Includes a comparison of the requirements of selected topics as covered by worldwide safety standards (excluding regional or national deviations).

This Technical Report consists of a comparison of the requirements of selected topics as covered by the following worldwide safety standards (excluding regional or national deviations): CEN— European Standard EN81-1:1998, Safety rules for the construction and installation of lifts— Part1: Electric lifts; ASME A17.1-2000 and CSA B44-00, Safety Code for elevators and escalators; Building Standard Law of Japan— Enforcement order — Section2, Elevator equipment, Articles129-3 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; AS1735.1-2001, Lifts, escalators and moving walks - Part1: General requirements, and AS1735.2-2001, Lifts, escalators and moving walks - Part2: Passenger and goods lifts - Electric. NOTE1 The following standards were compared in the original (1990) publication: CEN EN81 - Part1:1985; ASME/ANSI A17.1 (1987 edition plus the A17.a-1988 and A17.1b-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. NOTE2 Since the 1990 edition: the ASME and CSA standards have been harmonized with insignificant deviations, therefore shown in a single tabulation column; the USSR and CMEA standards have been withdrawn following the political change to the former Soviet Union and East Block; in Russia, the PUBEL document has been issued, which is currently undergoing major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; therefore, all related references to USSR and CEMA have been removed in this edition and no new data for the Russian Federation have been introduced. This report applies to electric traction lifts only, although some sections may also be applicable to positive 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.
