Overview
EN 13141-10:2008 - published by CEN - defines laboratory methods for performance testing of humidity-controlled extract air terminal devices used in residential ventilation. The standard covers devices controlled by indoor relative humidity in mechanical and natural ventilation systems (manually adjustable, fixed-setting, and self-adjusting pressure-differential devices). Tests characterize aerodynamic/hygro-dynamic behavior, acoustic performance and time response to changes in humidity.
Key topics and technical requirements
- Scope of testing: Measures the airflow vs indoor relative humidity characteristic curve under defined static pressure differences. Applies to devices intended for residential ventilation systems.
- Device types: Manually adjustable openings, fixed-setting humidity devices, and self-adjusting (pressure-difference) units.
- Test environment: Laboratory room with controlled temperature and humidity representing indoor conditions; test rig pressure range down to –300 Pa up to 0 Pa.
- Measurement points & cycles: Minimum of nine humidity/flow measurement points (minimum, maximum and intermediate points for increasing and decreasing cycles) to capture hysteresis and accurate response curves.
- Stability & timing: Relative humidity stability required within ±2% RH; stable period before measurement typically 45–60 minutes; maximum interval between consecutive measurements 90 minutes.
- Temperature control: Indoor air temperature around the sensor at 21 °C with variation limits ±1 K; temperatures measured at three locations near the device.
- Uncertainty and instrumentation: Specified maximum uncertainties for measurements - pressure, volume flow rate, temperature and relative humidity - to ensure traceable, repeatable results.
- Additional tests: Acoustic tests (device noise, insertion loss, sound insulation) and time-response tests to assess how quickly the device reacts to humidity changes.
- Data analysis: Determination of flow exponents and, where relevant, corrections for tests carried out at pressure differences different from the manufacturer’s nominal values.
Applications
- Product performance verification and R&D for manufacturers of humidity-controlled exhaust terminals.
- Independent laboratory testing for certification, product declarations and compliance with residential ventilation performance requirements.
- HVAC designers and specifiers selecting humidity-responsive terminal devices for dwellings to control indoor moisture and ventilation rates.
- Regulatory bodies and testing laboratories establishing baseline acoustic and dynamic behavior for devices used in homes.
Who uses this standard
- Ventilation product manufacturers and component developers
- Test laboratories and certification bodies
- HVAC designers, consultants and building services engineers
- Compliance and regulatory authorities in the EU

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.

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.
