Injectaclad BS8414-1 Testing
External wall systems are assessed for combustibility and ignitibility by reaction to fire performance tests that measure the contribution to fire growth, not the ability of a system to resist the passage of fire against time in terms of insulation and integrity.
British and European fire tests will coexist. The British Standards were due to be withdrawn, however, as the UK are no longer members of the EU the British Standards will remain in place.
Injectaclad has been tested and approved to BS8414 (Part 1). This test methodologies allow full scale testing of external wall insulation systems on a solid substrate (Part 1)
The test procedure sets up an identical system to the actual external wall insulation system on the building and is installed on a main test wall 8 m in height, 2.6 m wide with a 1.5 m wide return wing.
A 2m x 2m combustion chamber is located in the base of the main wall and a wooden crib ignited in the chamber to simulate fire break out from a window or doorway and its propagation over the façade.
Thermocouples installed through and within the external wall insulation system at various heights on the walls constantly monitor temperature to determine external and internal fire spread over the 30-minute fire duration which is followed by a 30-minute post fire observation period.
