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 transmittance: (see Annex B).
The acoustic testing of dampers and valves is not included in this European Standard.
The tests specified above apply to the following:
f) measurement of leakage past a closed damper or valve;
g) measurement of casing leakage;
h) determination of flow rate and pressure requirements;
i) measurement of torque characteristics (see Annex A);
j) measurement of thermal transfer characteristics to determine insulation properties (see Annex B).
