Flame spread and smoke developed
recorded while material remained in the original
test position. Ignition of molten residue on
the furnace floor resulted in flame travel
equivalent to calculated flame spread index of 10
and smoke developed index of 200. |

Flame spread and smoke developed
recorded while material remained in the original
test position. Ignition of molten residue on
the furnace floor resulted in flame travel
equivalent to calculated flame spread index of 40
and smoke developed index of 450. |

### |
Flame spread and smoke developed
recorded while material remained in the original
test position. Ignition of molten residue on
the furnace floor resulted in flame travel
equivalent to calculated flame spread index of 80
