Evaluate fire performance of materials to ensure safety!

Use this test method to determine the ignitability, heat release rate, mass loss rates, effective heat of combustion, and visible smoke development of materials and products.

The results of the NFPA 271 test method are very useful in evaluating materials or products, mathematical fire modeling, design of new materials or products and in research and development. The method measures the response of materials to levels of radiant heating with or without an external igniter.

Formerly NFPA 264.
