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

BS 1186-2 on specifications for workmanship is useful for:

PD IEC/TS 62056-8-20 provides you with a DLMS/COSEM communication profile that can be used in a smart metering system in which the Neighbourhood Networks (NN) are mesh networks

the test results can help you make the right selection of electrical insulating materials that suit your specific engineering needs
