IMO Flame Spread Test Apparatus

LS-ISO5658-2 IMO Flame Spread Test Apparatus is engineered in compliance with ISO 5658-2:2006, IMO FTP Code Resolution A.653(16), and ASTM E1317:2019 standards. This apparatus evaluates lateral flame propagation properties of building products to determine flame spread rate and fire retardant performance. The system utilizes a gas radiant plate for sample heating with integrated heat flow meter calibration. Test specimens are positioned vertically adjacent to the radiation plate, exposed to calibrated radiant flux in a controlled environment. A pilot flame ignites the sample surface without direct contact, initiating combustion. The apparatus records flame front progression horizontally across the sample surface, measuring combustion distance versus elapsed time. Additional parameters include ignition heat, sustained combustion heat, critical heat flux, average sustained burn calories, and total heat release.
