Introduction

Radiant Panel Flame Spread Tester is a device to measure the surface flammability of Building product (ASTM E 162) and cellular plastics (ASTM D 3675) using gas-fired Radiant heat panel.

It measures flame propagation, critical heat flux (CHF) and heat release rate (kW / m2).

▣ The radiating panel consists of a porous refractory material vertically attached to a cast iron frame with exposed radiating surfaces of 305 (W) x 457 (H) mm and is designed to operate at 815 ° C.

▣ Air is supplied to the Radiant Panel by using blower with filter.

▣ Auto ignition is possible by Pilot Burner.

▣ Calibration Burner is placed uniformly at 16mm intervals with 1.8mm holes along the center line.

▣ Exhaust device, that has 0.5 m / s air speed of air stack, is attached .

▣ In order to control the surface heat of the radiation panel, a radiation pyrometer with an accuracy within ± 5℃ was used, which is suitable for observing an area of 250mm in diameter at a distance of about 1.4m and a range of 180 ℃ ~ 230 ℃ (black body temperature)

▣ Thermocouple for measuring stack temperature is equipped.

▣ Medtherm’s Heat Flux Meter is used to measure Radiant Panel radiant heat (0 ~ 100kW / m2).

▣ It is programmed for easy automatic control and measurement using DAQ System.

▣ Exposure time and whether the specimen

was completely destroyed or was expose for 15min.

▣ Average radiant panel index (Is) for each set of specimens,  rounded to the nearest multiple of five.

▣ The simple ratio of a temperature rise of 100℃ to the heat input in  kilowatts producing it. (Beta)

▣ Flame spread factor (Fs)

▣ Heat evolution factor (Q)
