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).
