Introduction:

BS **6 part 6 specifies a method of test, the result being expressed as a fire propagation index, that provides a comparative measure of the contribution to the growth of fire made by an essentially flat material, composite or assembly. It is primarily intended for the assessment of the performance of internal wall and ceiling linings.


Feature:

1. Stainless steel support frame andCalcium silicate board combustion chamber.
2. Three kinds of sample holders for different thickness of the specimens.
3. Low reflective black finished mild steel Chimney and Cowl assembly complete with thermocouple mounting points.
4. Compliant stainless steel gas burner.
5. Two K type mineral insulated thermocouples complete with ceramic insulators.
6. Two pencil type heaters with ***0w installed in combustion chamber.
7. Control gas instrumentation including electronic gas on/off valve, flow regulating valve, flow meter and manometer
8. Intelligent single phase power controller with feedback loop for accurate control of electric heating elements
9. DAQ record automatically the mV output from the thermocouples of the flue gases throughout the duration of the test.
10. According to the test time, automatically adjust the output power.

1. Prompted software interface
2. Data recording and display of cowl temperature against time
3. Data recording and display of ambient temperature against time
4. Display of power value in kW
5. Calibration routine
6. Calculation of output rise and calibration value
