BS 476-22：Fire Tests on Building Materials and Structures Part 22: Methods for Determination of the Fire Resistance of Non- Load bearing Elements of Construction
Abstract 摘要
This British Standard, a part of the BS 476 series, describes procedures for determining the fire resistance of non-loadbearing elements of building construction when subjected to the heating and pressure conditions.
This British Standard 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.
Appendix A to this standard 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.
