Description:

This fire-test-response standard determines and quantifies material flammability characteristics, related to the propensity of materials to support fire propagation, by means of a fire propagation apparatus (FPA).The main parameters contains time to ignition,mass loss rate,heat release rate(chemical and convective) and smoke generation rate.The scope of testing is various materials,components and final products as well as many kinds of polymer materials,but not suitable for explosive objects.The test results of flame propagation calorimeter can evaluate specific material flammability, provide the necessary basis for the flame propagation speed and fire growth model, risk assessment, architecture and product design, and materials research and development.
