Product introduction:
This test method is to ignite the sample in the combustion chamber,
and the ignition source is the gas radiant plate and the
medium-sized gas burner.
The radiation intensity of the radiant plate is 32.5kw/m2 (surface)
at the distance of 75mm, and the flame height of the blowtorch is
75-100mm, which is applied to the sample in the same direction as
the radiant plate. The sample was exposed to the radiant heat
source plate for 10min. Record the flame propagation of the sample
for 1.5 minutes and 10 minutes. The test results are divided into
four grades. Grade 4 materials have high fire risk and are not
allowed to be used as building materials.
Standard:
BS476-7:
