This British Standard, prepared under the authority o

16、f the Mechanical Engineering Industry Standards Committee, is a revision of and supersedes the1958 edition, which was entitled “Electric lifts”. The new title reflects the extension of the scope of this British Standard. Amendments to Parts2 and 3 of this standard have been published, and implement

17、the change in title. The revised Part1 and additional new parts are being published separately and, together with Parts2 and 3, are as follows: Part 1: General requirements for electric, hydraulic and hand-powered lifts. This Part is basically a revision of the1958 edition of BS2655-1, without the b

18、uilding requirements and list of definitions, and extended to cover the engineering and safety requirements for new hydraulic and hand-powered lifts as well as for new electric lifts. Part 2: Single speed polyphase induction motors for driving lifts. This Part covers the type of electric motor speci

19、ally designed for driving lifts. It should be used in conjunction with BS2613 1)and gives additional requirements including the class of lift rating and special limits of temperature rise. Part 3: Arrangements of standard electric lifts. This part gives standard dimensions for lift wells and machine

20、 rooms in relation to life capacity and platform sizes, for seven classes of lifts. Part 4: General requirements for escalators and passenger conveyors. This Part specifies engineering and safety requirements for escalators and passenger conveyors. The latter may be described as machines in which th

21、e passenger carrying surface remains parallel to the direction of motion and are uninterrupted. Part 5: General requirements for paternosters. This Part specifies engineering and safety requirements for paternosters which may be described as machines where series of cars are continuously running in

22、closed loops, and are characterized by the car floors remaining substantially horizontal when the direction of motion is reversed at the extremities of car travel. Part 6: Building construction requirements. This Part specifies structural and fire resistance requirements for the equipment covered by

23、 Parts1, 4 and 5. Part 7: Testing and inspection. This Part specifies tests, examination and certification of new and modified equipment covered by Parts1, 4 and 5. Part 8: Modernization or reconstruction of lifts. This Part specifies engineering and safety requirements. Part 9: Definitions. This Pa

24、rt gives definitions of terms used in the remainder of the standard. Part 10: General requirements for guarding. This part specifies requirements for the guarding of moving parts and protection against hazards from electrical equipment. It relates to equipment covered in Parts1, 4 and 5. CP 407:1972

25、, British Standard Code of Practice for electric, hydraulic and hand-powered lifts. The code gives general information and guidance for planning, purchasing, installation and maintenance of passenger, goods and service lifts. In case of difficulty in classifying any equipment in accordance with the

26、headings of Parts1, 4 and 5, reference should be made to the relevant definitions in Part9. This part of the standard covers examination and certification of new seeAmendment No.2(May1979) and modified equipment covered by Parts1, 4 and 5. It is principally concerned with safety. 1) BS2613, “The ele

27、ctrical performance of rotating electrical machinery”.BS2655-7:1970 BSI 09-1999 iii It extends the scope of the tests which were included in the1958 edition of the standard, and the types of certificate now included require that assurances of satisfactory performance from certain aspects be given to

28、gether with certain contract and performance data. The certificates also require that the equipment to which they relate shall comply with all the relevant requirements of the standard. However, an “Exemption” clause is included for non-compliance where this is acceptable to the Certification Author

29、ity and other affected parties, such as the user. It is envisaged that a Central Certification Authority might be set up, but in the interim the authority for signing the certificate will be one acceptable to the parties concerned (such as the manufacturer, user, insurance company and appropriate sa

30、fety authority). In many cases this will in practice be a representative of the manufacturer. Appendix A and Appendix F of this Part of this standard are rendered obsolescentconcurrently with the publication of BS5655 “Lifts and service lifts” Part 1:1979 “Safety rules for the construction and insta

31、llation of electriclifts”, under the conditions stated below. 1) This standard is no longer applicable to all new lifts installed in such new buildings as are designed after the date of publication of BS5655-1(31May1979). 2) All new lifts ordered after31 May1979, for installation in such buildings a

32、s have not yet been commenced but for which final plans existed before31 May1979, should be constructed preferably in accordance with BS5655-1 or, if space considerations make it necessary, in accordance with this standard. If, however, such lift installations are scheduled for commissioning after31

33、 May1984, the requirements of BS5655-1 only are applicable. 3) All new lifts ordered after31 May1979, for installation in such new buildings as were under construction or completed before that date, are permitted to be constructed in accordance with either this standard or BS5655-1. If, however, suc

34、h lift installations are scheduled for commissioning after31 May1984, the requirements of BS5655-1 only are applicable unless it can be shown that, owing to space limitations, compliance is not reasonably practicable. 4) Such new replacement lifts and major modifications to existing lifts as are com

35、missioned before31 May1984, for use in existing buildings that were built before31 May1979, are permitted to be in accordance with either this standard or BS5655-1. After31 May1984, the requirements of BS5655-1 only are applicable unless it can be shown that, owing to space limitations, compliance i

36、s 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 should not automatically be restricted because certain site conditions are now more rigorous

37、than formerly. Appendix F of BS2655-7:1970 will, however, continue to be applicable to the future maintenance and inspection of existing electric lift installations constructed in accordance with BS2655. Appendix A and Appendix F. Appendix A and Appendix F of this Part of this standard should be end

38、orsed: This appendix is rendered obsolescent under the conditions stated in the foreword (See Amendment No. 2).BS2655-7:1970 iv BSI 09-1999 A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct applicat

39、ion. 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, pagesi toiv, pages1to27 and a back cover. This standard has been updated (see copyright date) and may have had amendments
