EN 45545 Spread of Flame Tester
Spread of Flame Tester With Computer and standard test software control
Product Introduction of Kis ntawm Nplaim Tester
Sprea ntawm nplaim tester yog siv los ntsuam xyuas combustion yam ntxwv ntawm kev tsheb nqaj hlau cov ntaub ntawv thiab xa cov ntaub ntawv thiab kev ntsuas kis tus nqi ntawm nplaim, nplaim rau ignition los ntawm mus, CFE (Critical Flux ntawm Extinguishment) thiab tag nrho cov tshav kub tso tawm. Qhov no xeem txoj kev yog originated ntawm ISO 5658-2 (Cov tshuaj tiv thaiv rau hluav taws kub testsSpread ntawm flame- Part 2 Lateral kis rau lub tsev khoom nyob rau hauv txoj kev configuration) thiab ntsuas combustion yam ntxwv ntawm ntsug tshem me me (155mmX800mm).

Khoom Performance yam ntxwv ntawm Kis ntawm Nplaim Tester
1. Qhov kev kuaj ntsuas muaj plaub lub ntsiab Cheebtsam: ib tug txheej ntawm hluav taws xob phaj nkhaus thiab ib co ntawm cov qauv nkhaus, uas yog kev cob cog rua ua ke rau daim yuav tsum tau qauv nrog tawg phaj, qauv bracket thiab tiv cav tseb burner.
2. Lub tawg phaj muab ib tug tawg nto txog 480 hli X 280 hli, thiab cov hlau screen yog muab rau cov tawg pem hauv ntej kom ua rau kom cov tawg.
3. Cua qhov chaw ntawm hluav taws xob phaj yog muab los ntawm blower, thiab zaus converter yog siv los tswj nws.
4. Siv hluav taws roj zeb loj txaus maub los mus tswj cov pa roj qhov twg los, muab kev koom tes nrog Venturi tov khoom, tov nrog huab cua, thiab muab combustion roj qhov twg los rau tawg phaj.
5. Muab ib tug ntxeem tau calibration phaj thiab tsiv khiav ntawm ib tug zawv zawg tshav kub flow meter yuav ntes seb lub tshav kub tawg flux raws li cov kev cai ntawm tus txheej txheem.
6. Dej-txias thaum tshav kub kub tawg flux sensor, uas yog siv los ntsuas lub tshav kub tawg flux nkhaus ntawm hluav taws xob phaj.
7. Portable dej txias circulating ntaus ntawv yuav noj tam sim ntawd tus nto tshav kub ntawm tshav kub flow meter.
8. Cov hub raj burner yuav ncaj qha ua rau ntawm qhov chaw ntawm lub xeem qauv los ntawm qhib hluav taws.
9. rotor flowmeter yuav muab mixed combustion roj rau tej hub raj burner.
10. pawg khiav maub los tau yooj yim ntsuas lub tshav kub ntawm methane ntawm xab lub tseem ceeb heev thaum tshav kub kub flux.
11. Raws li IMO xeem qauv, thermocouple pab kiag li lawm yuav tau muab los ntsuas kub tso tawm tus nqi thiab lwm yam kev tsis.
12. Lub methane calibration burner thiab methane loj txaus maub los yuav muab 1KW thiab 3KW nplaim taws kub.
13. Thaum lub sij hawm lub xeem, lub koob yees duab yuav soj ntsuam thiab txuag lub ntsuas lub xeev nyob rau hauv qhov kev pab cuam.
14. nruab nrog ib lub-adjustable soj daim iav, cov nplaim taws kis tus nqi yuav tsum tau cai los ntawm lub khob iav thiab cov qauv sua thaum lub sij hawm lub xeem, thiab yuav muab sau tseg cia los ntawm ko taw mus.
15. Computer thiab txheem xeem software yog siv los tswj tus xeem txheej txheem.
Product Feature of Kis ntawm Nplaim 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.
