CEN/TC 58/WG 10 - Common requirements and test methods for standards for gas controls

This amendment to EN 13611:2000 is issued to align the standard with the essential requirements of the Pressure Equipment Directive (97/23/EC).

This European Prestandard specifies methods for the assessment of function blocks with regard to their fault behaviour and preventative measures. This European Prestandard covers control functions of electric and electronic controls that are used to prevent unsafe operation of gas burners and gas burning appliances.
NOTE 1: Function blocks which are not covered by dedicated control standards (see Annex A) are within the scope of this Prestandard.
NOTE 2: An electric or electronic device which contains a control function is based on the principle that it provides the same safety levels other technologies (e.g. mechanical solutions)

This European Standard deals with the safety, construction and performance requirements of safety, control or regulating devices and sub-assemblies or fittings (hereafter referred to as controls) for burners and gas-burning appliances using fuel gases of the 1st, 2nd or 3rd families and to their testing. This European Standard is to be used in conjunction with the specific control standard. When no specific control standard exists, the control can be tested according to this standard and further tests taking into account the intended use.
Controls to which this European Standard applies include the following: - Automatic shut-off valves; - Burner controls - Flame supervision devices; - Gas/air ratio controls; - Pressure Governors; - Manual taps; - Mechanical thermostats; - Multifunctional controls; - Pressure sensing devices; - Valve proving systems; - Zero governors The methods of test given in this standard are intended for product type testing. Tests intended for production testing are not specifically included.
