geräte mit einer Wärmebelastung über 120 kW (bezogen auf den Heizwert des jeweiligen Normprüfgases).
Dieses Dokument ist anwendbar für Geräte, die für eine Typprüfung vorgesehen sind.
Appareils surélevés de chauffage à rayonnement lumineux au gaz à usage non domestique - Sécurité et efficacité énergétique
La présente Norme européenne définit les exigences et les techniques d’essai relatives à la construction, la sécurité, l’utilisation rationnelle de l’énergie, la classification et le marquage des appareils surélevés de chauffage à rayonnement lumineux au gaz à usage non domestique pour le confort ambiant, appelés ci-après « appareils ».
La présente Norme européenne s’applique aux appareils de type A1 et de type A3 (voir 4.2.2) destinés à être utilisés ailleurs que dans les locaux résidentiels :
a) appareils à gaz basse pression fonctionnant à des pressions inférieures ou égales à 50 mbar ;
b) appareils à gaz moyenne pression fonctionnant à des pressions comprises entre 50 mbar et 2 bar.
La présente Norme européenne ne s’applique pas :
- aux appareils conçus pour des locaux domestiques ;
- aux appareils utilisés en plein air ;
- aux appareils dont le débit calorifique dépasse 120 kW (sur le pouvoir calorifique inférieur du gaz de référence approprié).
La présente norme s’applique aux appareils qui sont destinés à subir des essais de type.
Stropna plinska sevala z zgorevanjem na površini za gretje nestanovanjskih prostorov - Varnost in energijska učinkovitost
Ta evropski standard določa zahteve in preskusne metode za izdelavo, varnost, racionalno rabo energije, razvrščanje in označevanje stropnih plinskih seval z zgorevanjem na površini za gretje nestanovanjskih prostorov (v telesu besedila imenovanih »aparati«).
Ta evropski standard se uporablja samo za aparate tipa A1 in tipa A3 (glej 4.2.2), ki so namenjeni za uporabo v nestanovanjskih prostorih:
a) aparate z nizkim tlakom plina, ki delujejo pri tlakih do vključno 50 mbar;
b) aparate s srednjim tlakom plina, ki delujejo pri tlakih nad 50 mbar do vključno 2 mbar.
Ta evropski standard se ne uporablja za:
– aparate, zasnovane za uporabo v stanovanjskih prostorih;
– aparate za uporabo na prostem;
– aparate, pri katerih nazivna moč presega 120 kW (na podlagi neto kalorične vrednosti ustreznega referenčnega preskusnega plina).
Ta standard se uporablja za aparate, predvidene za tipski preskus.
