Specification for dedicated liquefied petroleum gas appliances - Barbecues for outdoor use contact grills included

This European Standard specifies the constructional and performance characteristics, safety specifications, relevant test methods and marking of barbecues burning liquefied petroleum gas, referred to in the body of the text as "appliances".
This European Standard covers barbecues as defined in 3.6 and contact grills as defined in 3.8, used outdoors and operating with the gases indicated in 4.1 according to the categories indicated in 4.2. They are fitted with at least one cooking device.
This European Standard applies to these appliances and their functional sections whether or not the latter are independent or incorporated into an assembly.
This European Standard also applies to appliances designed to be built-in.
This European Standard only applies to type testing.
Appliances supplied with third family gas at pressures greater those defined in 4.2 are outside the field of application of this European Standard.
During the consideration of this text, it was apparent that the concept of thermal efficiency with regard to appliances such as barbecues was not appropriate.
This is because:
-   during cooking, there is an additional transfer of heat due to the meat juices falling onto the refractories;
-   there is no relation between the item to be cooked and the useful area;
-   the barbecue is an outdoor appliance in which the action of the wind is important in relation to efficiency.
In consequence there is no specific requirement covering thermal efficiency for this type of appliance.
This European Standard does not state all applicable requirements for integral equipments of other nature (for example burners covered by EN 484).

Festlegungen für Flüssiggasgeräte - Grillgeräte zur Verwendung im Freien einschließlich Kontaktgrillgeräte

Diese Europäische Norm legt die konstruktiven und funktionellen Eigenschaften, die
Sicherheitsanforderungen, die anzuwendenden Prüfverfahren und die Kennzeichnung von Flüssiggas
betriebenen Grillgeräten fest, welche im Hauptteil des Textes als „Geräte“ bezeichnet werden.
Diese Europäische Norm gilt für die in 3.6 beschriebenen Grillgeräte und in 3.8 beschriebenen
Kontaktgrillgeräte zur Verwendung im Freien und für den Betrieb mit den in 4.1 aufgeführten Gasen, abhängig
von der in 4.2 festgelegten Kategorie. Sie sind mit mindestens einem Kochzubehör ausgestattet.
Diese Europäische Norm gilt für diese Geräte und deren funktionale Bauteile, unabhängig davon, ob diese
allein verwendet werden oder in eine Kombination eingebaut sind.
Diese Europäische Norm gilt auch für Geräte, die als Einbaugeräte vorgesehen sind.
Diese Europäische Norm befasst sich nur mit Baumusterprüfungen.
Geräte, die mit Gasen der dritten Gasfamilie mit höheren Drücken als in 4.2 beschrieben betrieben werden,
liegen außerhalb der Anwendung dieser Europäischen Norm.
Bei der Erstellung dieses Textes wurde ersichtlich, dass das Konzept des thermischen Wirkungsgrades für
Geräte wie Grillgeräte nicht geeignet ist.
Die Gründe hierfür sind:
- beim Garvorgang findet infolge des auf die feuerfesten Materialien tropfenden Fleischsaftes ein
zusätzlicher Wärmeübergang statt;
- es besteht keine Beziehung zwischen dem Gargut und der Nutzfläche;
- das Grillgerät ist ein Gerät zur Verwendung im Freien, bei dem die Windeinwirkung hinsichtlich des
Wirkungsgrades eine große Rolle spielt.
Aus diesem Grund gibt es für diese Art von Geräten keine besonderen Anforderungen bezüglich des
thermischen Wirkungsgrades.
Diese Europäische Norm legt nicht alle anzuwendenden Anforderungen für integrierte Bauteile anderer Art
fest (z. B. Brenner nach EN 484).

Spécifications pour les appareils fonctionnant exclusivement aux gaz de pétrole liquéfiés - Barbecues utilisés en plein air y compris grilloirs par contact

La présente norme a pour but de définir les caractéristiques de construction et de fonctionnement ainsi que les spécifications de sécurité et les méthodes d'essai afférentes, et de marquage, des barbecues fonctionnant aux gaz de pétrole liquéfiés désignés dans l'ensemble du texte par "appareils".
La présente norme s'applique aux barbecues tels qu'ils sont définis en 3.6 et aux grilloirs par contacts tels qu'ils sont définis en 3.8, utilisés en plein air et fonctionnant avec les gaz donnés en 4.1 suivant les catégories précisées en 4.2. Ils sont équipés d'au moins un accessoire de cuisson.
La présente norme s'applique à tous ces appareils ou éléments que ces derniers soient indépendants ou incorporés dans un ensemble.
La présente norme s'applique également aux appareils destinés à être intégrés.
La présente norme couvre uniquement les essais de type.
Les appareils alimentés avec les gaz de la troisième famille à des pressions supérieures à celles définies en 4.2 sont exclus du domaine d'application de cette Norme européenne.
Lors de l'élaboration de ce texte, il est apparu que la notion de rendement thermique pour des appareils tels que les barbecues n'est pas appropriée.
En effet :
-   dans l'acte de cuisson, il existe un transfert thermique supplémentaire dû aux exsudats qui tombent sur les matériaux réfractaires ;
-   il n'y a pas de relation entre la pièce à cuire et la surface utile ;
-   le barbecue est un appareil de plein air dans lequel l'action du vent est prépondérante en termes de rendement.
En conséquence, ce type d'appareils ne donne lieu à aucune prescription spécifique concernant le rendement thermique.
Cette Norme européenne ne spécifie pas toutes les exigences applicables aux équipements incorporés d’autre nature (par exemple brûleurs couverts par l’EN 484).

