Relevance & Accuracy of Louvre Test Results
BSRIA Testing to BS EN 13030:2001 - Ventilation for Buildings - Terminals - Performance Testing of Louvres subjected to Simulated Rain
BSRIA being one of the only two laboratories in the world that is fully accredited and independent, ensures that the most stringent and credible test results are derived in accordance to the latest test standards.

BS EN13030 versus other testing facilities
A 1m x 1m louvre test sample and a 1.2m x 1.2m louvre test sample when subjected to a 2m3/s air volume have different air flow face velocities; 2m/s and 1.39m/s respectively. A difference of 30%!
BSRIA test - 1m x 1m Louvre
Other testing facilities - 1.2m x 1.2m Louvre
In summary, the BS EN13030 ensures more stringent testing conditions.
In order to ensure the consistent rain defence effectiveness as per the test result, it is only appropriate to incorporate drainages at every 1m length interval as per the test sample.
