9、 Inside back coverBS5655-2:1988 ii BSI 05-2000 National foreword This revision of BS 5655-2, which supersedes the 1983 edition, has been prepared under the direction of the Mechanical Handling Standards Committee and is identical with European Standard EN 81-2:1987. It is the second Part of a Britis

10、h Standard relating to lifts and service lifts, which supersedes portions of relevant Parts of BS 2655, the relevant obsolescent requirements being retained for reference purposes and to enable existing lift installations to be maintained. The standard comprises the following Parts. Part 1: Safety r

11、ules for the construction and installation of electric lifts (implementing EN 81-1), together with PD6500 “Explanatory supplement to BS 5655-1”; Part 2: Safety rules for the construction and installation of hydraulic lifts; (implementing EN 81-2) Part 3: Electric service lifts 1) ; Part 4: 2) Part 5

12、: Specification for dimensions of standard lift arrangements; (implementing ISO 4190-1 and ISO 4190-3) Part 6: Code of practice for selection and installation; Part 7: Specification for manual control devices, indicators and additional fittings; (implementing ISO 4190-5) Part 8: Specification for ey

13、ebolts for lift suspension; Part 9: Specification for guide rails; (implementing ISO 7465) Part 10: Specification for testing and inspection of electric and hydraulic lifts; Part 11: Recommendations for the installation of new and the modernization of electric lifts in existing buildings 1) ; Part 1

14、2: Recommendations for the installation of new and the modernization of hydraulic lifts in existing buildings 1) ; Part 13: Code of practice for vandal resistant lifts 1) . Further Parts are anticipated. Subclause 0.1.4 of the general introduction to EN81 (see the explanatory note at the end of this

15、 national foreword) permits each country to append to the European Standard certain amendments that are necessary to comply with current national legislation or codes of practice; the UnitedKingdom national variations for Part2 of EN81 are given in National appendix V. 1) In preparation. 2) Reserved

16、 for future publications.BS5655-2:1988 BSI 05-2000 iii Prior to 30 June 1989 all new and replacement hydraulic lifts may comply with the requirements of either this standard or those of BS 5655-2:1983. The requirements of this standard only are applicable to all new installations which are tendered

17、for after30June1989, unless it can be shown that owing to space limitations, compliance is not reasonably practicable. Special provisions are permissible to meet certain site conditions often present in buildings that have been in use for many years. It is intended that the use of new equipment shou

18、ld not automatically be restricted because certain site conditions are now more rigorous than formerly. However, any deviations from this standard will have to ensure a minimum acceptable standard of safety having regard to the circumstances affecting the installation, whilst permitting an installat

19、ion of reasonable standard to be modernized or reconstructed, in stages if necessary (seeBS 5655-12 3) ). EXPLANATORY NOTE ON THE ARRANGEMENT OF EN 81-2. EN 81-2 contains the “General introduction” and the “Scope and field of application” for EN81 as a whole; these are followed by a contents list fo

20、r Part2 and then the text of Part2 (beginning with the “Introduction” to Part 2 and followed by the “Scope and field of application” for Part2). A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct app

21、lication. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i to iv, theENtitle page, pages 2 to 90, an inside back cover and a back cover. This standard has been updated

39、h the operation of lifts and service lifts 4) . 0.1 In drawing up this standard the following methods have been adopted. 0.1.1 An analysis of the risks has been carried out for each component that may be incorporated in a complete lift or service lift installation. Rules have been drawn up according

40、ly. 0.1.2 This standard, specially associated with lifts and service lifts, does not repeat all the general technical rules applicable to every electrical, mechanical or building construction, or to environmental protection. It is of course assumed that all components shall: 0.1.2.1 be correctly des

41、igned, be of sound mechanical and electrical construction, be made of materials with adequate strength and of suitable quality and be free of defects; 0.1.2.2 be kept in good repair and working order. It will in particular be ensured that the dimensional requirements remain fulfilled despite wear. 0

42、.1.3 This special standard for lifts and service lifts does not give rules relating to the protection against fire of building elements. However, as these rules have a direct influence on the choice of landing doors and on the specification and design of electrical control systems, it is necessary t

43、o refer to them. 0.1.3.1 The choice of the landing doors which depends on the required behaviour in fire, is dealt with in 7.2.2. The most common structural arrangements have been shown with the corresponding types of door designated by F and S. However, if statutory requirements lay down for certai

44、n arrangements type F instead of type S, the National Committees may make the necessary amendment. 0.1.3.2 The electrical control systems recommended for each example of structural arrangement given are described in Appendix G. 0.1.4 This special standard for lifts and service lifts cannot ignore ce

45、rtain specifications which do not belong intrinsically to the field of these appliances or which are not the cause of barriers to trade, but which have an effect on the safety of users or servicing personnel and the upkeep of the installation. In certain countries these specifications come within th

46、e legislative field or accepted Codes of Practice. The National Committees may, therefore, make one or more of the following amendments to the specifications of the standard which refer to this clause: a) delete the marked text; b) provide additional clauses (for example, definitions, clauses concer

47、ned, frequency of inspections, . . .); c) replace the value indicated by a value providing greater safety. NOTE 1Reference to this clause appears in the body of the standard in the form (N.a, b or c). The clauses concerned are indicated in the margin by the sign P. NOTE 2These amendments shall form

48、the subject, in each country, of a national appendix. 0.2 It has, however, seemed necessary to establish certain requirements of good construction, either because they are peculiar to lift manufacture or because in the case of lift utilization the requirements may be more stringent than elsewhere. 0

49、.3 As far as possible the standard sets out only the requirements that materials and equipment have to meet in the interests of lift safety. 0.4 When mention is made of a design for the sake of clarity, this should not be considered to be the only possible design; any other solution leading to the same result can be applied if it is equivalent in operation and at least equally safe. 0.5 A study has been made of the various accidents possible with lifts in the following areas. 0.5.1 Types of possi
