Description:This part of EN 746 together with EN 746-1 specifies safety requirements for single and multiple burners that
are part of Industrial Thermoprocessing Equipment. (In this standard referred to as IThE).
This document deals with significant hazards, hazardous situations and events relevant to combustion and
fuel handling systems that are part of IThE as listed in Clause 4, when used as intended and under the
conditions foreseen by the manufacturer.
This European Standard covers:
? fuel pipework downstream of and including the manual isolating valve;
? burner(s), burner system and ignition device;
? safety related control system (protective system).
This European Standard applies to any oxidation with air or other gases containing free oxygen of gaseous,
liquid and solid fuels or any combustion of them to release thermal energy.
For thermal or catalytic post combustion and waste incineration, this European Standard applies only to
auxiliary burners designed to start-up and/or support the process.
The pressure hazard of the piping and components covered by this standard is within the limits of maximum
pressure/size relationship as described in normative Annex E.
This European Standard also gives the necessary requirements for the information for use.
This European Standard does not cover hazards from heating generated by electricity.
This European Standard does not deal with the hazards created by the release of flammable substances from
the products processed in the IThE.
This European Standard is not applicable to combustion and fuel handling systems
? of welding and soldering machines;
? up-stream of the IThE manual isolating valve.
This European Standard is not applicable to electricity cabling and power cabling upstream of the IThE control
Noise can be a significant hazard for combustion and fuel handling systems. It is not dealt with in this
This European Standard is not applicable to combustion and fuel handling systems as part of IThE which is
manufactured before the date of its publication as EN.
Overview: What is BS EN 746-2:2010?This part of BS EN 746 sets out the safety requirements for single and multiple burners that are part of industrial thermo-processing equipment. Dealing with significant hazards, hazardous situations and events relating to combustion and fuel handling systems, this standard helps organizations to put the right safety measures in place. BS EN 746 covers fuel pipework downstream of and including the manual isolating valve; burners and ignition devices; as well as safety related control systems. How does it work?BS EN 746 first looks at the list of hazards, before sharing equipment safety requirements, measures and verification means. It also sets out the verification of the safety requirements and measures – covering inspection procedures, commissioning, shut-down procedures and maintenance. Other topics include marking and documentation. Who should read it?Manufacturers of industrial thermo-processing equipmentInspectorsAnyone responsible for the design, installation and maintenance of industrial furnacesQuality assessorsWhy BSI?We are global, we’re independent and we’re a trusted service provider to 80,000 businesses.
