EN 81-2:1998+A3:2009 and EN 81-2:1998 will have a transition period of eighteen months in which they wil
6、l co-exist. It is intended that this period will allow manufacturers time to develop new products to meet the requirements contained in the A3 amendment. Based on this transition period, BS EN 81-2:1998 will be withdrawn in May, 2011. Following the implementation of the Lift Directive on 1 July 1999
7、, BS 5655-2:1988, together with BS 5655-12:1989, will apply only for modernization of existing lift installations.

29、t EU Directives ; - elimination of obvious errors ; - incorporation of proposals resulting from interpretation requests dealing with the improvement relative to the progress in technology ; - improvement of the references to other standards according to the progress in that field. After the CEN Enqu
30、iry on prEN81-2:1994 the EU Directive on Lifts (95/16/EC) was adopted. The requirements resulting from the essential health and safety requirements of this Directive being not taken into consideration in the draft have been summarised in the Addendum prA1:1996 to prEN81-2:1994 and submitted to the m
31、embers of CEN/TC 10 for approval. Having received the approval this Addendum has been incorporated into this standard taking into account the comments received from TC members. This standard does not correspond in all points to the present internal rules of CEN regarding the format of safety standar
32、ds. However, the format of this standard has been accepted by the interested parties and is therefore regarded as the better way of implementation of the essential health and safety requirements than a formalistic re-draft. This mainly because of the coming into force of the EU Directive 95/16/EC on
33、 97-07-01. BS EN 81-2:1998+A3:2009EN 81-2:1998+A3:2009 (E) 6 With the next revision of the standard, being already intended, this shortcomings will be removed. %Amendment 3 is needed on one hand because of the revision of the machinery directive, amendment of the lifts directive, and on the other ha
34、nd because of improvements in the state of the art. New ESRs in the revised machinery directive give new requirements for the fixation of protective guards. The amendment is addressing these new requirements. Furthermore the borderline between the scope of the machinery directive and the lifts direc
35、tive has changed. As a result of this the scope of EN 81-2 (and EN 81-1) is revised by means of this amendment. Additionally this amendment is giving more severe requirements for (1) measures against the risk of stumbling during loading and unloading, and for (2) measures against the risks due to un
36、controlled movements. These requirements are not linked to the revision of the machinery directive, but are a result of improved state of the art. By means of this amendment, an improved conformity to the relevant ESRs in the Lifts Directive and Machinery Directive is achieved. b) crushing ; c) fall
37、ing ; d) impact ; e) trapping ; f) fire ; g) electric shock ; h) failure of material due to : 1) mechanical damage ; 2) wear ; 3) corrosion. 0.1.2.2 Persons to be safeguarded : a) users ; b) maintenance and inspection personnel ; c) persons outside the lift well, the machine room and pulley room (if
38、 any). 1)Within CEN/TC 10 an interpretation committee has been established to answer questions about the spirit in which the experts have drafted the various clauses of this standard. The issued interpretations are available from National Standards Bodies. BS EN 81-2:1998+A3:2009EN 81-2:1998+A3:2009
39、 (E) 8 0.1.2.3 Objects to be safeguarded : a) loads in car ; b) components of the lift installation ; c) building in which the lift is installed. 0.2 Principles In drawing up this standard the following have been used. 0.2.1 This standard does not repeat all the general technical rules applicable to
40、 every electrical, mechanical, or building construction including the protection of building elements against fire. 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 utilizatio
41、n the requirements may be more stringent than elsewhere. 0.2.2 This standard does not only address the essential safety requirements of the Lift Directive, but additionally states minimum rules for the installation of lifts into buildings/constructions. There may be in some countries regulations for
42、 the construction of buildings etc. which cannot be ignored. Typical clauses affected by this are those defining minimum values for the height of the machine and pulley rooms and for their access doors dimensions. 0.2.3 When the weight, size and/or shape of components prevent them from being moved b
43、y hand, they are : a) either fitted with attachments for lifting gear, or b) designed so that they can be fitted with such attachments (e.g. by means of threaded holes), or c) shaped in such a way that standard lifting gear can easily be attached. 0.2.4 As far as possible the standard sets out only
44、the requirements that materials and equipment have to meet in the interests of safe operation of lifts. 0.2.5 Negotiations have been made between the customer and the supplier about : a) the intended use of the lift ; b) environmental conditions ; c) civil engineering problems ; d) other aspects rel
45、ated to the place of installation. ! 0.2.6 Risk analysis, terminology and technical solutions have been considered taking into account the methods of the EN 61508-series of standards. This led to a necessary classification of safety functions applied to PESSRAL.“ BS EN 81-2:1998+A3:2009EN 81-2:1998+
46、A3:2009 (E) 9 0.3 Assumptions Possible risks have been considered of each component that may be incorporated in a complete lift installation. Rules have been drawn up accordingly. 0.3.1 Components are : a) designed in accordance with usual engineering practice and calculation codes, taking into acco
47、unt all failure modes ; b) of sound mechanical and electrical construction ; c) made of materials with adequate strength and of suitable quality ; d) be free of defects. Harmful materials, such as asbestos are not used. 0.3.2 Components are kept in good repair and working order, so that the required
48、 dimensions remain fulfilled despite wear. 0.3.3 Components will be selected and installed so that foreseeable environmental influences and special working conditions do not affect the safe operation of the lift. 0.3.4 By design of the load bearing elements, a safe operation of the lift is assured for loads ranging from 0 % to 100 % of the rated load. 0.3.5 !The requirements of this European Standard regarding electrical safety devices are such that the possibility of a failure of an electric safety device (see 14.1.2.1.1
