1500mm (W) ×1500mm (H) × 1500mm (D) INDICATIVE FURNACE

The Indicative Fire Resistance Test Furnaces provide a method of quantifying the ability of a
material or assembly to withstand exposure to high temperatures using only a fraction of the
material required by large full-scale furnaces.
This furnace is also ideal for evaluating the fire performance of dampers and penetration
seals for building services

System Description
• Four sides of the walls are lined with special high temperature insulating fire bricks on the
hot face and precast refractory castables at the edges exposed to the specimen restraint
frame as well as mineral boards on the cold face.
• A refractory lined Blank-Out Wall with lifting hooks is also supplied. This enables the user to
close one side of the furnace wall when either a vertical or a horizontal test specimen is
mounted for testing.
• A set of two self-locking clamps are used to secure the test specimen restraint frame to the
furnace. An air-cooled viewing port made of heat resistant quartz glass is installed in the rear
wall to enable the operator to see the behavior of the entire test specimen during a fire test.
• A sliding shutter door made of lightweight alumina fiberboard is supplied to shield off the
furnace heat when the viewing port is not in use.
• Approximate dimensions:
internal chamber measuring 1500mm (W) ×1500mm (H) × 1500mm (D).
