Fire resistance test

Verification of fire resistance performance
Walls for use in fire resistant structure etc. is installed in a furnace for fire resistance tests (heating furnace), the burner in the furnace is used to raise the temperature inside the furnace according to the standard heating curve, then the surface temperature of walls not facing the furnace is observed, as well as observing for wall collapse, cracks and damage.

If the fire resistance is rated for 1 hour, heating is maintained for 1 hour. However, observation will continue for 3 hours after heating to confirm the safety of the wall.
