automaticflameindustrial

The Radiant Test Device, in accordance with NF P 92-501, is designed to measure the reaction to fire behaviour of rigid materials or flexible materials thicker than 5mm when it is exposed to a 500w radiant heat source and ignition flame. • Stainless steel test chamber with a 25mm insulating non-combustible inner core, equipped with a transparent observation window. • Stainless steel tubular air inlet unit, equipped with a filter to shield the chamber from contaminants. • 45 degree test stand, equipped with a stainless steel indicator scale to calculate the flame spread distance. • France original Epiradiator heat radiation source, power rated at 500W, which radiant surface is made of a translucent vitreous fused silica disk of 100 mm diameter. • Power controller to control the radiation output and adjust the radiation flux of the Epiradiator. • Panel display of the operating power value of the Epiradiator, eliminating frequent calibration procedures. • Upper and lower stainless steel burners for ignition of volatile combustible gases. • Precise needle valve to control the flame height of the upper and lower burners, equipped with a flame height gauge. • Ignition device for convenient ignition of upper and lower burners prior to testing. • Standard copper disc calorimeter for calibration of the Epiradiator. • The copper disc calorimeter is 30mm in diameter and 5mm in thick which is oxygen-free copper made and the copper disc is set in a refractory plate, the surface of the copper disc is coated with black paint with an absorption rate of 0.96; the back of the disc is soldered with a 0.5mm diameter type K thermocouple for temperature measurement.
