Flammability Testing
    
  Using a testing device called a cone calorimeter, NIST researchers measure the heat-release rate and other flammability properties of materials.  Above, untreated polyurethane foam "catches fire" from a nearby heat source.  Below, foam treated with a novel clay-filled coating did not ignite when exposed to the same heat source. Instead, a fast-growing protective layer-called char-forms on the surface.
