This document specifies the construction characteristics, performances and marking related to safety and the rational use of energy of portable, flat gas appliances directly supplied at the LPG vapour pressure, incorporating a gas cartridge complying with EN 417:2012, inserted horizontally in the chassis.
NOTE 1   These appliances are referred to in the body of the text as “appliances”.
This document covers appliances for outdoor or in well ventilated areas uses only.
This document does not cover appliances supplied by an external gas source.
For example, the following types of appliances are covered:
a)   cooking appliances (stoves, barbecues);
b)   heating appliances.
This document specifies the requirements applicable to these appliances or their functional sections whether or not the latter are independent or incorporated into an assembly.
Appliances covered by this document are not connected to a flue for the discharge of products of combustion and are not connected to the mains electricity supply.
This document covers neither appliances supplied with LPG in the liquid phase nor appliance with fixed integral container which could be refilled by the user.
This document does not cover appliances of direct pressure propane category.
Requirements for rational use of energy have been considered for stove burners.
NOTE 2   However, such requirements have not been considered for the other types of appliances because:
-   for barbecues, this type of cooking varies according to the type of food and region where the appliance is used;
-   for heating appliances, all the heat produced is discharged into the environment.

Festlegungen für Flüssiggasgeräte - Mit Dampfdruck betriebene Flüssiggasgeräte, die eine waagerechte Kartusche im Gehäuse enthalten

Dieses Dokument legt die Konstruktionsmerkmale, Funktionen und Markierungen in Zusammenhang mit der Sicherheit und der wirtschaftlichen Verwendung von Energie von tragbaren, flachen Gasgeräten fest, die direkt mit LPG-Dampfdruck versorgt werden und über eine integrierte Gaskartusche in Übereinstimmung mit EN 417:2012 verfügen, die horizontal in das Gehäuse eingebaut ist.
ANMERKUNG 1   Diese Geräte werden im gesamten Text als „Geräte“ bezeichnet.
Dieses Dokument ist nur für Geräte anzuwenden, die für die Verwendung im Freien oder in gut belüfteten Bereichen bestimmt sind.
Dieses Dokument ist nicht für Geräte anzuwenden, die von einer externen Gasquelle versorgt werden.
Abgedeckt sind beispielsweise folgende Arten von Geräten:
a)   Kochgeräte (Kocher, Grills);
b)   Heizgeräte.
Dieses Dokument legt die Anforderungen an diese Geräte bzw. deren funktionswichtige Bauteile fest, unabhängig davon, ob letztere separat oder in eine Baugruppe integriert sind.
Durch dieses Dokument sind Geräte abgedeckt, die nicht an Abgasleitungen zur Abführung der Verbrennungsprodukte und nicht an das elektrische Netz angeschlossen sind.
Dieses Dokument bezieht sich weder auf Geräte, die mit Flüssiggas (LPG, en: liquefied petroleum gas) in flüssiger Phase versorgt werden, noch auf Geräte mit fest eingebautem, durch den Anwender nachfüllbarem Gasbehälter.
Dieses Dokument bezieht sich nicht auf Geräte der Kategorie mit unmittelbarem Propandruck.
Die Anforderungen an die wirtschaftliche Nutzung der Energie wurden in Hinblick auf die Brenner der Kocher berücksichtigt.
ANMERKUNG 2   Dagegen wurden derartige Anforderungen nicht für die anderen Gerätearten festgelegt, denn:
—   für Grills ist das Kochergebnis je nach Art der Nahrung und der Region, in der das Gerät eingesetzt wird, unterschiedlich;
—   für Heizgeräte wird die gesamte Wärme auf die Umgebung übertragen.

Spécifications pour les appareils fonctionnant exclusivement aux gaz de pétrole liquéfiés - Appareils GPL à pression de vapeur incorporant une cartouche horizontale dans leur châssis

Le présent document spécifie les caractéristiques de construction, les performances et le marquage relatifs à la sécurité et à l'utilisation rationnelle de l'énergie des appareils plats à gaz portatifs directement alimentés à la pression de vapeur des GPL, comprenant une cartouche de gaz conforme à l'EN 417:2012, insérée horizontalement dans le châssis.
NOTE 1   Ces appareils sont désignés dans l'ensemble du texte par « appareils ».
Le présent document couvre les appareils pour utilisation en plein air ou dans des espaces bien aérés uniquement.
Le présent document ne couvre pas les appareils alimentés par une source de gaz externe.
Sont par exemple visés les types d'appareils suivants :
a)   appareils de cuisson (réchauds, barbecues) ;
b)   appareils de chauffage.
Le present document précise les exigences applicables à tous ces appareils ou éléments fonctionnels, que ces derniers soient indépendants ou incorporés dans un ensemble.
Les appareils couverts par le présent document ne sont pas raccordés à un conduit d'évacuation des produits de la combustion et n'ont pas de raccordement au réseau électrique.
Le présent document ne s'applique ni aux appareils alimentés aux GPL en phase liquide ni à ceux avec réservoir fixe incorporé remplissable par l'utilisateur.
Le présent document ne s'applique pas aux appareils de la catégorie pression directe propane.
Des exigences concernant l'utilisation rationnelle de l'énergie ont été prises en compte pour les brûleurs de réchauds.
NOTE 2   En revanche, de telles exigences n'ont pas été prises en compte pour les autres types d'appareils car :
-   pour les barbecues, ce type de cuisson varie en fonction du type d'aliment et des régions où l'appareil est utilisé ;
-   pour les appareils de chauffage, toute la chaleur produite est transmise dans l'environnement.

This document specifies the construction characteristics, performances and marking related to safety and the

rational use of energy of portable, flat gas appliances directly supplied at the LPG vapour pressure, incorporating

a gas cartridge complying with EN 417:2012, inserted horizontally in the chassis.

NOTE 1 These appliances are referred to in the body of the text as “appliances”.

This document covers appliances for outdoor or in well ventilated areas uses only.

This document does not cover appliances supplied by an external gas source.
For example, the following types of appliances are covered:
a) cooking appliances (stoves, barbecues);
b) heating appliances.

This document specifies the requirements applicable to these appliances or their functional sections whether or

not the latter are independent or incorporated into an assembly.

Appliances covered by this document are not connected to a flue for the discharge of products of combustion and

are not connected to the mains electricity supply.
