Descriptions:
The fire resistance of a material forming part of an assembly is an
invaluable tool in assessing the performance of construction
elements relied upon in regulations.
Specifications:
The Horizontal Fire Resistance Test Furnace is the apparatus needed
to evaluate the fire resistance of a horizontal construction
assembly, column, or support, and provides a method of quantifying
the ability of a material, in a horizontal orientation, to
withstand exposure to high temperatures. This is done by evaluating
a number of performance elements such as the load-bearing capacity,
the ability to provide fire containment and the thermal
transmittance of the materials and systems.
1. The capability to carry out both load-bearing and non-load
bearing tests on Horizontal Test Specimens and beams that are
mounted in customized restraint frames.
2. Superior and safe construction – furnace walls comprising a
lining of insulating fire bricks, refractory castables and mineral
fibre board on the cold face and refractory insulating bricks
anchored back to the wall with high temperature cast in-situ
blocks, on the hot face.
3. A removable roof lined with profiled bricks and anchored with
refractories cast in situ.
4. A furnace casing made of mild steel plates reinforced with steel
C-Channels, I-beams and steel sections to counter structural
distortion due to heat.
5. A specimen restraint frame secured by a minimum of 4 sets of
clamps.
6. 4 viewing ports made of heat resistant quartz glass to enable
the operator to view the complete test specimen during a fire test.
7. A sliding door made of light weight alumina is enclosed within
an insulated, air-cooled frame. This will shield off the furnace
heat when the viewing ports are not in use.
8. 20 sets of Refractory Nozzle Mix Burners (2 groups of 10). Each
burner is designed to use liquefied petroleum gas and has a flame
supervision unit to ensure that all combustion units operate on a
fail safe mode at all times. All necessary flame safety systems,
intermittent pilot systems, and temperature sensors are
incorporated.
9. A Furnace Combustion Control Panel is designed to operate on
both fully automatic and manual control modes. Automatic ignition
of the burners is through the use of one push button switch. This
fires up the burners based on a preset heating curve, such as that
described in BS 476 Parts 20-24, EN 1363 and the IMO Hydrocarbon
Curve. Manual burner control enables individual burners to be
ignited at will.
10. Test area dimensions: 3000mm (W) x 4000mm (H) x 1000mm (D)
