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

Bidhaa Utendaji tabia ya Kuenea kwa Flame Tester
1. mtihani chombo inajumuisha vipengele vikuu vinne: seti ya mionzi sahani mabano na seti ya mabano sampuli, ambayo ni kushikamana pamoja na kuunda muundo required kwa sahani mionzi, sampuli mabano na moto burner.
2. sahani mionzi hutoa mionzi ya uso wa juu 480 mm X 280 mm, na screen ya chuma inatolewa kwa mionzi mbele ya kuongeza mnururisho.
3. Air chanzo cha sahani mionzi hutolewa na blower, na frequency kubadilisha hutumika kudhibiti yake.
4. Matumizi propane habari kati yake mtawala kudhibiti gesi chanzo, kushirikiana na Venturi mixer, kuchanganya na hewa, na kutoa mwako gesi chanzo kwa sahani mionzi.
5. Kutoa porous calibration sahani na kusonga wimbo wa sliding joto mita kati yake inaweza kuchunguza kama joto mionzi flux hukutana mahitaji ya kiwango.
6. Maji-kilichopozwa joto mionzi flux sensor, ambayo ni kutumika kupima joto mionzi flux Curve ya sahani mionzi.
7. Portable maji baridi mzunguko kifaa wanaweza kuchukua mbali ya uso joto ya joto kati yake mita.
8. kauri tube burner unaweza moja kwa moja hatua juu ya uso wa mtihani sampuli na moto wazi.
9. Rotor flowmeter inaweza kutoa mchanganyiko mwako gesi kwa kauri tube burner.
10. Misa kati yake mtawala kwa urahisi kupima joto ya methane kwa kupima muhimu joto flux.
11. Kwa mujibu wa IMO viwango mtihani, vifaa thermocouple inaweza kutolewa kupima joto cha kutolewa na takwimu zingine husika.
12. methane calibration burner na wingi methane mtiririko mtawala inaweza kutoa 1KW na 3KW moto joto.
13. Wakati wa mtihani, kamera inaweza kuchunguza na kuokoa hali ya kipimo katika mpango.
14. Pamoja na vifaa pembeni-adjustable uchunguzi kioo, moto kuenea cha yanaweza kuzingatiwa kwa njia kioo kioo na sampuli reki wakati wa mtihani, na inaweza kumbukumbu moja kwa moja na kubadili mguu.
15. Computer na kiwango mtihani programu zinazotumika kudhibiti mchakato mtihani.
Product Feature of Kuenea kwa 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.
