ASTM E 84 - 06 ZY6256 Flammability Test Chamber Building Material UL723
Scope of application:
The experiment was conducted to determine the flame propagation rate of building materials (and to measure the concentration of smoke). The surface combustion of the test material was compared with the asbestos plywood and unprocessed red oak. Grade 0 is asbestos plywood, 100 grade unprocessed red oak floor material. The flame propagation rate ranges from 60 to 230. During this test, smoke produced during combustion was also measured and rated at the same level.
Meet the standard:
Test method for the surface combustion characteristics of ASTM E 84-06 building materials.
ASTM E 84-06 standard test method for surface burning characteristics of building materials.
Test method of surface combustion performance of the building materials.
UL723 test for surface burning characteristics of building materials.
