fire resistance test machine

Hongswell's Fire Resistance Assemblies Tester is included in both the IEEE 1202 and IEEE 383 standards. This test method is proceed in a chamber with a set volume for 20 minutes. During the 20 minutes, a sample cable is ignited with theoretically 20kW(70,000Btu/hr) flame using an ignition source fixed in a vertical position. This equipment evaluates a spread of flame of single core cable or multi core cable. If user wants to measure H.R.R (Heat Release Rate), Smoke density
