EN 161:2011/FprA1

Automatic shut-off valves for gas burners and gas appliances - Special requirements to determine performance level (PL)

The intention is to add a further Annex to EN 161 regarding a method for the determination of Performance Level (PL): This Annex is only applicable to valves or valve functions which are declared to comply with performance level requirements (PL) according to EN ISO 13849-1:2008, clauses 1, 2, 3, 4.1, 4.2, 4.5, 7, 8, 9, 10, 11, and annexes C.4, E, and F. This Annex specifies a set of additional requirements to EN 161 to determine the probability of dangerous failures per hour for continuous or high demand mode (PFHD) and the performance level (PL) for electromechanical valves or valve functions used in industrial and thermoprocessing applications (e. g. EN 746-2).
