10、ntrolled Copy, (c) BSI BS 5655-13:1995 ii BSI 01-1999 Foreword This Part of BS 5655 has been prepared by Technical Committee MHE/4. It is the thirteenth Part of a British Standard relating to lifts and service lifts. It is intended to provide guidance to purchasers and manufacturers of lifts which a
11、re to be installed in public buildings and public areas such as local authority housing, shopping precincts and multi-storey car parks, and which are liable to attack by vandals. This standard recommends certain additional features that could, with advantage, be selected for incorporation into a lif
12、t installation over and above those specified by BS 5655-1 or BS 5655-2. BS 5655 comprises the following Parts. Part 1: Safety rules for the construction and installation of electric lifts (implementing EN 81-1), together with PD 6500 “Explanatory supplement to BS 5655-1”; Part 2: Safety rules for t
13、he construction and installation of hydraulic lifts (implementing EN 81-2); Part 3: Specification for electric service lifts; Part 4: (reserved for future publication); Part 5: Specification for dimensions of standard lift arrangements (implementing ISO 4190-1 and ISO 4190-2); Part 6: Code of practi
14、ce for selection and installation; Part 7: Specification for manual control devices, indicators and additional fittings (implementing ISO 4190-5); Part 8: Specification for eyebolts for lift suspension; Part 9: Specification for guide rails (implementing ISO 7465); Part 10: Specification for the tes
15、ting and inspection of electric and hydraulic lifts; Part 11: Recommendations for the installation of new, and the modernization of, electric lifts in existing buildings; Part 12: Recommendations for the installation of new, and the modernization of, hydraulic lifts in existing buildings; Part 13: R
16、ecommendations for vandal resistant lifts; Part 14: Specification for hand-powered service lifts and platform hoists1). This British Standard has been converted from DD 197:1990 Recommendations for vandal resistant lifts, which is now withdrawn. It is presented in the form of recommendations support
17、ed by commentaries intended to provide useful insight into the reasoning behind the recommendations. This British Standard takes the form of guidance and recommendations. It should not be quoted if it were a specification and particular care should be taken to ensure that claims of compliance are no
18、t misleading. Reference should also be made to the provisions for safe working recommended in BS 7255 Code of practice for safe working on lifts, which is recommended to all those who have duties under the Health and Safety at Work etc. Act, 1974 1 and other health and safety legislation. 1) In prep

22、GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 5655-13:1995 BSI 01-19991 1 Scope This Part of BS 5655 supplements BS 5655-1 and BS 5655-2 with additional recommendations and performance criteria intended to increase the vandal resistance of lifts. It does not cover such measures as improved building
23、security, enhanced aesthetics, etc. which might also be usefully considered. It is assumed that car and landing doors are operated automatically with characteristics taken from Tables 1 to 4 of BS 5655-5:1989. NOTEA totally enclosed well, and car and landing doors which are operated automatically, a
24、re prerequisites to vandal resistance. This British Standard assumes that the more restrictive access is to equipment, the less likely will be the occurrence of vandalism. 2 References 2.1 Normative references This Part of BS 5655 incorporates, by dated or undated reference, provisions from other pu
25、blications. These normative references are made at the appropriate places in the text and the cited publications are listed on the inside back cover. For dated references, only the edition cited applies; any subsequent amendments to or revisions of the cited publication apply to this Part of BS 5655
26、 only when incorporated in the reference by amendment or revision. For undated references, the latest edition of the cited publication applies, together with any amendments. 2.2 Informative references This Part of BS 5655 refers to other publications that provide information or guidance. Editions of
27、 these publications current at the time of issue of this standard are listed on the inside back cover, but reference should be made to the latest editions. 3 Definitions For the purposes of this Part of BS 5655, the definitions given in BS 5655-1:1986 and BS 5655-2:1988 apply. 4 Machine room 4.1 Con
28、struction Machine rooms should be windowless and of sound construction with walls of either not less than 225 mm nominal solid brick thickness, or other material that will provide equivalent strength. COMMENTARY Windows are not intrinsically secure (evidence exists of access being gained through the
29、 breaking of machine room windows). Windows are not needed for lighting purposes as there is a requirement in BS 5655-1 and BS 5655-2 for adequate artificial lighting. Windows are not needed for ventilation as other requirements for ventilation are given in BS 5655-1 and BS 5655-2. (See also 4.2.) T
30、he recommendation for walls of not less than 225 mm nominal solid brick thickness can only be substantiated by virtue of historical evidence, however this recommendation has been made to avoid the use of materials that will not provide adequate strength. 4.2 Ventilation Ventilation openings should p
31、referably be inaccessible from the outside. Where ventilation openings are accessible from the outside they should be louvred or provided with an equivalent means of protection. Any louvre should be not greater than 250 mm 250 mm, of sufficient strength to withstand a force of 2 500 N applied over a
32、n area of 100 cm2 of round or square shape and provided with baffles which prevent a rod of any section passing through any aperture. COMMENTARY Since ventilation openings are essential and a requirement of BS 5655-1 and BS 5655-2, recommendations for the strength and the design criteria have been g
33、iven. 4.3 Access 4.3.1 Machine room doors and trap doors should be of solid construction, preferably smooth and flush fitting, without rebates and should have a surface spread of flame not inferior to class 2 of BS 476-7:1987. It is essential that the machine room doors close automatically. COMMENTA
34、RY It is considered that rebates at machine room doors and trap doors might permit the insertion of an implement for the purposes of effecting an unauthorized entry. 4.3.2 The doors and their locks should be sufficiently robust to resist forced entry. They should be self-locking, capable of being op
35、ened from the inside without a key and should conform to BS 3621:1980. COMMENTARY Self locking doors are recommended to avoid doors being inadvertently left open thereby allowing unauthorized access.

