This standard specifies the terminology, the general requirements for the construction and operation of automatic forced draught gas burners and also the provision of control and safety devices, and the test procedure for these burners. This standard is applicable to - automatic gas burners with a combustion air fan and gas line components, intended for use in appliances of different types, and that are operated with gaseous; - total pre mixed burners and nozzle mixed burners. - single burners with a single combustion chamber; - single fuel and dual fuel burners when operating only on gas; - the gas function of dual-fuel burners designed to operate simultaneously on gaseous and liquid fuels. This standard deals with all significant machine hazards, hazardous situations and events relevant to burners, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. It specifies the requirements to be met by the manufacturer to ensure the safety during commissioning, start-up, operation, shut-down and maintenance. This standard does not deal with hazards due to specific applications. This standard does not apply to burners specifically designed for use in industrial processes carried out on industrial premises. This standard is not applicable to automatic forced draught gas burners which are manufactured before the date of its publication as EN. This standard deals also with the additional requirements for the burners in the scope with pressurised parts and /or firing pressurised bodies. This standard considers the requirement from the following directives: - Gas Appliance Directive 90/396/EEC - Machinery Directive 98/37/EC and 2006/42/EC - Pressure Equipment Directive 97/23/EC and gives an overview concerning this consideration in the informative annexes ZB, ZC, ZD and ZE.
