Standard test for determining relative combustibility. The flame spread of a tested material is rated relative to red oak (flame spread = 100).
Measurement of the flame propagation along the surface of a material.
Classification indicating propagation of flame across a sample compared to flame propagation across concrete panels and red oak. Results are obtained through an ASTM E84 or UL723 test.
Per ASTM E 84, a measure of relative combustibility. The flame spread of a tested material is rated relative to asbestos cement board Flame spread = 0) and red oak flooring Flame spread = 100).
The rate at which flame spreads.
