This standard specifies the constructional and performance characteristics, safety specifications and rational use of energy, relevant test methods and marking of boiling burners burning liquefied petroleum gas and designed to heat up vessels containing liquids or food, or a heating plate. They are referred to in the body of the text as "appliances".  This standard covers appliances, generally floor standing, fitted with one or several burners with a total heat input not exceeding 14 kW, designed to be used outdoors and operating with the gases indicated in 4.1 according to the categories indicated in 4.2.  Appliances supplied with third family gas at pressures greater those defined in 4.2 are outside the field of application of this standard.  Appliances covered by this standard are not connected to a flue for the products of combustion and are not connected to the mains electrical supply.  Appliances with a nominal heat input below 1,16 kW and appliances which are not designed to receive the test vessel described in 7.1.4 in any of their configurations are not subject to any requirement concerning the rational use of energy.   This standard applies only to type testing.
