ISO 12468-1 Roof External Fire Exposure Testing Machine for Building Materials
The Roof External Fire Exposure Tester is a precision testing device specifically designed to evaluate the fire resistance of roofing materials and systems under external fire conditions. It strictly complies with leading international standards including ISO 12468-1:2013, CEN/TS 1187:2012, ASTM E108, and EN 13501-5.
This equipment accurately tests flame propagation, penetration, and combustion behavior of roofing materials under real fire conditions by simulating various external fire source scenarios, including flame propagation, flame spread, wind-assisted flame, and radiant heat.
