The environmental conditions existing during the tests such as temperature, barometric pressure shall be recorded. Air temperature θa shall be (20 ± 5) °C. During the test, temperature θa shall not vary more than ± 2 °C. The test shall be carried out by continuously increasing the pressure difference across the device. SIST EN 13141-2:2010

If the edge is not at 300 mm from the duct centreline, it shall be simulated by using a baffle of particle board, thickness 22 mm, minimum density 500 kg/m³ and minimum area 1 500 mm × 1 500 mm. 5.1.2.3 Air handling circuit The air circuit shall be designed as shown in Figure 3. An extraction fan shall be mounted in the air circuit and fitted with regulation devices and a silencer. The measured background noise of the test room when the air terminal device is removed should remain at least 6 dB lower than the noise measured with the device. SIST EN 13141-2:2010

The pressure drop through the air terminal device shall be measured as:

- ppp=∆ (5) where
patm is the atmospheric pressure in the room;
p1 is the static pressure measured in the duct at the position indicated in Figure 3. The static pressure shall be measured according to 4.1.
The air terminal device shall be mounted such that no air leakage can occur between the device and the air duct, to avoid the generation of narrow-band noise which can affect the results. The setting of any positioning parameter indicated on the adjustable terminal devices shal
