The Steiner Tunnel Test Furnace Horizontal Combustion Testing Apparatus is conformance to UL910,ASTM E84 and several standards;This test method is a 10-minute fire test response standard designed to provide comparative measurements of flame spread and smoke density over select grades of red oak and fiber cement board surfaces under specific fire exposure conditions.
The ASTME84 test method determines the relevant combustion characteristics of the sample by observing the flame propagation along the sample. The test report is expressed as the flame spread index and smoke development index.
FSI (Flame Spread Index) and SDI (Smoke Development Index) are important parameters for evaluating the fire protection grade of ASTM E 84 test.
