5 Performance testing of aerodynamic characteristics
5.1 Aero and hygro-dynamic performance
5.1.1 Principle
This test consists of measuring several volume flow rates induced through a device controlled by
humidity conditions, under an applied static pressure difference, to define the flow rate/humidity
characteristic curve.
5.1.2 Test installation, conditions and uncertainty of measurement
5.1.2.1 Test installation and conditions
The test facility shall include two rooms controlled both in humidity and temperature, the first one
representing outside conditions, the other one indoor conditions as described in Figure 3.
The test installation and the indoor room shall comply with 4.1.2.1 of EN 13141-1:2004.
The test facilities shall have a range from 0 Pa to + 100 Pa.
Special care to limit air velocities around the inlet in the test box should be taken: air velocities shall
-1
be measured at locations specified in Figure 2. The measures shall not exceed 0,10 m.s at these
points without air flow through the air inlet.

5 static pressure probes or piezometric ring
Figure 3 — Test installation
To avoid difficulties in the control of the room (A), the volume shall be big enough, especially for non-
isothermal conditions measurements for which the “outside air” room (B) may strongly interfere with
the climate in room (A).
The size of room (B) is normally of lesser importance as the climate conditions are not to be so
accurate as in room (A), nevertheless it shall not affect the low velocity on the air intake of the device
under test.
The wall between room (A) and room (B) shall be insulated to avoid low temperature radiation on the
device under test.
Test plates shall conform to EN 13141-1.
The air permeability of the test equipment between the air inlet and the airflow/pressure measurement
devices shall be measured with the test specimen sealed, over the same range of pressure
differences used during the performance testing of the specimen.
The air permeability of the test equipment shall be reported and shall generate a leakage lower than
-1
1 l. s at 100 Pa.

SIST EN 13141-9:2008
EN 13141-9:2008 (E)
For low airflow measurements, it may be necessary to introduce some additional by-pass flow. This
by-pass flow shall be measured alone and reported.
In all cases, the leakage airflow shall be measured and used in the test report for correction of values
and for uncertainty calculations.
5.1.2.2 Uncertainty of measurement
The pressure shall be measured with an uncertainty lower than:
0,2 + 0,03 × (measured value) (Pa)
The volume flow rate shall be measured with an uncertainty lower than:
-1
0,3 + 0,03 × (measured value) (l⋅s )
The temperature shall be measured with an uncertainty lower than ± 0,5 K.
The relative humidity shall be measured with an uncertainty lower than 2 % RH.
5.1.3 Test procedure
5.1.3.1 Choice of tests to be performed
To check the humidity control of the devices, the measurements shall be taken in isothermal
conditions (see 5.1.3.2) for at least one pressure difference (chosen by the manufacturer) in the
following pressure difference ranges (bands) given in Table 2: 1, 2, 4, 10 or 20 Pa. Measurements in
non-isothermal conditions (see 5.1.3.3) at the same chosen pressure shall be made if the sensor can
be influenced by outdoor air temperature.

For manually openable or closable devices, in addition, the tests of EN 13141-1 shall be done in open
and closed conditions.
For pressure difference controlled devices, in addition self regulation shall be verified (see 5.1.3.4) in
isothermal conditions.

For non pressure difference controlled devices, an additional test shall be done according to
EN 13141-1 to determine the flow exponent at the middle point of the response curve to measure the
impact of pressure on the aperture. The test procedure of 5.1.3.4 of this document and 4.1.3 of
EN 13141-1:2004 shall be used for fixed devices.
The report shall give values of the flow exponent for the corresponding pressure difference as shown
in Table 3. If the regression law coefficient is lower than or equal to 0.95, a unique value of the flow
exponent shall be provided.