37、ey: a) resist that force without permanent deformation and without elastic deformation greater than 5 mm; and b) operate satisfactorily after such a test. NOTESee commentary to 6.1. COMMENTARY It is considered that the machine room door has a strength equal to that of a lift landing door (see commen
38、tary to 6.1). It is considered that in view of the recommendations made in 4.1 to 4.3, additional special provisions, such as the locking of controllers, are not necessary in the machine room. 4.4 Warning notices The warning notices on the outside of the machine room should be of durable and non-fla
39、mmable material and permanently fixed in such a manner as to resist removal. 5 Well ventilation Ventilation openings should preferably be inaccessible from outside the lift well but, if they are accessible, they should be constructed as recommended in 4.2. 6 Landing door construction GENERAL COMMENT
40、ARY In recognition of the fact that lift landing entrances are prone to vandalism, with abuse occurring to the doors, door sliding equipment, locks, operator and linkages, clause 6 deals with improving the mechanical strength of equipment and making vulnerable equipment less accessible. A view exist
41、s that vandalism is more prevalent in areas which are unobserved. Consideration has, therefore, been given toward the provision of full or partial see-through doors. However, if see-through doors are provided, it is important that the correct glass/plastics is used and securely fixed. The use of sin
42、gle panel sliding doors is preferred as the problems associated with interference to door linkages are thereby eliminated. Nevertheless in some circumstances the use of multi-panel doors, glass doors and vision panels would need to be considered (see also commentary to 6.3). 6.1 Doors, with their lo
43、cks, should possess mechanical strength such that in the locked position when a force of 2 500 N is applied at right angles to the panel at any point on either face, evenly distributed over an area of 100 cm2 of round or square shape, they: a) resist that force without permanent deformation and with
44、out elastic deformation greater than 5 mm; and b) operate satisfactorily after such a test. COMMENTARY The recommendation for 2 500 N has been adopted from CSA-B44-M90 2, recognizing that a risk of damage to landing doors exists from people colliding with the doors at a certain speed. In arriving at
45、 this figure, the Canadian Standards Association (CSA) made tests using a mass consisting of an elastic envelope containing sand or water to reproduce, as far as possible, the mass and consistency of human bodies. A mass of 200 kg was selected to represent the bodies of two men running in the corrid
46、or and hitting the door. The mass was hung like a pendulum, and impacted against the door at a speed of 2.78 m/s, corresponding to a moderate running speed of 10 km/h. After much testing and analysis, the conclusion was reached that the panels, hangers, guides and guide shoes ought to be capable of
47、withstanding the force of 2 500 N applied on the landing side at right angles to, and approximately at, the centre of the panel. 6.2 The top and bottom of horizontal sliding doors should be provided with a means for retaining the door panel in position, should the roller or guide shoe assemblies fai
48、l. Displacement of the door panel at the top and bottom should not exceed 20 mm when the door panel is subjected to a force, from the landing side only, of 5 000 N applied at right angles over an area of 900 cm2 of round or square shape and at the approximate centre of the panel. COMMENTARY The valu
49、es of 5 000 N and 900 cm2 are again derived from CSA-B44-M90 and equate to the force produced by a person(s) kicking the landing doors. 6.3 Where panels are mechanically linked, the linkage should, where practicable, be inaccessible during normal operation.
