Foreword
ISO (the International Organization for Standardization, is a worldwide
federation of national standards bodies (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, 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.
The main task of ISO technical committees is to prepare International
Standards. In exceptional circumstances a technical committee may
propose the publication of a Technical Report of one of the following types:
type 1, when the required support cannot be obtained for the
publication of an International Standard, despite repeated efforts;
type 2, when the subject is still under technical development or where
for any other reason there is the future but not immediate possibility of
an agreement on an International Standard;
type 3, 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).
Technical Reports of types 1 and 2 are subject to review within three years
of publication, to decide whether they can be transformed into International
Standards. Technical Reports of type 3 do not necessarily have to be
reviewed until the data they provide are considered to be no longer valid or
useful.
Amendment 1 to ISO/TR 11071-1, which is a Technical Report of type 3,
was prepared by Technical Committee ISO/TC 178, Lifts, escalators,
passenger conveyors, Working Group 4.
ISO/TR 11071 consists of the following parts, under the general title
Comparison of worldwide lift safety standards:
Part 1: 1990, Electric lifts (elevators)
Part 2: 1996, Hydraulic lifts (elevators)
NOTE It is intended that an amendment 1 to Part 2 will provide similar
references to Japanese and Australian standards.

Introduction
Technical report ISO/TR 11071-1:1990 consists of a comparison of the
requirements of lifts (elevators) as covered by the following safety
standards for electric lifts that were used in various countries or regions at
the end of 1989:
a) CEN - European Standard EN 81: Part 1, Lifts and service lifts [Edition
1985 - as presented in BS 5655-1:1986 (excluding national Appendix)];
b) ASME - ASME/ANSI A17.1
Safety code for elevators and escalators
(Edition 1987 including the A17.1a-1988 and A17.1b-1989 addenda);
c) CSA - CSA Standard CAN3-B44 Safety code for elevators (Edition
1985, including Supplement 1-1987);
d) USSR - USSR Elevator design and safe operation code (Edition
NEDRA, 1971 as presented in English version NEDRA 1972);
e) CMEA - Elevator safety regulations of the Council for Mutual Economic
Assistance.
The intention of the Technical Report was to provide reference information
to assist national committees when reviewing and revising individual
standards. This process was expected to initiate a gradual convergence of
the technical requirements.
The original Technical Report did not include the safety requirements and
standards used in Japan.
At the initiative of Technical Committee ISO/TC 178, experts from the
Japanese Elevator Association provided ISO/TC 178 Working Group 4 with
comprehensive reports on the Japanese safety standards system and with
tables comparing their requirements with those in the five listed safety
standards. It should be noted that since the publication of ISO/TR 11071-1,
the CMEA has been put out of use and USSR [NEDRA, 1971] standard
withdrawn and replaced with a new code for the Russian Federation
[PUBEL:1992]. Furthermore, the ASME and CSA standards have been
revised and new editions published.
By Resolution No. 1995/117; however, ISO/TC 178 asked WG 4 to review
the material prepared by Japanese experts with the intention of publishing
it as an amendment to ISO/TR 11071-1:1990, rather than revising and
updating the whole 1990 edition.
This amendment does not replace compared safety standards from the
1990 edition. The information contained in this Technical Report does not
necessarily represent the opinions of the standards-writing organizations
responsible for the development of the safety standards being compared,
and they should be consulted regarding interpretations of their
requirements.
NOTE ISO/TR 11071-1 and this amendment do not deal with lift rated loads and
suspension ropes. The subjects are, however, covered in ISO/TR 11071-2,
published in 1996, in clauses 7 and 8, which include tables and analysis of
corresponding requirements in CEN, ASME and CSA standards as related to both
electric and hydraulic lifts (elevators).

Comparison of worldwide lift safety standards —
Part 1:
Electric lifts (elevators)
AMENDMENT 1: References to Japanese standards
This amendment illustrates Japanese lift safety requirements in relation to the requirements of all standards covered
in the original Technical Report, ISO/TR 11071-1:1990.
This amendment consists of the following:
a) reproduction of the original 1990 tables, with the addition of the Japanese requirements in new columns in
tables 3.3.2.3, 3.9.2 and 3.10.2 of clause 3;
b) additions to the previous annex A, reproducing the original 1990 tables but incorporating a new column
«JAPAN»;
c) addition of a new annex D containing information on the Japanese safety standards system with regard to lifts.
These tables may therefore be inserted to replace the original tables in ISO/TR 11071-1:1990.
This amendment does not constitute a general review of ISO/TR 11071-1:1990.

The following lift safety requirements are not covered in the tables, but specific Japanese requirements exist.
(a) Earthquake requirements
A seismic sensor is required to be set up in the machine room to control the operation of elevators. When an
earthquake occurs, the car should be stopped at the nearest floor. Item 129 Article 7 of the Building Standard Law
Enforcement Order provides that the following should be considered according to structural earthquake-proof
standards:
— the stress and deflection in the equipment and the material of each elevator part caused by earthquakes
should be within the allowable stress of the material and fixed tolerances of the equipment (e.g. strength of
guide rail and rail bracket);
— elevator equipment should be securely fixed so as to not, be moved, fall down, or be damaged by
earthquakes (e.g., derailment-restraint of counterweight and earthquake-proof fixings of machine room
equipment);
— traction sheaves should be so constructed as to keep ropes in place in the case of earthquakes (e.g.,
provision of deep-grooved sheaves and installation of retaining guards for ropes);
— travelling cables should be guarded from damage by projections in hoistway during the earthquake.
(b) Fire emergency elevators
Fire emergency elevators are required to be installed in buildings exceeding 31 m in height, according to Item 2 of
Article 34 of the Building Standards Law of Japan.
Regulations prescribe the details for fire emergency elevators, such as necessary units, location in the building,
structure of hoistway, machine room, elevator hall, and the operation.
