Ventilation for buildings. Air terminal devices. Aerodynamic testing of damper and valves Ingestion-build-78747 the description of performance and1 Scope This European Standard specifies methods for the testing and rating of dampers and valves used in air distribution systems with pressure differences up to 2 000 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
