A list of organizations represented on this committee can beobtained on request to its secretary.Relationship with other publicationsThis British Standard has been developed from PAS 121, which will bewithdra

12、wn on 31 July 2013. This British Standard is published in two parts: Part 1: Specification; Part 2: Code of practice for application, installation and maintenance.Use of this documentIt has been assumed in the preparation of this British Standard that theexecution of its provisions will be entrusted

13、 to appropriately qualified andexperienced people, for whose use it has been produced.Assessed capability. Users of this British Standard are advised to consider thedesirability of sourcing active fire curtain barrier assemblies from suppliers whooperate quality systems that have been assessed and r

14、egistered against theappropriate standard in the BS EN ISO 9000 series by an accredited third-partycertification body.Installation and maintenance. Users of this British Standard are advised toconsider the desirability of third-party certification of installers and maintainersof active fire curtain

Users seeking assistance in identifyingappropriate conformity assessment bodies or schemes may ask BSI to forwardtheir enquiries to the relevant association.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Itsrequirements are e

16、xpressed in sentences in which the principal auxiliary verb is“should”.Commentary, explanation and general informative material is presented insmaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the nec

Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legalobligations.BRITISH STANDARDBS 8524-2:2013ii The British Standards Institution 20130 Introduction0.1 Role and use of barrier assembliesAs fire-separat

18、ing elements, barrier assemblies are required to provide two mainfunctions:a) to maintain any compartmentation of buildings needed to limit the spreadof fire and smoke;b) to allow access to protected escape routes, both vertical and horizontal,without any loss of fire resistance, and to limit smoke

19、entry into theseroutes, i.e. protected corridors and protected shafts.They can also be partially deployed to control the movement of fire effluentwithin buildings in the event of fire, prior to being fully deployed as a firebarrier.Recommended positions and ratings for fire-separating elements for m

20、eans ofescape purposes are given in BS 9999, BS 9991 and BS 7974. Therecommendations in BS 9999 and BS 9991 use a risk-based approach; those inBS 7974 are based on the principles of fire safety engineering.When used as part of a fire-engineered design solution, barrier assemblies canbecome a critica

21、l element of that design. If barrier assemblies do not deploy totheir operational position, the fire-engineered solution would be compromised.However, in the event that other fire protection systems or elements do notfunction, e.g. due to total power failure, the barriers in the fire-operationalposi

22、tion will provide fire separation.0.2 Application of barrier assembliesBarrier assemblies used in life safety and property protection applications can behorizontal, vertical or angled. Depending upon the application, they could beused to replace fire doors, roller shutters, non-load-bearing walls,no

23、n-load-bearing ceilings, glazed elements, etc. They could also be used to formfire separation, e.g. forming protected routes or lobbies. They can provide someof the functionality of a fire door, but when used only for fire and smokecontrol, as a fire door, then different requirements apply. These re

24、quirementswill be given in BS EN 16034 (currently in preparation as prEN 16034). Barrierassemblies can enable greater barrier widths and barrier movements using lessspace than other traditional methods.It is essential that any proposed use of barrier assemblies is assessed in thecontext of the build

25、ing use and perceived occupancy to ensure that it isultimately suitable and fit for purpose, taking into consideration such factors as:a) fire resistance;b) reaction to fire;c) smoke leakage;d) occupancy type and risk profile;e) occupancy load;f) means of escape for egress;g) ingress for fire and re

26、scue service;h) life safety and property protection objectives.BRITISH STANDARD BS 8524-2:2013 The British Standards Institution 2013 10.3 Heat transfer through barrier assembliesIn fire safety situations, it is often important to establish the heat transfer fromone side of the separating element to

27、 the other in order to calculate escaperoute sizes and safe operating distances. This is usually established usinginsulation data. Due to the difficulty of measuring insulation on some barrierassemblies, guidance on the use of radiation data as an alternative is given inthis standard.NOTE National b

28、uilding regulations (1 to 3) only apply to life safety. Higherperformance levels might be necessary for certain applications if property protectionis required.1 ScopeThis part of BS 8524 gives recommendations for the application, installation andmaintenance of active fire curtain barrier assemblies.

29、 It is applicable only toactive fire curtain barrier assemblies conforming to BS 8524-1:2013 that aredesigned 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 f

30、ire curtain barrier assemblieswithin the scope of BS 8524.This part of BS 8524 is also intended to provide guidance and recommendationsfor designers, specifiers (e.g. architects, fire engineers), approving authorities,installers and maintainers for the following:a) creating compartmentation;b) creat

31、ing protected routes for the purpose of means of escape;c) providing protection at the location of non-fire-resisting elements, e.g. infront of non-fire-resisting glazing and doorsets, where required forcompartmentation or protecting means of escape;d) providing a fire- and smoke-resistant barrier i

32、n conjunction with non-smokerated products protecting openings to reduce leakage of smoke.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in thisdocument and are indispensable for its application.
