Specifications for dedicated liquefied petroleum gas appliances - Portable vapour pressure liquefied petroleum gas appliances

This European Standard specifies the construction and performance characteristics related to safety and the rational use of energy of portable appliances burning liquefied petroleum gases at the vapour pressure within the gas container. It also defines test methods and the requirements for marking and the information to be given in the instructions.
NOTE   These appliances are referred to in the body of the text as "appliances".
This European Standard applies to various types of portable appliances burning liquefied petroleum gases at vapour pressure and designed to be used with (non refillable) cartridges as complying with EN 417 or any types of gas cylinders other than cartridges. For example the following types of appliances are covered:
a)   cooking appliances (hotplates, grills, barbecues...).
This European Standard does not cover barbecues that can be used indoors;
b)   lighting appliances;
c)   heating appliances.
This European Standard only applies to appliances with a maximum heat input of up to 3 kW (Hs) for outdoor use only;
d)   blowlamps.
This European Standard only applies to blowlamps without a flexible hose;
e)   laboratory burners.
The requirements apply to these appliances or their functional sections whether or not the latter are independent or incorporated into an assembly.
This European Standard only applies to type examination.
Appliances covered by this European Standard are not connected to a flue for the discharge of products of combustion and are not connected to the mains electricity supply.
This European Standard covers neither appliances supplied with LPG in the liquid phase nor those incorporating a fixed gas reservoir which may or may not be refilled by the user. This European Standard does not cover gas containers or flexible hose.
It does not apply to smokers’ lighters covered by EN ISO 9994.
Requirements for rational use of energy have been included for hotplate burners.
However, such requirements have not been included for the

Festlegungen für Flüssiggasgeräte - Tragbare, mit Dampfdruck betriebene Flüssiggasgeräte

Die vorliegende Europäische Norm definiert die Konstruktions- und Funktionsmerkmale hinsichtlich Sicherheit und wirtschaftlicher Energienutzung tragbarer Geräte, die Flüssiggase bei Dampfdruck innerhalb des Gasbehälters verbrennen. Sie definiert auch die Prüfverfahren, die Anforderungen zur Kennzeichnung und die Informationen der Gebrauchsanweisung.
ANMERKUNG   Die Geräte werden im gesamten Text als „Geräte“ bezeichnet.
Die vorliegende Europäische Norm bezieht sich auf verschiedene Arten tragbarer Geräte, die Flüssiggase bei Dampfdruck verbrennen, die mit (nicht aufladbaren) Kartuschen entsprechend der Norm EN 417 oder anderen Arten von Gasbehältern betrieben werden. Beispielsweise gehören dazu folgende Geräte:
a)   Kochgeräte (Kocher, Grills, Bratgeräte ...).
Diese Europäische Norm betrifft nicht Bratgeräte für Innenräume;
b)   Leuchtgeräte;
c)   Heizgeräte.
Diese Europäische Norm betrifft nur Heizgeräte mit einer maximalen Wärmebelastung bis zu 3 kW (Hs) und ausschließlich zur Benutzung im Freien;
d)   Lötgeräte.
Nur Lötgeräte ohne Schlauchleitung werden von dieser Europäischen Norm abgedeckt;
e)   Laborbrenner.
Die Anforderungen beziehen sich auf diese Geräte und funktionswichtigen Bauteile, unabhängig davon, ob letztere separat oder eingebaut sind.
Die vorliegende Europäische Norm betrifft nur die Baumusterprüfung.
Durch diese Europäische Norm sind nur Geräte abgedeckt, die nicht an Abgasleitungen zur Abführung der Verbrennungsprodukte und nicht an das elektrische Netz angeschlossen sind.
Diese Europäische Norm bezieht sich weder auf Geräte, die mit Flüssiggas in flüssiger Phase versorgt werden, noch auf solche mit fest eingebauten, durch den Betreiber nachfüllbaren oder nicht nachfüllbaren Gasvorratsbehältern. Diese Norm bezieht sich nicht auf Gasbehälter oder Schlauchleitungen.
Sie ist weiterhin nicht auf die durch die Norm EN ISO 9994 abgedeckten Feuerzeuge anwendbar.
