BS 476-22 Fire Resistance Test to Building Material – Standard Brief
BS 476-22 describes procedures for determining the fire resistance of non-loadbearing elements of building construction when subjected to the heating and pressure conditions specified in BS 476-20. This Part is applicable to vertical partitions, to fully insulated, partially insulated and uninsulated vertical doorsets and shutter assemblies (except fire dampers incorporated in ducts), to ceiling membranes, and to glazed elements. The methods described are appropriate to normal combinations of these elements.
BS 476-22 has been prepared under the direction of the Fire Standards Committee, and describes the procedures for determining the fire resistance of non-loadbearing elements of building construction. This Part should be read in conjunction with BS 476-20 which describes the general principles for these methods.
This Part has been prepared in such a way as to allow reference to be made to the appropriate method of determining the fire resistance of the designated element by clause number only. Therefore clauses 5 to 7 are selfcontained and cross refer to BS 476-20 where necessary.
Methods for determining the fire resistance of loadbearing elements that have a finite fire resistance and of components that make a contribution to the fire resistance of a structure are described in BS 476-21 and 23 respectively. The general changes made to the methods described in this Part compared with BS 476-8 are described in the foreword to BS 476-20. Appendix A gives guidance and background information which will assist the designer and the testing laboratory to select and evaluate specimens that are representative of “in use” situations.
The methods described are not relevant to the assessment of the penetration of smoke under cold and/or medium temperature conditions, and for such
information on doorsets and shutter assemblies, the methods described in BS 476-31.1 and in other Sections of Part 31 (in preparation) are applicable.
