British Standard: BS476-20 – Fire resistance testing of building materials

The following content will explain the fire resistance test standard BS 476-20 for building materials:

 BS 476-20 Fire resistance test of building materials – Standard name:

• BS 476-20 Fire Testing of Building Materials and Building Components – Part 20. Method for determination of fire resistance of building elements (General Principles

• Fire Tests on Building materials and structures – Part 20. Method of test for determination of the fire resistance of elements of construction (General principles)

BS 476-20 Fire resistance testing of building materials - Overview of the standard

• BS 476-20 is mainly used to evaluate the fire resistance of building materials under high temperature conditions. It is mainly used for non-combustible materials, such as gypsum boards, ceilings, suspended ceilings, partition walls and partitions, etc.
