6、SupersessionThis British Standard supersedes BS 5357:1995, which is withdrawn.Information about this documentBS 5357 gives guidance to those responsible for installations involving the use of security glazing. In this revision, guidance has been updated to take account of the introduction of a numbe
7、r of new European Standards and other publicly available standards covering glass, windows and doors for security applications. The recommendations in this code, cover the mounting of security glazing so that it strongly resists dislodgement from its position when under attack and give guidance to e
8、nsure that the rest of the installation provides at least as high a level of protection as the security glazing itself. The recommendations apply to bullet-resistant glazing, glazing resistant to manual attack (formerly called “anti-bandit glazing”) and glazing subject to explosions. The principles
9、that the glazing should not be dislodged from its position under attack, and that the rest of the installation should offer at least equal protection, apply to all types of security glazing.It is essential that any installation complies with relevant fire regulations and that adequate means of escap
10、e from fire are provided. The purpose of this code is concerned with the protection of life, and aesthetic considerations are therefore, wherever necessary, subordinate to the needs of security.Product certification/inspection/testing. Users of this British Standard are advised to consider the desir
11、ability of third-party certification/inspection/testing of product conformity with this British Standard. Appropriate conformity attestation arrangements are described in the appropriate harmonized European Standard (e.g. EN 14449 for laminated and laminated safety glass). Users seeking assistance i
12、n identifying appropriate conformity assessment bodies or schemes may ask BSI to forward their enquiries to the relevant association.

13、 it were a specification and particular care should be taken to ensure that claims of compliance are not misleading.Any user claiming compliance with this British Standard is expected to be able to justify any course of action that deviates from its recommendations.It has been assumed in the prepara
14、tion of this British Standard that the execution of its provisions will be entrusted to appropriately qualified and experienced people, for whose use it has been produced.Presentational conventionsThe provisions in this standard are presented in roman (i.e. upright) type. Its recommendations are exp
15、ressed in sentences in which the principal auxiliary verb is “should”.Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element.The word “should” is used to express recommendations of this standard. The word “may” is use
16、d in the text to express permissibility, e.g. as an alternative to the primary recommendation of the clause. The word “can” is used to express possibility, e.g. a consequence of an action or an event.Notes and commentaries are provided throughout the text of this standard. Notes give references and
17、additional information that are important but do not form part of the recommendations.

32、rovide at least the equivalent resistance to attack as the security glazing it is designed to hold in place.Any method used to hold framed or unframed security glazing in place should be of sufficient strength to resist dislodgement by any anticipated means of manual attack.NOTE Glazing resistant to
33、 attack by firearms might not necessarily be resistant to manual attack.Where security glazing is installed within 1 m of a personnel workstation, the danger of spalling from the glazing material should be considered.4.2 Framed security glazingThe frame should be of sufficient strength and stiffness
34、 to hold the glazing securely in place when either the frame or the glazing is subjected to the specified level of attack. The depth of the rebate should be sufficient that, after allowance for edge clearance around the glazing, there is adequate edge cover to prevent the glazing being levered out o
35、f the frame when subjected to the specified level of attack. NOTE The depth required depends on the strength and stiffness of the rebate upstand and the glazing bead.The bead should be fixed, preferably on the private side, in a manner which ensures that it cannot be removed or dislodged when subjec
36、ted to the specified level of attack.Glazing gaskets and sealants should be checked for compatibility with the security glazing. Where possible, chemically curing sealants with good adhesion to the glazing and the framing material should be used.4.3 Fixing methods for explosion resistant glazing4.3.
37、1 Fixings where the glass is intended to remain unbrokenWhere the glass is intended to remain unbroken (except for any sacrificial layer), the support system should be designed so that it resists the forces of the explosion transmitted through the glass, i.e. the full blast overpressure, without sig
38、nificant distortion, maintaining the glass in position. NOTE 1 The fixing method for this design is usually of a much heavier duty than those used to resist wind forces. This is particularly important with conventional glazing frames, where the frames themselves, the attachment of the frame to the b
39、uilding, and the attachment of beads to the frame, might need to be considerably stronger than normal.The installation of such glazing also has consequences for the building structure, since the full force of the blast is transmitted to the structure, which should be designed to resist it. NOTE 2 Th
40、is might only be practical for new buildings. BS 5357:20074 BSI 20074.3.2 Fixings where the glass is allowed to fractureWhere the glass is allowed to fracture, glazing with deep rebates on all edges of the glass is recommended. The beads holding the glass in place should be of sufficient strength to
41、 remain intact and hold the glass in position.NOTE If the glass is allowed to fracture, the forces transferred to the frame and the structure is reduced and might result in a practical economical option.It is recommended that a tested framing system and proven fixing method is adopted but, in genera
42、l, increasing the edge cover to the glass and bolting the bead at frequent intervals is sufficient.4.4 Unframed bullet-resistant security glazingUnframed bullet-resistant security glazing should have no gaps, except as described in 5.4, between the edges. Butt joints should not be used for bullet-re
43、sistant glazing.Note Guidance edge finishes of laminated glass can be found in BS EN ISO 12543-5 and defects on edges that will not be framed in BS EN ISO 12543-6.4.5 SupportsAll fixings to ceilings, walls, floors and junctions should be of sufficient strength to securely hold in place all component
44、s of the installation, when subjected to the specified level of attack.Vertical supports (mullions) should be securely fixed at ceiling and floor levels.Alternatively, if a counter is provided and it is strong enough to provide satisfactory anchorage, fixings may be made at the counter level rather
45、than at floor level. Vertical supports should generally be taken through suspended ceilings and raised floors in order to achieve satisfactory anchorage.Horizontal supports (transoms) should be securely fixed at each junction with the vertical supports and walls where appropriate.Where a counter or
46、other non-glazed component is provided as part of the glazed security screen, it should be securely supported and fixed to the walls and floors.5 Complete installations5.1 GeneralProtection against the specified level of attack, whether by security glazing or other material, should extend to a minim
47、um of 2 m above the floor level on the public side. Above a height of 2 m, protection should be of a kind that can prevent an attacker climbing or vaulting the screen, or throwing objects over the screen, or aiming or firing a firearm directly or indirectly at anyone in the private space, and it sho
48、uld be continued up to the ceiling (or through a suspended ceiling). BSI 2007 5BS 5357:20075.2 Screening materialThe resistance of brickwork, wood, and other building materials, varies considerably. To ensure that the screening material in a complete installation (for example, in counter screens and
49、 fronts) provides at least as good a level of protection as the security glazing, it should be backed by, for example, mild steel at least 6 mm thick or other material offering equivalent protection of security glazing in accordance with BS 5051-1:1988, class G2 or below or class S86. If security glazing of BS 5051-1:1988, class R1 or R2 is used in the installation, the screening material should be backed by, for example, at least 8.5 mm thick armour steel or a sufficient thickness of
