This European 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 (hereinafter called "burners") as described in 3.1.2 and
gas line components, intended for use in appliances of different types, and that are operated with gaseous
fuels;
total pre-mixed burners and nozzle mixed burners.
The standard is applicable to
single burners with a single combustion chamber;
single-fuel and dual-fuel burners when operating only on gas;
gas function of dual-fuel burners designed to operate simultaneously on gaseous and liquid fuels.
This European 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, see Annex J.
This European Standard specifies the requirements to be met by the manufacturer to ensure the safety during
commissioning, start-up, operation, shut-down and maintenance.
This European Standard does not deal with hazards due to specific applications.
This European Standard is not applicable to automatic forced draught gas burners which are manufactured before
the date of its publication as EN.
This European Standard does not apply to burners specifically designed for use in industrial processes carried
out on industrial premises.
This European Standard deals also with the additional requirements for the burners in the scope with pressurised
parts and /or firing pressurised bodies, see Annex K.
