BS 476-22 Fire test to non-loadbearing elements of construction-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.
