BS 476-23:1987

This standard BS 476-23:1987 Fire tests on building materials and structures is classified in these ICS categories:

• 13.220.50 Fire-resistance of building materials and elements

This Part of BS 476 describes procedures for determining the contribution made by components to the total fire resistance of a structure or other elements used in conjunction with them when subjected to the relevant heating and pressure conditions specified in BS 476-20. This Part provides the requirements for specimen selection and/or its design and construction, the edge conditions, the equipment including any special apparatus or instrumentation, and the procedures and criteria as they apply to components which make a contribution to the fire resistance of a complete assembly. The methods are applicable to suspended ceilings protecting steel beams and intumescent seals for use in conjunction with single-acting, latched timber fire resisting door assemblies.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.

Detailed test requirements for the contribution made by suspended ceilings to beams and by intumescent seals to doorsets and shutter assemblies.
