ASTM D3675 – Surface Flammability of Flexible Cellular Materials

Standard: ASTM D3675 Standard Test Method for Surface Flammability of Flexible Cellular Materials Using a Radiant Heat Energy Source

Scope: Per ASTM D3675: "This is a fire test response standard [and] describes the measurement of surface flammability of flexible cellular materials."

Products: Plastics, flexible cellular materials

Procedure: Per ASTM D3675: "This test method of measuring surface flammability of flexible cellular materials employs a radiant panel heat source consisting of a 300 by 460-mm (12 by 18-in.) panel in front of which an inclined 150 by 460-mm (6 by 18-in.) specimen of the material is placed. The orientation of the specimen is such that ignition is forced near its upper edge and the flame front progresses downward. Factors derived from the rate of progress of the flame front and the rate of heat liberated by the material under test are combined to provide a radiant panel index."

Result: Testing results in determination of a Radiant Panel Index
