Ventilation for buildings. Air terminal devices. Aerodynamic testing of damper and valves Ingestion-build-78747 Postal IT systems1 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
