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)
