BS 476-6 Building Materials Flame Spread Testing Equipment With Stainless Steel Support Frame

Building Materials Flame Spread Testing Equipment

Product Introduction

BS 476 part 6 specifies a method of test, the result being expressed as a fire propagation index, Building Materials Flame Spread Tester BS 476-6 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.
