Flame Spread Tester In Accordance With The ISO5658-2 Standard, And Simultaneously Meets The Relevant Requirements Of IMO FTP Code Resolution A.653 (16) And ASTM E 1317

The flame spread tester ISO5658-2 is developed and produced in accordance with the ISO5658-2 standard, and simultaneously meets the relevant requirements of IMO FTP Code Resolution A.653 (16) and ASTM E 1317. The Shenzhen Demaisheng Flame Spread Tester ISO 5658-2 is used to measure the lateral flame spread performance of building products. The flame spread performance/the speed of flame spread can evaluate the fire resistance and flame retardancy of materials.

This device radiates heat through a gas radiant plate and uses an imported heat flow meter to calibrate the radiant heat, then ignites the sample through a mixed gas burner to test the combustion condition of the material under a certain radiant heat. Expose the sample to an area with clearly defined radiation flux, and measure the ignition time, flame spread degree and final extinction time. The test samples are placed in a vertical position, close to the radiation plate, and exposed to the area clearly marked with radiation flux. The ignition flame approaches the test sample but does not come into contact with it. The heated end of the sample is ignited by the evaporated gas on its surface.
After ignition, record the development of the flame precursor and the time it takes for the flame precursor to burn horizontally on the sample surface to reach each calibrated distance. Furthermore, the relevant parameters of the material to be tested include ignition heat, sustained combustion heat, critical flow rate, average heat of sustained combustion, total heat release, etc.

Features
The box body is made of stainless steel, which is beautiful and corrosion-resistant. Easy to clean; The main frame is composed of two independent parts: the burner frame and the sample support frame. The two parts are connected by bolts, and there are bolts that can be flexibly mechanically adjusted.
Ignition source: Radiant plate and propane blowtorch imported from the United States. Precisely control the height of the flame
Burner, (200±10) mm long double-hole ceramic tube
The cylinder-type ignition burner supports the automatic flame impact test in accordance with IMO standards
The double-layer grid and the magnified perspective mirror facilitate users to observe the spread of the flame
Radiation plate temperature controller: Prevent the flame from turning to the rear side of the heat dissipation plate, check the internal temperature of the heat dissipation plate, and detect the flame
The flow controller can easily test the content of methane when testing the critical heat flow of gas
Gas supply: Equipped with pressure reducing valves, zero-pressure valves, tempering valves, solenoid valves and mixers, the mixed air and gas are delivered to the radiant panels.
It provides a multi-hole calibration plate and a sliding heat flow meter moving track to detect whether the thermal radiation flux meets the standard requirements
It is equipped with an adjustable-angle observation mirror (750mm×120mm). During the test, the flame spread rate can be observed through the glass mirror and the sample rake. It can also be automatically recorded by the foot switch.
Sample chimney, 1, equipped with gas and chimney metal compensating thermocouple.
All the safety explosion-proof, check valves and gas cut-off solenoid valves in the radiation plate combustion control system can prevent gas backflow
The camera can observe and save the status of the testing process in a certain program
Measure the heat flow state of the radiant panel within a 50mm interval
The data acquisition system can store images of flame spread length and combustion characteristics
The 19 "analysis rack can measure the flame spread rate, critical flow rate and heat release rate
The radiant plate burner system is fully automated, equipped with spark ignition and safety lock. All control systems are explosion-proof
The IMO program makes all calibrations, tests, and test result printing (IMO, ISO) easier
Mitsubishi PLC control system.
