EN 45545 Spread of Flame Tester
Spread of Flame Tester With Computer and standard test software control
Product Introduction of Sumebarna hirupkeun tester
Sprea of flame tester is used to evaluate combustion characteristics of rail materials and ship materials and measures spread rate of flame, flame for ignition by distances, CFE (Critical Flux at Extinguishment) and total heat release. This test method is originated from ISO 5658-2 (Reaction to fire testsSpread of flame- Part 2 Lateral spread on building products in vertical configuration) and measures combustion characteristics of vertical specimen (155mmX800mm).

Product Feature of Sumebarna hirupkeun tester
The apparatus consists of a radiant panel having dimensions of 280 x 483 mm, mounted vertically, and making an angle of 15° with the specimen.
The orientation of the panel results in an incident radiant flux that decreases from 50 kW/m² at one end to approximately 1 kW/m² at the other end of the specimen.
The sample is ignited by a non-impinging, gas/air pilot flame.
Viewing rakes placed at a 50-mm spacing along the specimen.
Heat Flux Meter - for setting the irradiance level at the surface of the specimens, the range from 0-50KW/m2.
Portable water cooling system without need for waterworks and plumbing when using the Heat Flux meter.
The radiant burner system is fully automatic, with spark ignition and safety interlocks.
MFC (Mass Flow Controller) to easily measure the heat amount of methane gas in measuring critical heat flux.
Camcorder to observe and save test conditions in a program during tests.
To meet the IMO specification a stack is fitted complete with thermopile for estimating heat release rate.
Records the spread rate of flame after this records ignition and extinguishment time of flame for each distance of specimens. And the other test results is Heat for ignition (MJ/㎡), Heat for sustained burning (MJ/㎡), Critical flux at extinguishment (kW/㎡), Average heat for sustained burning (MJ/㎡), Total heat release (kW),Peak heat release rate (kW) .
How is flame spread measured?
Flame spread rating is calculated by the distance a flame travels across a material, divided by the amount of time it takes to travel that distance. Testing for flame spread rating involves burning materials under controlled conditions and measuring the speed and extent of flame spread.
What is spread of flame test?
Flame spread tests aim at measuring the tendency of a flame to propagate over a substrate and directly correlate to surface flame propagation in a real fire scenario.
