Spread of Flame Test Apparatus ISO 5658-2 ASTM E1321 Building & Transport Materials Flame Spread Tester

This spread of flame test apparatus is engineered to assess the fire reaction performance of construction and transport materials. It conducts both horizontal and vertical flame spread tests, records ignition and extinguishment times at preset intervals, automatically calculates flame spread rate, and collects key thermal data including ignition heat, continuous burning heat, critical heat flux and total heat release. Equipped with an explosion-proof control system, video recording module and 19° test frame, the instrument fully supports calibration and testing in compliance with ISO 5658-2 and ASTM E1321. All test records, images and reports can be exported and printed directly.

• 1.Full explosion-proof control circuit and gas pipeline components, including check valves and solenoid valves, effectively prevent gas backflow for high operation safety.
• 2.Cylindrical pilot burner strictly follows IMO requirements to realize standard automatic flame impingement.
• 3.Double-layer observation grid and enlarged viewing lens offer a clear view to observe the whole flame propagation process.
• 4.Radiant panel temperature controller monitors the internal temperature of the heat source plate and cuts off gas supply automatically once flame backflow occurs.
• 5.High-range flow controller supports methane measurement for critical heat flux testing of gaseous samples.
• 6.Built-in acquisition system captures and saves flame spread footage and burning characteristic data throughout the test.
• 7.19° analysis frame supports multi-index synchronous measurement: flame spread rate, critical flux and heat release rate.
• 8.Dedicated IMO software simplifies calibration operation, test running and standardized report output.

It is widely adopted by fire testing laboratories, material certification institutes, ship and transport equipment manufacturers, building material factories, interior decoration and marine material suppliers for flame propagation and fire hazard evaluation of vertical construction products, marine structural materials, interior panels and transport-related components.
