We have received all the instruments, and will test them, for the moment we have very good feelings. Thank you.

—— Mr.Brett Cirulis

I really would like to work with YUYANG, their professional service on the laboratory solution and reliable products help me win much market!

—— Mr. Allan Ken

Nice cooperation! We appreciated for your company's kind support on our projects. Very good service.

—— Mr. Jaleshwar Prasad

I was set up your machine one week ago. İt’s good working. Thank you for all.

—— Ms.Erdem Traina

Quality is your factory culture, Quickly response is your core! Keep it and let YUYANG brand testing machine around the world.

—— Mr. Komarov Mihail

There are seldom suppliers willing to do small spare parts for us, while YUYANG spends time with us, only for three burners, we appreciate them.

BS476 Part 6 Fire Propagation Index Test Apparatus for Walls and Ceilings



  1. BS 476-6 is a test method of measuring the flame propagation properties of materials, primarily for fire protection performance evaluation of the walls and ceilings, measurement results are expressed as an index of flame propagation.
  2. During the test, the specimen is exposed to the tubular torch, heat release of the lamp is 530J / S. 2 minutes and 45 secondslater, the two electric heater was adjusted to 1800 watts in total, 5 minutes after starting the test, reduced the power to 1500 watts, keep the power not changed until finishing the experiment, the total test time is 20 minutes.
  3. To assess the flame propagation index of the material to be tested in BS476-6 apparatus, thermocouple continuous recording chimney temperature and room temperature difference, and compared the results with the calibration curve, calibration curve based on the provisions of the density of asbestos - cement slab in the same measured way.
  4. Comparing the temperature difference value of two curves which measured at the same time. In the first three minutes of the test, take the temperature difference value every 30 seconds, in the following 4-10 minutes, take the temperature difference value every one minute. In the last 11-20 minutes, take the temperature difference value every two minutes. Theflame spread index of these three periods are calculated according to formula.
  5. I is the value of sum of the three periods flame spread index. The higher of I value, the lower the material flame retardant, 0 grade material I≤12.


Data Acquisition system:

  • BS476-6 appratus is designed with prompted software interface

  • This test equipment can record data and display cowl temperature against time

  • Fire propagation index tester can also record data and display ambient temperature against time

  • Display of power value in kW

  • Calibration routine

  • Calculation of output rise and calibration value



  • Stainless steel support frame andCalcium silicate board combustion chamber.

  • Three kinds of sample holders for different thickness of the specimens.

  • Low reflective black finished mild steel Chimney and Cowl assembly complete with thermocouple mounting points.

  • Compliant stainless steel gas burner.

  • Two K type mineral insulated thermocouples complete with ceramic insulators.

  • Two pencil type heaters with 1000w installed in combustion chamber.

  • Control gas instrumentation including electronic gas on/off valve, flow regulating valve, flow meter and manometer.

  • Intelligent single phase power controller with feedback loop for accurate control of electric heating elements

  • DAQ record automatically the mV output from the thermocouples of the flue gases throughout the duration of the test.

  • According to the test time, BS476-6 test apparatus can automatically adjust the output power.