Specifikacija za plinske aparate na utekočinjeni naftni plin - Žari za uporabo na prostem, vključno z žari s ploščo

Ta evropski standard določa značilnosti izvedbe in delovanja, varnostne specifikacije, ustrezne preskusne metode in označevanje žarov na utekočinjen naftni plin, ki se v besedilu imenujejo »aparati«. Ta evropski standard zajema žare iz točke 3.6, žare s ploščo iz točke 3.8 za uporabo na prostem, ki delujejo na pline iz točke 4.1 v skladu s kategorijami iz točke 4.2. Nameščeno imajo najmanj eno kuhalno napravo. Ta evropski standard se uporablja za te aparate in njihove funkcionalne dele, ne glede na to, ali so ti deli samostojni ali vgrajeni v sestav. Ta evropski standard se uporablja tudi za aparate, ki so namenjeni vgradnji. Ta evropski standard se uporablja le za tipsko preskušanje. Aparati na plin tretje družine pri tlaku, ki presega tlak iz točke 4.2, so zunaj področja uporabe tega evropskega standarda. Med pripravljanjem tega besedila je bilo očitno, da koncept toplotne učinkovitosti pri aparatih, kot so žari, ni primeren. Razlogi za to so: med pečenjem pride do dodatnega prenosa toplote, ker mesni sokovi padajo na ognjevzdržen material; med hrano, ki se peče, in koristno površino ni povezave; žar je zunanji aparat, pri katerem ima delovanje vetra pomemben vpliv na učinkovitost. Posledično ni posebnih zahtev v zvezi s toplotno učinkovitostjo za to vrsto aparata. V tem evropskem standardu niso navedene vse veljavne zahteve za sestavno opremo druge narave (na primer gorilniki, zajeti v standardu EN 484).

Foreword

This document (EN 498:2012) has been prepared by Technical Committee CEN/TC 181 “Dedicated liquefied

petroleum gas appliances”, the secretariat of which is held by AFNOR.

This European Standard shall be given the status of a national standard, either by publication of an identical

text or by endorsement, at the latest by July 2012, and conflicting national standards shall be withdrawn at

the latest by July 2013.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 498:1997.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative Annex ZA which is an integral part of this document.

The main changes compared to the former version are the following:

 approved quick self closing connection used for auxiliary burners are not subjected to the obligation of

being manufactory mounted;

 clearer specifications for lighting and cross lighting when more than one burner are in a same enclosure,

use of flash tube;

 introduction of a logo or warning forbidding cylinders in places of the appliance not designed for cylinder

storage;
 rewording of the test for checking over heating of gas cylinder compartment;

 addition of a warning about the updating of information relating to national situations;

 addition of an annex listing the mandatory sentences to be written on appliances, packaging and in

instructions in the various CEN members countries languages.

Items relating to quality assurance systems, production testing and particularly certificates of conformity of

auxiliary equipment are not covered by this European Standard.

Particular attention should be paid to the quality of non metallic materials used in the construction of these

appliances. A European Standard specifying requirements for "Rubber materials for seals and diaphragms

for gas appliances and equipment" has been prepared by CEN TC 108 (EN 549). A European Standard for

"Flexible hose, tubing and assembles for use with butane or propane in the vapour phase" is being prepared.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following

countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus,

Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,

Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,

1 Scope

This European Standard specifies the constructional and performance characteristics, safety specifications,

relevant test methods and marking of barbecues burning liquefied petroleum gas, referred to in the body of

the text as "appliances".

This European Standard covers barbecues as defined in 3.6 and contact grills as defined in 3.8, used

outdoors and operating with the gases indicated in 4.1 according to the categories indicated in 4.2. They are

fitted with at least one cooking device.

This European Standard applies to these appliances and their functional sections whether or not the latter

are independent or incorporated into an assembly.
This European Standard also applies to appliances designed to be built-in.
This European Standard only applies to type testing.

Appliances supplied with third family gas at pressures greater those defined in 4.2 are outside the field of

application of this European Standard.

During the consideration of this text, it was apparent that the concept of thermal efficiency with regard to

appliances such as barbecues was not appropriate.
This is because:

 during cooking, there is an additional transfer of heat due to the meat juices falling onto the refractories;

 there is no relation between the item to be cooked and the useful area;

 the barbecue is an outdoor appliance in which the action of the wind is important in relation to efficiency.

In consequence there is no specific requirement covering thermal efficiency for this type of appliance.

This European Standard does not state all applicable requirements for integral equipments of other nature

(for example burners covered by EN 484).
