This method covers a laboratory Procedure for testing of bunch cables mounted vertically to determine their relative ability to resist flame prorogation. The test is conducted in open air environment only.
For certain locations it may be important to use a cable which retards flame in case of fire and is self – extinguishing when the source of fire is removed. This test is carried out on finished cables to veri
Smoke Density Apparatus is used for measuring & observing the relative amount (Density) of smoke produced by the burning (combustion) or decomposition of Plastic, Cables etc. under controlled conditions.
