This European Standard specifies methods for the testing and rating of dampers and valves used in
air distribution Systems with pressure differences up to 2000 Pa.
The tests incorporated in this European Standard are:
a) leakage past a closed darnper 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 include
The tests specified above apply to the following:
d in this standari
a) measurement of leakage past a closed darnper or valve;
b) measurement of casing leakage;
C) determination of flow rate and pressure requirements;
d) measurement of torque characteristics (see annex A);
e) measurement of thermal transfer characteristics to determine insulation properties (see
annex B).
NOTE: Certain aspects of the dynarnic performance of dampers or valves are dependent
upon the air distribution system to which they are connected and are, therefore, difficult to
measure in isolation. Such considerations have led to the omission of these aspects of the
dynarnic performance measurernents from this European Standard. Also, in common with
other air distribution components, the results from tests carried out in accordance with this
European Standard may not be directly applicable if the darnper or valve is situated in an area
of non-uniform flow.
