Imo Spread of Flame Apparatus

Description:
Lateral flame propagation properties for the determination of building products, flame propagation performance / flame spread rate of speed can evaluate the fire retardant properties of the material.

The device via a gas radiant plate to heat samples and with heat flow meter to calibration; Test samples were placed in a vertical position, near the radiation plate, exposed in a clear area calibrated radiation flux. Close to the pilot flame test sample, but not in contact with the test sample, the sample was heated end ignited gas on the surface of the evaporator.

After ignition, recording the development of the flame front, and record the flame front in a horizontal direction to reach the surface of the sample, combustion distance of each calibration elapsed time. Further testing materials include light heat, sustained combustion heat, critical flow, the average sustained burn calories, the total heat release and other relevant parameters.

Standards:
• ISO 5658-2: reaction to fire test – Flame spread Part 2: Vertical distribution of building products side flame spread level.
• IMO FTP Code Resolution A. 653 (16): bulkhead, ceiling and deck material flammability test procedures Advice
• ASTM E 1317: Marine Surface Finishes Standard Test Method for Flammability
• ASTM E1321： Standard Test Method for Determining Material Ignition and Flame Spread Properties

Main Features:
• The cabinet is made of stainless steel, corrosion-resistant and beautiful and easy to clean; The main frame have two separate parts of the burner frame and the specimen support framework. Two parts connected by bolts, and screws can be flexible mechanical adjustment.
• Ignition sources: radiation plate and imported a propane torch. Precise control of the flame height
• Burner, (200 ± 10) mm long holes ceramic tube,
• Cylinder type pilot burner flame support IMO standard automatic impact test; Optional
• Double grid and an enlarged perspective mirror observe the flame spread , it is user-friendly
• Radiation plate temperature controller: prevent flames turned the heat radiating plate rear side;
• Flow controller can easily test content of methane in the test gas flame heat
• Gas supply: with a valve, zero-pressure valve, tempering valves, solenoid valves and a mixer, the mixed air and fuel gas supplied to the radiation plate.
• Providing a porous alignment plate and heat flow meter fixed on a sliding movement rail to detect heat flux if meet the standard requirements
• Equipped with an adjustable observation angle lens (750mm × 120mm), the test sample can rake through the glass mirror and observe the flame spread rate and by a foot switch, automatic record.
• Sample chimney equipped with compensating thermocouples.
• All radiant panel combustion control system safety explosion-proof, check valve, cut off the gas solenoid valve prevents the gas reflux
• The camera can observe a situation and save the test program (Optional)
• Measuring heat flow state within the range of the radiation plate for 50mm
• Data acquisition system can store the image length flame spread and combustion characteristics
• 19 “rack to measure the flame spread rate analysis, critical flow, heat release rate
• Radiation plate burner system is fully automated, with spark ignition and safety protect system;
• IMO program so that all calibration, test results print (IMO, ISO) easier (Optional)
