BS 476-4 Micro Computer Non-Combustibility for Material
Application:
When a certain amount of gas is supplied to the box and the
standard ignition source is used to ignite the flame, this
instrument can be used to test the ability of the vertical flame
propagation to be restrained under the standard conditions of the
vertically installed bundles of wire, cable or optical fiber cable.
