The Flame Propagation Calorimeter (FPA) characterizes fire behavior in corresponding scale fire tests by measuring the combustibility characteristics of materials.

 

The main measured parameters include time to ignition, mass loss rate, heat release rate including chemical and convective heat release rate, and smoke generation rate.

 

The testing scope covers various materials, components, end products, and polymer materials, but it is not suitable for explosive objects.

 

The test results can be used to evaluate the inherent combustibility of materials and provide a basis for flame spread models, fire development models, hazard assessment, building and product design, and material development.
