EN 45545 Spread of Flame Tester
Spread of Flame Tester With Computer and standard test software control
Product Introduction of Ukwanda Flame 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).

Iimpawu Product Performance of Ukwanda Flame Tester
1. Isixhobo uvavanyo iqulathe amacandelo ezine eziphambili: iseti radiation izibiyeli ipleyiti kunye iseti izibiyeli isampula, abaqhagamshelwe ukuze zenze isakhiwo efunekayo nge plate radiation, isibiyeli isampula kunye ucinezelo sokukhuphela.
2. I-plate radiation inika umphezulu radiation omalunga-480 mm X-280 mm, kwaye metal screen inikezelwe kwi phambi radiation ukwandisa kwimitha.
3. umthombo Air of ipleyiti radiation ibonelelwa blower, kwaye rhoqo converter isetyenziselwa kusilawula.
4. Sebenzisa propane, ngobuninzi flow isilawuli ukulawula umthombo nerhasi, basebenzisane Venturi sokuxuba, mix kunye nomoya, kunye nokunika umthombo gas yokutsha ngenxa plate radiation.
5. Ukubonelela umlinganiselo kwimibhobho ipleyiti aneentunja neshukumayo track ngokokushiyana nobushushu flow imitha bangabhaqa ukuba wobhobhozayo radiation ubushushu idibana iimfuno umgangatho.
6. Water-zipholile radiation ubushushu sensor wampompoza, esetyenziselwa ukulinganisa radiation bubushushu obhobhozayo kwigophe le plate radiation.
7. amanzi eziphathekayo okupholisa isixhobo elijikeleza kungathatha ubushushu umphezulu imitha obushushu.
8. tube inkcukacha yodongwe abanokusebenza ngqo phezu komhlaba kovavanyo isampuli ngomlilo evulekileyo.
9. Rotor flowmeter unganikeza irhasi yokutsha mixed for yodongwe ityhubhu sokukhuphela.
10. Mass flow isilawuli lula umlinganiselo ubushushu methane ngokulinganisa ebalulekileyo ubushushu ukubhobhoza.
11. Ngokutsho Imo imigangatho yovavanyo, thermocouple izixhobo inganikezelwa ukulinganisa ukukhululwa rate ubushushu kunye nezinye iparameters ezinxulumeneyo.
12. I-PowerPoint methane yamaqondo methane mass flow isilawuli unganikeza nelangatye lobushushu 1KW kunye 3KW.
13. Ngexesha uvavanyo, ikhamera nga bagcine kwaye ukusindisa isimo womlinganiselo kule program.
14. nee-engile-adjustable ukuqwalaselwa esipilini, idangatye ukusasazeka izinga inokubonakalisa ngokusebenzisa iglasi esipilini ngeharika isampuli ngexesha lovavanyo, kwaye zibhalwe ngokuzenzekelayo yi iswitshi ngeenyawo.
15. Computer software standard uvavanyo zisetyenziswa ukulawula inkqubo yovavanyo.
Product Feature of Ukwanda Flame 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.
