What is the E 84 tunnel test and how does it apply to flooring?
The E 84 Tunnel Test has been retired many years ago as a floor covering flammability test. However, it continues to be the most widely used surface flame spread test for wall and ceiling finishes. It was never designed to be a floor covering test and was only adopted for floors as an interim test method. THERE ARE NO CORRELATIONS BETWEEN E-84 DATA AND FLOORING RADIANT PANEL DATA, i.e. a Class A in the E 84 Tunnel Test does not imply a Class I rating in the ASTM E 648, or vice versa.
