ISO 12136 Lab Fire Testing Equipment Fire Propagation Apparatus /
FPA
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.
