Performance of Louvres Subjected to Simulated Rain
Eurofins Expert Servise Ltd has a test apparatus for measuring the water rejection performance and the pressure loss of louvres subjected to simulated rain according to EN 13030:2001 “Ventilation for buildings - Terminals – Performance testing of louvres subjected to simulated rain”. The measurements in controlled laboratory conditions produce useful knowledge of the performance of louvres.
Standard EN 13030:2001 can also be applied to different kind of ventilation products. Ask more from our experts.
The test apparatus for measuring the water rejection performance of louvres subjected to simulated rain is designed to 1000 mm x 1000 mm louvres. It is also possible to apply test rig to different sizes and products. Air is conducted at 13 m/s from the wind simulation equipment (1) to the weather section (3) in order to simulate wind effects.
