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text or by endorsement, at the latest by July 2012, and conflicting national standards shall be withdrawn at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,
Spain, Sweden, Switzerland, Turkey and the United Kingdom.
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).

4 Classification
4.1 Classification of gases used
Gases used are classified in families and groups according to their Wobbe number.

The third family, grouping liquefied petroleum gases, covers Wobbe indexes between 72,9 MJ/m and

87,3 MJ/m (W ) which corresponds to group B/P. It is subdivided into two groups, group P which covers the
s
3 3
range of Wobbe indexes between 72,9 MJ/m and 76,8 MJ/m , and group B which covers the range of

3 3
Wobbe indexes between 81,8 MJ/m and 87,3 MJ/m .
4.2 Classification of appliances
Appliances are classified into categories according to the gases that they use. However, for each country,
only some of the categories mentioned below are applicable on account of local gas supply conditions (types
of gas and supply pressures). For these categories, no requirement different from those defined in this
European Standard shall be applied.
The gas supply conditions and types of connection applicable to each country are given in Annex A.
Appliances within the field of application of this standard belong to the following categories:
a) Category I :
3B/P(30)
Appliances capable of using third family gases (propane, butane or their mixtures), without adjustment at
nominal operating pressures from 28 mbar to 30 mbar;
b) Category I :
3B/P(37)
Appliances capable of using third family gases (propane, butane or their mixtures), without adjustment at
nominal operating pressures of 37 mbar;
c) Category I :
3B/P(50)
Appliances capable of using third family gases (propane, butane or their mixtures), without adjustment at
nominal operating pressures of 50 mbar;
d) Category I :
3+(28-30/37)
Appliances capable of burning third family gases (butane and propane), and operating without adjustment on
the appliance using a pressure couple; for butane, appliances in this category may be used without
adjustment at nominal operating pressures from 28 mbar to 30 mbar, for propane they are used at a nominal
operating pressure of 37 mbar;
e) Category I :
3P(37)
Appliances capable of using third family gases in group P (propane), without adjustment at a nominal
operating pressure of 37 mbar;
f) Category I :
3P(50)
Appliances capable of using third family gases in group P (propane), without adjustment at a nominal
operating pressure of 50 mbar.
