- Class B: In medium fire circumstances, these materials will hold steady for up to 1 hour and not ignite. They also will not allow the flame to spread beyond 8 feet. Quite impressive is the fact that they can resist 8 cycles of gas flame turned on one after the other.
- Class C: These are materials that do not have the best defense against flames. The flames cannot spread beyond 13 feet and they can offer resistance to ignition for up to 20 minutes. While these materials are the most flammable class, they can take on 3 cycles of gas flames without igniting.
