15、es (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations
16、, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the IS
17、O/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the
18、member bodies casting a vote. In exceptional circumstances, when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example), it may decide by a simple majority vote of its participating members to
19、publish a Technical Report. A Technical Report is entirely informative in nature and does not have to be reviewed until the data it provides are considered to be no longer valid or useful. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent r
20、ights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/TR 11071-1 was prepared by Technical Committee ISO/TC 178, Lifts, escalators and moving walks. This second edition cancels and replaces the first edition (ISO/TR 11071-1:1990), which has been updated. It also
21、 incorporates the Amendments ISO/TR 11071-1:1990/Amd.1:1999, References to Japanese standards, and ISO/TR 11071-1:1990/Amd.2:2001, References to Australian standards. ISO/TR 11071 consists of the following parts, under the general title Comparison of worldwide lift safety standards: Part 1: Electric
22、 lifts (elevators) Part 2: Hydraulic lifts (elevators) ISO/TR 11071-1:2004(E) vi ISO 2004 All rights reservedIntroduction to the first edition (1990) At the 1981 plenary meeting of ISO/TC 178, work began on a comparison of CEN standard EN 81-1 with the American, Canadian, and USSR safety codes. In 1
23、983, Working Group 4 was officially formed to carry out the task of preparing a cross reference between the relevant sections of these standards and to analyze the differences on selected subjects. The goal at that time was to prepare a technical report which would provide reference information to a
24、ssist national committees when reviewing and revising individual standards which may initiate gradual convergence of the technical requirements. In 1984, the study was expanded to include the CMEA safety standard. The content of this report is based on the information provided by the WG 4 members. T
25、he information which could not be obtained on the CMEA standard at the time of publication is noted in the report by a “?” in some of the tables. This report is intended to aid standards writers in developing their safety requirements, and to help standards users understand the basis for the require
26、ments as they are applied throughout the world. This report is not intended to replace existing safety standards. Conclusions are arrived at in some cases, but only where there is unanimity amongst the various experts. In other cases, the reasons for the divergent views are expressed. This report mu
27、st be read in conjunction with the various safety standards, as it was often necessary to summarize the requirements for the sake of clarifying the comparisons. Further, the information contained in this report does not necessarily represent the opinions of the standards writing organizations respon
28、sible for the development of the safety standards which are being compared, and they should be consulted regarding interpretations of their requirements (see Annex B). Introduction to this edition Since the original publication of this Technical Report in 1990, each standard compared therein has bee
29、n revised or amended. The recommendations in the form of “agreed upon points” stated in the original report have also affected the revisions of the national standards. Furthermore, since 1990 two amendments to the original report have been published: Amendment 1: References to Japanese standards (19
30、99-04-15); and Amendment 2: References to Australian standards (2001-07-15). The original report and amendments have been widely used by the lift industry and standards writing organizations, including ISO/TC 178. Users have expressed the need for an updated and consolidated version of the document,
31、 in particular the comparison tabulations. In response, with Resolution 208/2002, ISO/TC 178 requested WG4 “to update comparison tables in ISO/TR 11071 with data from the most recent published standards for lifts, and to republish both documents, Part 1 and Part 2, with updated tables and with minim
32、um changes to the narrative sections”. The narrative sections of the original publication, in particular the assumptions, historical background, observations and suggestions as well as the points agreed upon, were the result of extensive work by ISO/TC 178 Working group 4. ISO/TC 178 is currently wo
33、rking on a new series of ISO documents under the general title “Safety requirements for lifts (elevators)”. In that process, the updated comparison tables are being used as a reference. Extensive work on a complete re-write of the narrative sections is not deemed necessary. However, republication of
34、 the text with only minor editorial changes would help readers to understand the background to the safety concerns being addressed in the current national standards for lifts. To clarify the scope of the revisions to the narrative sections or clauses, and to minimize inconsistencies between the data
35、 in the tables and in the narrative parts, “NOTES” have been inserted. TECHNICAL REPORT ISO/TR 11071-1:2004(E) ISO 2004 All rights reserved 1Comparison of worldwide lift safety standards Part 1: Electric lifts (elevators) 1 Scope This Technical Report consists of a comparison of the requirements of
36、selected topics as covered by the following worldwide safety standards (excluding regional or national deviations): a) CEN European Standard EN 81-1:1998, Safety rules for the construction and installation of lifts Part 1: Electric lifts; b) ASME A17.1-2000 and CSA B44-00, Safety Code for elevators
37、and escalators; c) Building Standard Law of Japan Enforcement order Section 2, Elevator equipment, Articles 129-3 to 129-13, as well as year 2000 Ministry of Construction notices: Nos. 1413 up to and including 1418; Nos. 1423, 1424, 1428 and 1429; No. 1597; d) AS1735.1-2001, Lifts, escalators and mo
38、ving walks Part 1: General requirements, and AS1735.2-2001, Lifts, escalators and moving walks Part 2: Passenger and goods lifts Electric. NOTE 1 The following standards were compared in the original (1990) publication: CEN EN 81 Part 1:1985; ASME/ANSI A17.1 (1987 edition plus the A17.a-1988 and A17
39、.1b-1989 addenda); CSA/CAN3-B44 (1985 edition plus Supplement 1 1987); USSR Elevator design and safe operation code (Edition NEDRA, 1971); CMEA Elevator Safety Regulations of the Council for Mutual Economic Assistance. NOTE 2 Since the 1990 edition: the ASME and CSA standards have been harmonized wi
40、th insignificant deviations, therefore shown in a single tabulation column; the USSR and CMEA standards have been withdrawn following the political change to the former Soviet Union and East Block; in Russia, the PUBEL document has been issued, which is currently undergoing major revisions; therefor
41、e, all related references to USSR and CEMA have been removed in this edition and no new data for the Russian Federation have been introduced. ISO/TR 11071-1:2004(E) 2 ISO 2004 All rights reservedThis report applies to electric traction lifts only, although some sections may also be applicable to pos
42、itive drive lifts suspended by rope or chain. It should be noted that, in addition to the standards listed above, lifts must conform to the requirements of other standards covering mechanical, structural and electrical equipment. 2 Terminology NOTE In this section and throughout the document, except
43、 the Annexes, the acronyms listed below have the meaning given: CEN EN 81-1:1998; ASME A17.1b1989; CSA B44 Supplement 1 1997; AS AS1735 Part 1 JAPAN One of standards listed in 1c). 2.1 Lifts and elevators 2.1.1 The term lift as used in the CEN standard is referred to as elevator in ASME and CSA stan
