This part of BS8524 gives recommendations for the application, installation and maintenance of active fire curtain barrier assemblies. It is applicable only to active fire curtain barrier assemblies conforming to BS8524‑1:2013 that are designed to provide fire resistance or fire and smoke resistance. NOTE Smoke barriers, used solely for smoke control, are covered by BSEN12101‑1. Such smoke barriers are not considered to be active fire curtain barrier assemblies within the scope of BS8524. This part of BS8524 is also intended to provide guidance and recommendations for designers, specifiers (e.g. architects, fire engineers), approving authorities, installers and maintainers for the following: creating compartmentation; creating protected routes for the purpose of means of escape; providing protection at the location of non-fire-resisting elements, e.g. in front of non-fire-resisting glazing and doorsets, where required for compartmentation or protecting means of escape; providing a fire- and smoke-resistant barrier in conjunction with non-smoke rated products protecting openings to reduce leakage of smoke.
