EN 12101-3 came into effect in April 2005 and is primarily targeted at the specification requirements for extraction fans used in systems for the control of smoke and heat. There are various stipulated methods of testing these kinds of smoke ventilation systems and the motors requires to power them to ensure they are fit for their primary purpose of keeping escape and access routes smoke and heat free in the event of a fire. The standard also looks to ensure that the spread of the fire is slowed or halted all together and that vital equipment is protected. Ceiling temperatures must also be prevented from increasing too much to maintain the structural integrity of the building is not compromised by the increased thermal burden. Fans are divided into classes which helps in determining how they should be performing in emergency situations. These classes can be seen in the table below:

Class division standard EN 12101-3
F200 resistant to 200˚C for 120 min
F300 resistant to 300˚C for 60 min
F400 resistant to 400˚C for 120 min
F600 resistant to 600˚C for 60 min
F842 resistant to 842˚C for 30 min

In the case of the motors that power the systems, EN 12101-3 requires that they are able to operate efficientlty in normal ambient temperatures and in emergency situations (higher temperatures). There are also requirements outlined for the construction of the motors and the test settings for both the motors and the fans.

It is incredibly important that any smoke vents you purchase are fully compliant with these regulations, so be sure to make the right choices with us here at Smoke Vents.
