This draft Standard describes procedures for determining the fire resistance of non-load bearing elements of building construction when subjected to the heating and pressure conditions specified in clause (2/1) .
It applies to fully insulated, semi-insulated and non-insulated vertical partitions of door and window assemblies (except for extinguishing systems united within ducts) attached to roof structures and to integrated elements of the building. The mentioned methods explain the appropriate methods for normal combinations of these elements.
Worth mentioning is that this draft standard is technically identical with BS 476-22/1987 (confirmed 2017)
