Testing device Spread of Flame ISO 5658-2 / IMO A 653(16)

 

 

Characteristics

  • Lateral spread of flame on vertically arranged construction products

The results of this testing procedure are used as a basis for evaluating the burning behavior of a lateral flame which spreads along a specimen. The heat radiation which a radiant heater applies to a specimen simulates the probable degree of stress that acts upon a specimen in a fire scenario. The sample is placed in a horizontal position under the gas-heated radiant heater that is inclined by 15 +/- 3° against the horizontal line. The sample is exposed to a certain heat stream. A pilot flame is brought into contact with the hot end of the sample. After ignition any flame front that forms is registered and its horizontal spread along the length of the specimen is recorded as the time the flame front needs for spreading over defined distances. For the IMO standard an exhaust flue with thermocouples is used to calculate the maximum heat release rate and the released total amount of heat. Controlling and measurement data recording is done with the software. It provides the calibration, valve control, preheating and CHF calculation.
