Semi Automatic 400 X 600 X 300mm Fire Propagation Index Tester

Tester for the fire propagation index with a calcium silicate board combustion chamber and a stainless steel support frame
Introducing the product
The test technique described in BS 476 part 6 provides a comparative measurement of the contribution to the spread of fire made by an essentially flat material, composite, or assembly. The test result is reported as a fire propagation index. Its main purpose is to evaluate the effectiveness of internal wall and ceiling linings.
Technical specifications
1. The stainless steel box support frame.
2.stainless steel sample holders, a combustion chamber made of calcium silicate board, a T-type burner, and an open flame combustion mode are all included.
3.. The power output is automatically controlled, and the output power is automatically changed in accordance with the test duration; 6. The thermocouple continually records the difference between the temperature and the room temperature in the chimney; 7.
4.Two thermocouples of the K type with mineral insulation and ceramic insulators.
5. The combustion chamber is equipped with two 1000-watt pencil-style heaters.
6. Instrumentation for controlling gas flow, such as a manometer, a flow metre, and an electronic gas on/off valve.
7. Smart single phase power controller for precise regulation of electric heating elements
8.During the course of the test, the DAQ will automatically record the mV output from the flue gas thermocouples.

9. Automatically change the output power in accordance with the test duration.
Application: It is mostly used to assess how well wall and ceiling linings resist fire.
Product Information
The BS 476-6 test method is a technique for figuring out a material's flame propagation characteristics. It is mostly used to assess how well wall and ceiling linings function in a fire. Flame propagation index is used to express the results. The test object was exposed to a tube torch during which time the lamp released 530 J/m of heat. The two electric heaters' combined wattage was set to 1800 watts at the end of the test's 2 minutes and 45 seconds. The power was decreased to 1500 watts after the first five minutes of the test and stayed there until the test was finished. The test took 20 minutes to complete.
