Ventilation for buildings. Air terminal devices. Aerodynamic testing of damper and valves1 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

The bending test methods include outer bending test and inner bending test

the description of performance and test methods may need to be suitably adapted

The concepts and mechanisms described in this International Standard can be integrated in any existing RFID protocol approved by ISO/IEC for the given frequency range of 860 MHz to 960 MHz (unless explicitly prohibited by such protocol) regardless of the actual command set
