11、iIt supersedes BS 5655-12:1989, which is withdrawn.This edition is a full revision of the standard. It introduces editorial and technical changes to bring the standard up-to-date, and takes into account the publication of BS EN 81-2:1998 and other publications in the BS EN 81 series up to October 20
12、05.This part of BS 5655 makes reference to the requirements specified in other relevant standards.Attention is drawn to BS EN 81-80. This provides guidance on the progressive improvement to the safety of existing lifts. BS EN 81-80 is the recognized European standard, which represents the considered
13、 thinking of a number of European experts, and it has been approved by all the standards institutions (including BSI). It also contains a checklist to enable verification of the current safety level of the installation being considered.Where a like-for-like replacement of a safety component (see 3.2
14、) is not possible, attention is drawn to the legal requirement for any replacement component to have CE marking applied to it. A safety component is defined by the Lifts Regulations 1997 1.Attention is also drawn to BS 5655-6. Its scope is limited to the installation of new lifts, but its recommenda
15、tions may be used as guidance when making modifications to existing lift installations.Attention is drawn to the legal requirement to ensure that when alterations are made to a lift installed after 1 July 1999, the lift continues to conform to the level of safety defined by the Essential Health and
16、Safety Requirements (EHSRs) of the Lift Regulations 1997.It is important to note any revisions and amendments to BS EN 81-1:1998, for example the Corrigenda dated March 2000 and any published interpretations in DD CEN/TS 81-29.Attention is drawn to BS 7255, which indicates the environment for safe w
17、orking on lifts. BS 7255:2001, Annex B offers suggested improvements for consideration by an owner to improve safe working.Notes and commentaries are provided throughout the text of this standard. Notes give references and additional information that are important but do not form part of the recomme
18、ndations. Commentaries give background information.Attention is drawn to the regulations listed in Annex A. This part of BS 5655 is recommended for use alongside these regulations.Users of this British Standard are reminded that as a code of practice it recommends actions to be taken by all persons
19、involved with lifts: it does not specify requirements for the lifts themselves.As a code of practice, this British Standard takes the form of guidance and recommendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of compliance ar
20、e not misleading.It has been assumed in the drafting of this British Standard that the execution of its provisions will be entrusted to appropriately qualified and competent people.This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its
21、correct application.Compliance with a British Standard does not of itself confer immunity from legal obligations.Summary of pagesThis document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 32, an inside back cover and a back cover.The BSI copyright notice displayed in th
22、is document indicates when the ForewordThis British Standard has been prepared by Technical Committee MHE/4. BSI 30 December 2005document was last issued.BS 5655-12:2005IntroductionIn the UK there are over 200 000 passenger and passenger/goods lifts in service about 50 % of which were installed befo
23、re 1979 and the probability is that these often fail to meet modern safety requirements and standards (see Figure 1).The most important reason for modifications is to enable owners to continue to fulfil their duty to provide for the safe operation of their lift installation(s). Additional reasons fo
24、r modifications of a lift can be to: change the use of a lift, which might result from a change in use of the building; improve reliability; update technologically; improve traffic handling; improve ride quality; reduce energy consumption; improve the aesthetics.These types of modification are often
25、 termed “modernization”.A lift is often refurbished to restore it to, at least, “as good as new condition”. Where worn-out equipment and components are simply replaced on a like-for-like basis, this is not considered to be a modification. Some replacements can occur during routine maintenance operat
26、ions, e.g. the replacement of a burnt-out motor. The status quo of the installation is unchanged and the same level of safety is maintained.The formulation of a lift upgrading scheme should be undertaken by a person competent to do so in conjunction with the client in order to ensure the clients nee
27、ds are fully met. The consequences of a change can depend on a number of factors and each project should be subject to individual risk assessment to identify any issues that should be addressed.The competent person has a duty to carry out a site-specific risk assessment of the works to be undertaken
28、, in accordance with the Management of Health and Safety at Work Regulations (MHSWA) 2 (see A.2). An owner contemplating the modification of a lift is advised to take professional advice.A lift installed before 1 July 1999, when the Lifts Regulations 1997 came into force, is expected to have been in
29、stalled in accordance with the safety rules for the construction and installation current at the time it was put into service. The standards could have been to the earlier BS 2655 or BS 5655 series, etc. Some lifts might have been altered from, for example, a BS 2655 standard, to a BS 5655 standard
30、over a period of time. There is no compulsion on an owner to bring a lift up to the latest standard; this is voluntary. However, in the event of an incident it is likely that the owners attention will be drawn to the best practice contained in the latest safety standards. This situation can be avoid
31、ed by carrying out a safety audit from time to time and upgrading all lifts to the latest safety standard.

35、and goods passenger lifts, serving defined landing levels, having a car designed for the transportation of persons or persons and goods, suspended by jacks, ropes or chains and moving between guide rails inclined not more than 15 to the vertical.This part of BS 5655 does not cover any of the followi
36、ng types of lift:a) new lifts (see Note 2);b) lifting appliances, such as paternosters, mine lifts, theatrical lifts, appliances with automatic caging, skips, lifts and hoists for building and public works sites, ships hoists, platforms for exploration or drilling at sea, construction and maintenanc
37、e appliances;c) installations where the inclination of the guide rails to the vertical exceeds 15;d) lifts with drives other than hydraulic lifts suspended by jacks, ropes or chains;e) like-for-like replacement of lift components (see 3.2);f) goods only lifts;g) lifts with rated speeds, upwards or d
38、ownwards, greater than 1.0 m/s.NOTE 1 The recommendations in this part of BS 5655 may, however, be used as a basis for modernization or modification of such lifts.NOTE 2 Where a lift falls into one of the following categories, it is deemed to be a new lift as defined in the Lifts Regulations 1997 1
39、and this part of BS 5655 is not applicable: dismantled from an existing site and installed at a new site; installed where no lift previously existed; completely replaced; only retains the guide rails.NOTE 3 In some situations (e.g. potentially explosive atmosphere, extreme climate conditions, vandal
40、ism, transporting dangerous goods, etc.), additional measures might need to be taken to those recommended in this part of BS 5655.2 Normative referencesThe following referenced documents are indispensable for the application of this document.

Under no circumstances should the lift installation be le
48、ss safe after the modifications have been made.BS EN 81-80 gives recommendations for improvements to the safety of existing lifts. It is strongly recommended that an audit be carried out in accordance with BS EN 81-80:2003, Annex B before altering any lift installation in order to assess the existin
49、g level of safety and determine what changes are necessary to bring the level to todays state of the art. BS EN 81-80:2003, Table 1 provides a numbered list of 74 significant hazards and BS EN 81-80:2003, Table B.2 gives recommendations for risk reduction measures. Annex B in the present part of BS 5655 summarizes the 74 significant hazards.The results of this audit are expected to give the owner a clear indication of which items are of most concern
