Can the QWR Fire Collars be used in conjunction with plasterboard ceilings / timber frames? Penetration sealing
The QWR Fire Collars have also been tested generally in accordance with the BS EN 1366-3: 2009 fitted to plasterboard ceilings.
BS EN 1366-3:2009 Fire resistance tests are a method of evaluation for the ability of a penetration seal to maintain the fire resistance of a separating element at the position it has been penetrated by a service.
Penetration seals used for sealing gaps around chimneys, air ventilation systems, fire-rated ventilation ducts, fire-rated service ducts, shafts and smoke extraction ducts are all excluded from this standard except for mixed penetration seals.
The purpose of BS EN 1366-3 is to assess:
a) The effect of such penetrations on the integrity and insulation performance of the separating element concerned
b) The integrity and insulation performance of the penetration seal
c) The insulation performance of the penetrating service or services, and where necessary, the integrity failure of a service.
It’s not the intention of this test to provide quantitative information on the rate of smoke or hot gas leakages or on the transmission or generation of fumes. This test is also not intended to supply any information on the ability of the penetration seal to withstand stress caused by movements or displacements of the penetrating services. The risk of fire spreading downwards caused by burning material dripping through a pipe down to the floor below, can’t be assessed with this test.
