28、r adjoining buildingNOTE 1 Compartmentation is mainly employed to assist the emergency services by confining the fire within a fire resisting enclosure. In some instances it is employed to assist means of escape in buildings where evacuation may be delayed, for example, where phased evacuation polic
29、y has been applied in premises, such as hospitals and care homes, or where a policy of non-evacuation (e.g. “defend in place”) is employed as in certain designs of flat complexes.NOTE 2 Fire enclosures specifically for the purpose of means of escape, such as lobby protection to stairways and enclosu
30、re of special risks, are not regarded as compartments and normally have a lesser fire time and may employ passive smoke resistance measures.3.5 deploymentmovement of a barrier from its retracted position to its fire operational position3.6 fire operational positionposition of a fire curtain barrier

40、quirementsNOTE The active fire curtain barrier assembly requirements are intended to provide the fire engineer and/or designer with an alternative to fire doors, shutters, walls and ceilings which fulfil the fire separation design requirements for life safety and property protection. Compliance with
41、 this specification does not necessarily, by itself, ensure fitness for purpose for an application, as defined in ISO/IEC Guide 2:1996.The building design parameters will dictate the minimum classification and performance of active fire curtain barrier assemblies that can be used in any particular a
42、pplication. The criteria for the correct choice of active fire curtain barrier assembly should take into account the total system, function and location requirements without hindering the means of escape or endangering the occupants. Applications are based on a full series of tests on the complete a
43、ssembly (including fire tests) as it is to be installed.4.1 Installation4.1.1 GeneralThe active fire curtain barrier assembly shall be installed such that its deployment is not obstructed. The inclusion of an additional zone to compensate for the deflection of the barrier due to fire pressure shall
44、be taken into account (see Annex A).NOTE Care should be taken to ensure that any adjacent surfaces which form part of the barrier to fire, e.g. false ceilings or fittings, have at least equivalent properties as the fire/smoke barrier, e.g. resistance to temperature and permeability.4.1.2 Side retent
45、ionSide retention shall be installed within the buildings structure unless measures are taken to protect the side retention from mechanical damage by using, for example bollards (see Figure 1).Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 06/12/2007 07:10, Uncontrolled Copy, (c) BSI BSI 200
