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.
