The performance of walls, columns, floors and other building elements when exposed to fire conditions is of extreme importance in ensuring safety to both the public and neighbouring structures. In order to acquire information on this performance, it is necessary to measure the fire-resistive properties of the materials and assemblies in question.
The FTT Fire Resistance Test Furnace for vertical and Horizontal Test Specimens is the apparatus needed to evaluate the fire resistance of a horizontal or vertical construction assembly, column, or support, and provides a method of quantifying the ability of products such as doors and dampers, and building materials 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.
The unique ability of the FTT Furnace to test both Horizontal and Vertical test specimens provides the most efficient way to maximise your test equipment budget.
Lifting and Restraint Frames for Test Specimens Two units of Frames are provided for mounting vertical specimens and another two units for horizontal 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 customised 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 on the furnace.
Furnace Tilting Mechanism A hydraulic tilting system comprising twin hydraulic cylinders is supplied. This device enables the user to position the furnace in an upright position in order to carry out vertical fire resistance tests or to lower the furnace to a horizontal plane, allowing horizontal tests to be carried out.
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. TheStack extends to a minimum of 3 metres above the factory roof level or in accordance with 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 9Type K thermocouples and plate thermometers, a pressure manometer and an ambient thermocouple assembly.
- The PLC System is comprised of 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 476Parts 20-22, EN 1363 and IMO Hydrocarbon test curve. Other standard Time-Temperature curves can also be 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 real-time furnace control information on the computer screen.
