This European Standard specifies the terminology, the general requirements for the construction and operation of forced draught gas burners and also the provision of control and safety devices, and the test procedure for these burners.
This European Standard is applicable to:
-   automatic gas burners with a combustion air fan (hereinafter called "burners") and gas line components, intended for use in appliances of different types, and that are operated with gaseous fuels;
-   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, which, for the latter, the requirements of EN 267 also apply.
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, see Annex J.
This European Standard specifies the requirements to ensure the safety during commissioning, start-up, operation, shut-down and maintenance.
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.

according to clause 1 and addition:
For piping this amendment applies only for pressurised parts and accessories with a product of the maximum allowable pressure PS and the diameter DN between 100 and 350 mm of less than 3 500 bar mm (category II) or with a product of PS and DN between 25 and 100 mm of less than 1 000 bar mm (category I), as defined by EU directive 97/23/EC.
Additional electrical functional requirements are given for monitoring devices.
The risk philosophy adopted in this standard is based on the analysis of hazards on account of pressure. The standard applies to the principals to eliminate or reduce hazards and where they can not be eliminated appropriate protection measures shall apply.
Any residual hazards are identified and communicated to the user where appropriate.
Depending on the installation situation additional requirements may apply to cover the risks arising from traffic, wind, earthquake loading and external fire.

according to clause 1 and addition:
Burners according to this standard are machines or components covered by the scope of EU directive 98/37/EC.
The risk philosophy adopted in this standard is based on the analysis of hazards on account of the application of burners as machinery according to EU directive 98/37/EC.
This standard together with Annex L deals with all significant hazards, hazardous situations and events relevant to burners, when they are used as intended and under the conditions foreseen by the manufacturer.
Any residual hazards are identified and communicated to the user where appropriate.
Depending on the installation situation additional requirements may apply to cover the risks arising from traffic, wind, earthquake loading and external fire.
This standard specifies the requirements to be met by the manufacturer to ensure the safety of persons and property during commissioning, start-up, operation, shut-down and maintenance, as well as in the event of foreseeable faults or malfunctions.
