5 Performance testing of aerodynamic and hygro-dynamic characteristics
5.1 Aero and hygro-dynamic performances
5.1.1 Principle
This test consists of measuring several volume flow rates induced through a device by humidity
conditions, under an applied static pressure difference, to define the flow rate/humidity characteristic
curve.
In the case of manually adjustable devices, a test according to EN 13141-2 shall be carried out at
specific opening conditions specified by the manufacturer.
Some exhaust air terminal devices are designed to work under both natural and mechanical
ventilation systems. In this case the manufacturer may have to specify two operational ranges, and
the device shall be tested for each of them.
5.1.2 Test installation, conditions and uncertainty of measurement
5.1.2.1 Test installation and conditions
The test facility shall include one room controlled both in humidity and temperature, representing
indoor conditions. The airflow test rig may be either in this room or outside but in this case, it shall be
verified that all test conditions are still valid, i.e leakages shall be included to achieve the overall
uncertainty of measurement that is required.
The test installation shall comply with those of EN 13141-2:2004, 4.1.2.1 for indoor rooms.
The test facilities shall have a range from – 300 Pa to 0 Pa.
Special care to limit air velocities around the inlet in the test box shall be taken: air velocities shall be
-1
measured at locations specified in Figure 2. The measures shall not exceed 0,10 m.s at these points
without airflow through the exhaust vent.

• Locations of the measurement points
d = 0,04 m
l = 0,20 m
Figure 2 — Locations of measurement points
To avoid difficulties in the control of the humidity and temperature controlled room, the volume should
be big enough.
The air permeability of the test equipment 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
0,1 l. s at 100 Pa.
NOTE For low airflow measurements, it can be necessary to introduce some intentional leakage.
In this case, 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
For fixed setting devices and manually adjustable, all the specified positions shall be tested with at
least the minimum and maximum open positions.
For a device or position humidity controlled, the measurements shall be taken (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.
For positions without humidity control, the same measurements as for fixed device (according to
EN 13141-2) in specific conditions shall be performed.
For pressure difference controlled devices, self regulation shall be verified (see 5.1.3.3).
For non pressure difference controlled devices, an additional and optional 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: use description in 5.1.3.3.
The environmental conditions existing during the tests, such as temperature and barometric pressure,
shall be recorded.
The volume flow rate q should be directly measured or alternatively calculated from the
v meas
measured value of mass flow rate q .

exponent shall be provided.
