Fire Testing
Quelfire products are tested as a system to BS EN 1366-3 (service penetration sealing solutions) or BS EN 1366-4 standards (linear gap sealing solutions). We conduct regular tests to extend our portfolio to new applications based on feedback from our customers and industry trends.
BS EN fire testing is designed to replicate a flashover fire. With actual furnace temperatures being capable of exceeding 500°C within the first minute, this method is extremely onerous and aggressive. Therefore, all firestopping products must be capable of rapid expansion to ensure quick closure of the service penetration.
Both BS EN 1366-3 and BS EN 1366-4 employ a cellulosic test method to evaluate both fire integrity and insulation properties.
BS EN 1366-3 Test Standard
Service penetration seals are fire tested to the BS EN 1366-3 test standard and can then generally be classified to EN 13501-2. Such products are referred to as penetration seal systems that fall under ETAG 026 and are commonly intumescent based. This means they expand when exposed to fire to seal off the pipe or duct, preventing fire spread.
BS EN 1366-4 Standard
Linear gap seals are tested to BS EN 1366-4 which assesses the capacity of a product to effectively seal a gap between two surfaces in a specific arrangement. BS EN 1366-4 can also cover timber door frames as set out in the National Annex NA: Standard Conditions for Linear Joint Seal Materials […].
