This European Standard specifies the general safety, design, construction, and performance requirements and testing for safety, control or regulating devices (hereafter referred to as controls) for burners and appliances burning one or more gaseous fuels or liquid fuels. This European Standard is applicable to controls with declared maximum inlet pressure up to and including 500 kPa of nominal connection sizes up to and including DN 250. This European standard specifies general product requirements for the following controls: - automatic shut-off valves; - automatic burner control systems; - flame supervision devices; - gas/air ratio controls; - pressure regulators; - manual taps; - mechanical thermostats; - multifunctional controls; - pressure sensing devices; - valve proving systems; - automatic vent valves. This European standard applies for control functions that are not covered by a specific control standard for burners and appliances burning one or more gaseous fuels or liquid fuels. This European Standard applies also for safety accessories and pressure accessories with a product of the maximum allowable pressure PS and the volume V of less than 600 000 kPa • dm3 (6 000 bar• litres) or with a product of PS and DN of less than 300 000 kPa (3 000 bar) . This European Standard applies for AC and DC supplied controls (for controls supplied by stand-alone battery system, battery systems for mobile applications or systems which are intended to be connected to DC supply networks controls see Annex I). This European Standard is applicable to reset functions used for reset from lockout, e.g. due to ignition failure or temperature cut-out in burners and appliances (see Annex M). This European Standard establishes methodologies for the determination of a Safety Integrity Level (SIL) and the determination of a Performance Level (PL) (see Annex J, Annex K and Annex L). This European Standard gives guidelines for environmental aspects (see Annex N). This European Standard does not apply to mechanical controls for use with liquid fuels. Protection against environmental impact in open air (i.e. capable of withstanding UV radiation, wind, rain, snow, dirt deposits, condensation, ice and hoar frost (see IEV 441-11-05:2005)), earth quake, external fire are not covered by this standard. This European Standard should be used in conjunction with the specific control standard (see Bibliography).

NOTE 1 Requirements for industrial valves are given in this International Standard and/or in other standards. Valves are to be used with components conforming to this International Standard provided that they conform additionally to the relevant requirements of this International Standard. This International Standard is applicable to either PB, PE, PE-RT, PE-X, or PP pipes, fittings, valves, and their joints and to joints with components of other plastics and non-plastic materials, depending on their suitability, intended to be used for the conveyance of liquid and gaseous fluids as well as solid matter in fluids for industrial applications such as the following: - chemical plants; - industrial sewerage engineering; - power engineering (cooling and general purpose water); - mining; - electroplating and pickling plants; - semiconductor industry; - agricultural production plants; - fire fighting; - water treatment; - geothermal. NOTE 2 Where relevant, national regulations (e.g. water treatment) are applicable. Other application areas are permitted if the requirements of this International Standard and/or applicable national requirements are fulfilled. National regulations in respect of fire behaviour and explosion risk are applicable. The components have to withstand the mechanical, thermal, and chemical demands to be expected and have to be resistant to the fluids to be conveyed.
