Flammability Testing Equipment Large Scale Vertical Fire Resistance Test Furnace
Application:
Evaluate the fire resistance of vertical construction products
Standards:
BS 476 (20-23) – BS EN 1363 (1-2) – BS EN 1364 (1) – BS EN 1365 (1) BS EN 1366 (1-3) - BS EN 1634-1 – ASTM E 119 – ASTM E 814 - UL10 (B-C) - UL 263 – UL 1709 - UL10 (B-C) – UL 1479 – UL 2079 -- ISO 834 (1, 4, 8) - ISO 3008 – ISO 3009
Descriptions:
The fire resistance properties of a material provide invaluable information to assess the behaviour of a specimen and its assemblies.
The Vertical Fire Resistance Test Furnace provides a method of quantifying the ability of products and materials, in a vertical orientation, to withstand exposure to high temperatures. The furnace can be used for evaluating the fire resistance of products such as walls, doors, dampers, joints, and penetration seals. This is done by evaluating a number of functions including; the load-bearing capacity, the fire containment and the thermal transmittance of the assemblies being tested.
Specifications:
The system features:
LP Gas Industrial Refractory Luminous Soft Flame Burners
In the upright furnace position, 6 burners are installed on each of
the left side and right side of the furnace wall. Each burner is
designed to use liquefied petroleum gas and all of the necessary
flame safety systems, intermittent pilot systems, and temperature
sensors are incorporated.
Lifting Frame and Restraint Frames for Test Specimens
Two units of Frames are supplied for mounting vertical specimens.
The refractory lining is made of pre-cast refractory blocks,
anchored to the steel frame. These frames are non load bearing
frames. A separate customized lifting frame with two side hooks is
provided to lift the specimen restraint frame to the furnace. This
allows easy placement of the vertical and horizontal restraint
frames into the furnace.
Refractory Lined Connecting Duct And Exhaust Stack
The Chimney/Stack is constructed of 9mm thick mild steel and is
refractory lined for the first 6 metres. The Stack extends to a
minimum of 3 metres above the factory roof level or in accordance
to the local Code requirements.
Combustion Air Blower to Furnace Burners
The combustion air system is pre-piped and tested before dispatch.
Temperature Sensors and Manometer
The system is supplied with 9 Type K thermocouples and plate
thermometers, a pressure manometer and an ambient thermocouple
assembly.
PLC System
The PLC System is comprised of a Siemens PLC CPU and Siemens
compatible remote I/O. The fire resistance data management software
is custom written to accept and save data collected during the
tests and is configured to meet the heating requirements of BS 476
Parts 20 - 22, EN 1363 and IMO Hydrocarbon test curve. Other
standard Time-Temperature curves can also be pre-programmed into
the system. The PLC controller incorporates a built-in operator
interface, contains the required recording and programming
capabilities and includes all necessary motor starters for all
motors in the system. The system is programmed to provide real time
heating curves and display all furnace control information on the
computer screen.
