CEN/TC 156 Ventilation for buildings

European Norm

91.140.30   Ventilation and air-conditioning systems


This European Standard specifies methods for the testing and rating of dampers and valves used in air distribution systems with pressure differences up to 2000 Pa. The tests incorporated in this European Standard are: a) leakage past a closed damper or valve (for classification see annex C); b) casing leakage (for classification see annex C); c) flow rate/pressure requirement characteristics; d) torque: (see annex A); e) thermal transmittance: (see annex B).
