Flammability Tester Fire Propagation Test Apparatus
Application:
This method is applicable to determine surface burning characteristics of building materials and flame propagation rate of exposed surfaces such as walls and ceilings (including solid plastics), at the same time measure smoke density.
This test method applies to the exposed surface which includes ceiling or walls, provided that the materials or the whole assembly, with its own structural quality or the aspect in which is tested and intended to use is able to support itself in position or being supported during the period of test. The method is used to determine the corresponding burning behavior of the material by observing the flame spread along the test specimen. Reports are made for the flame spread and smoke density developed and it is not necessarily a relationship between the two measurements.
Standard:
ASTM E84: standard test method for surface burning characteristics of building materials
UL723: test for surface burning characteristics of building materials
