IMO Resolution A.653 Fire Testing Equipment Laboratory Spread of
Flame Test Machine
Application:
This instrument uses a gas-fired radiant heat panel with pilot
flame ignition to ignite a test specimen.
Following ignition, any flame front which develops is noted and a
record is made of the progression of the flame front horizontally
along the length of the specimen in terms of the time it takes to
travel to various distances.
The results are expressed in terms of the flame spread
distance/time history, the flame front velocity versus heat flux,
the critical heat flux at extinguishment and the average heat for
sustained burning.
To meet the IMO specification a stack is fitted complete with
thermopile for estimating heat release rate.
The apparatus is supplied with all necessary controls, flux meter
and specimen holder.
The complete test apparatus consists essentially of three main
components, a radiant panel support framework and a specimen
support framework which are linked together to bring the test
specimen into the required configuration in relation to the radiant
panel, and the specimen holder, which carries the test specimen.
The radiant burner system is fully automatic, with spark ignition
and safety interlocks.
Description:
It’s suitable to evaluate burning characteristics of construction
materials and measure the spread of flame,flame condition of
ignition at multiple distances,critical flux,and total heat release
value.It can also measure the burning characteristics of vertical
specimen.After recording time of ignition and extinguishment at
each distance,we can calculate the flame spread rate.
Other test results include:ignition heat(MJ/m2),continuous burning
heat(MJ/m2),critical flux(MJ/m2),average heat of continuous
burning(MJ/m2),total heat release value(kW).
Standards:

Vertical Configuration
ASTM E 1321 Standard Test Method for Determining Material Ignition
and Flame Spread Properties
Features:
1. All controlling system is Ex-proof;
2. Cylinder type pilot burner can support automatic flame
impingement by IMO standard;
3. Dual layers grid and enlarged lenses make users easy to inspect
the flame spread situation;
4. Temperature controller of radiant panel can be used to measure
internal temperature of light source
plate. It can close Solenoid value automatically when flame reflux;
5. Large flow controller can easily measure methane content when
measuring critical heat flux of gas;
6. All Ex-proof parts in radiant panel combustion controlling
system can prevent gas reflux,like check
value and solenoid value;
7. Camera can observe and store test procedures at certain program;
8. Measure heat flux condition of radiant panel in 50mm;
9. Data acquisition system can store images of flame spread length
and burning characteristics;
10. 19°analyzing frame can measure flame spread rate,critical
flux,heat release rate;
11. IMO program makes all calibration,test and test result printed
(IMO,ISO) easier.
