It extends the scope of the tests which were included in the 1958 edition of the
standard, and the types of certificate now included require that assurances of
satisfactory performance from certain aspects be given together 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 Authority 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 safety 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
obsolescent concurrently with the publication of BS 5655 “Lifts and service lifts”
Part 1:1979 “Safety rules for the construction and installation of electric lifts”,
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1) This standard is no longer applicable to all new lifts installed in such new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 BS 5655-1 (31 May 1979).
2) All new lifts ordered after 31 May 1979, for installation in such buildings as
have not yet been commenced but for which final plans existed
before 31 May 1979, should be constructed preferably in accordance with
BS 5655-1 or, if space considerations make it necessary, in accordance with
this standard. If, however, such lift installations are scheduled for
commissioning after 31 May 1984, the requirements of BS 5655-1 only are
applicable.
3) All new lifts ordered after 31 May 1979, 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
BS 5655-1. If, however, such lift installations are scheduled for commissioning
after 31 May 1984, the requirements of BS 5655-1 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
commissioned before 31 May 1984, for use in existing buildings that were built
before 31 May 1979, are permitted to be in accordance with either this
standard or BS 5655-1. After 31 May 1984, the requirements of BS 5655-1 only
are applicable 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 should not
automatically be restricted because certain site conditions are now more
rigorous than formerly.
Appendix F of BS 2655-7:1970 will, however, continue to be applicable to the
future maintenance and inspection of existing electric lift installations
constructed in accordance with BS 2655.
Appendix A and Appendix F. Appendix A and Appendix F of this Part of this
standard should be endorsed:
This appendix is rendered obsolescent under the conditions stated in the foreword
(See Amendment No. 2).
A British Standard does not purport to include all the necessary provisions of a
contract. Users of British Standards are responsible for their correct application.

The Factories Act 1961 and the Offices, Shops and Railway Premises (Hoists and Lifts)
Regulations 1968, provide that every hoist or lift shall be thoroughly examined by a competent
person:
1) In the case of a continuous hoist or lift or a hoist or lift not connected with mechanical power —
at least once in every period of 12 months.
2) In the case of other hoists or lifts — at least once in every period of 6 months.
A report of the result of every such examination is required in a prescribed form. (Form F54.)
In premises where the Factories Act applies, the prescribed form must be attached to the general
register. Otherwise it must be kept available for inspection for a period of 2 years.
When the examination shows that the hoist or lift cannot be used with safety unless certain repairs
are carried out immediately or within a specified time a copy of the report must be sent to the
appropriate enforcing authority, i.e. the District Inspector of Factories, the District Inspector of
Mines and Quarries or the local authority, within 28 days of the completion of the examination.
