• Foams
• Expand
• Exhibit Intumescence
• As a result of this expansion and/or intumesence,
  these samples tend to
• Extinguish the Pilot Burner Flame
• Redirect the Pilot Burner Flame
• Expand in to the Pilot Burner Flame
• This may also occur with Cloth type Materials

Testing

• Silicone Impregnated Fiberglass Insulation
• Purpose Evaluate a 60-second pilot burner flame
  impingement versus 15 and 30 seconds.
• Initial testing has shown that a 60-second flame
  exposure results in no after flame time and no
  flame propagation.

• Ongoing support with ACOs and Labs for compliance
  checks
• Continued support for Labs experiencing problems
  (a.k.a., Radiant Panel Help Desk)
• Comparison testing with other Labs on specific
  materials
