EN 498:1997

This 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 standard covers barbecues as defined in 3.6, 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 standard applies to these appliances and their functional sections whether or not the latter are independent or incorporated into an assembly. This standard also applies to appliances designed to be built-in. This 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 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.
