This part of BS 8524 gives recommendations for the application, installation and maintenance of active fire curtain barrier assemblies. It is applicable to active fire curtain barrier assemblies conforming to BS 8524‑1:2025 that are designed to provide fire resistance or fire and smoke resistance.
NOTE Smoke barriers, used solely for smoke control, are covered by BS EN 12101‑1. Such smoke barriers are not considered to be active fire curtain barrier assemblies within the scope of the BS 8524 series.
This part of BS 8524 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; and
providing a fire- and smoke-resisting barrier in conjunction with non‑fire- and non‑smoke‑resisting products protecting openings to reduce leakage of smoke.
