BS 476-6 Fire Propagation Index Tester

BS 476 part 6 specifies a method of test, the result being expressed as a fire propagation index, that provides a comparative measure of the contribution to the growth of fire made by an essentially flat material, composite or assembly. It is primarily intended for the assessment of the performance of internal wall and ceiling linings.​

Quantity:
  • GD-BS476-6
  • GOLD
  • 9031809090
