Flame Spread Rate & Critical Heat Flux Tester Spread of Flame Test Equipment for Construction Material Burning Characteristic Test

This IMO-compliant spread of flame test apparatus is engineered to evaluate the burning behavior of construction and marine transport materials. It performs a lateral flame spread test on vertically mounted specimens, records ignition and extinction time at different distances, and calculates the flame spread rate. The instrument measures critical heat flux, ignition heat, continuous burning heat, and total heat release value as required by fire safety codes. Featuring an explosion-proof gas circuit, radiant heating panel, and visual recording function, it fulfills the test requirements of ISO 5658-2 and ASTM E1321 for marine and construction fire certification.

• Explosion-proof construction: All control and gas circuit components are explosion-proof rated, with check valve and solenoid valve dual protection against gas reverse flow, meeting marine safety requirements.
• Standardized ignition burner: Cylindrical ignition burner conforms to IMO specifications for standardized automatic flame impingement.
• Superior flame observation: Double grid observation structure and large lens deliver excellent visibility for capturing flame spread status.
• Independent radiant panel control: Dedicated temperature control unit enables real-time temperature monitoring and automatic gas cut-off for flame backflow protection.
• High-precision flow control: Large flow controller supports methane testing when measuring critical heat flux of gas samples.
• Automated data acquisition: Data acquisition module automatically archives flame spread images and burning characteristic data for certification audit.
• 19° analysis frame: Supports synchronous testing of flame spread rate, critical heat flux, and heat release rate.
• IMO software package: Streamlines calibration, test runs, and formal test report printing for marine product approval.

Designed primarily for marine outfitting manufacturers, shipyards, marine material certification bodies, offshore equipment suppliers, building fire safety laboratories, and public transport interior material factories. The apparatus supports fire reaction certification testing for ship interior panels, vertical building boards, and other transport products.
