ASTM E1317 Electronic Radiant Panel IMO Flame Spread Testing Equipment ISO 5658-2
I. Product introduction:
The flame extension tester was developed and produced according to the ISO5658-2 standard, while meeting the requirements of IMO FTP Code Resolution a. 653(16) and ASTM E 1317.For the determination of transverse flame propagation performance of building products, flame propagation performance / flame spread speed can be used to assess the flame retardant performance of materials.
The equipment through the gas radiation heat radiation board, using imported heat flow meter calibration radiation heat, lit by mixing gas burner sample to test the material in the case of certain radiation heat of combustion; Sample is exposed to the area where the radiation flux is clearly calibrated, Measurement of ignition time, flame spread and final extinction time. The test sample is placed in a vertical position, Adjacent radiant panel, Exposure to areas with clear calibration of radiant flux.The ignition flame is close to the test sample, but does not contact the test sample, the hot end of sample is ignited by an evaporation gas on the surface, after ignition, record the development of flame forward, and record the time when flame forward is burned on the surface of the sample to each calibration distance.Then test materials include the ignition heat, continuous combustion heat, critical flow rate, average heat of continuous combustion, total heat release quantity and other related parameters.
ISO 5658-2: flame propagation, part 2: extent of flame spread on the side of the building product.
GB/T 28752-2012: horizontal spreading test method for flame on vertical surface.
IMO FTP Code Resolution a. 653(16) : proposal for flammability test procedure for bulkhead, ceiling and deck materials (optional)
ASTM E 1317: standard test method for flammability of ship surface coatings.
