24、icated 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 withdr
25、awn 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 ha
26、s 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 compar
27、ed 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;
28、 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 a
29、nnex 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 E
30、uropean 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 (E
31、N 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
32、: 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 Un
33、ited Kingdom. BS EN 498:2012EN 498:2012 (E) 6 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
34、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 an
35、d 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
36、 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 trans
37、fer 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 cover
38、ing 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). 2 Normative references The following referenced documents are indispensable for the application of thi
