BS EN 12101-2:2003 is a European Standard which specifies requirements and gives test methods for natural smoke and heat exhaust ventilators which are intended to be installed as a component of a natural smoke and heat exhaust system.
To comply with Construction Products Regulations, AOV systems must be CE marked against this standard.
In order to be efficient, AOV systems must undergo a series of rigorous tests which adhere to BS EN 12101-2:2003.
These tests typically include cycle testing over many thousands of operations and also testing in a high and low temperature range with no more than a 10% reduction in opening area. The unit will be required to function under snow and wind loads, whilst opening to fire position using both mains and battery power in under 60 seconds.
Any manufacturer that has carried out these tests must provide a Certificate of Conformity supplied by a UKAS accredited body. This details the loadings and temperature ranges the AOV has been subjected to during testing and should be accompanied by a Declaration of Performance.
