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 procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

Introduction
This document has been developed as a step towards the convergence of key requirements in the major
world-wide lift codes and also the updating of ISO/TR 11071 (all parts).
ISO/TR 11071 (all parts) represents a comprehensive comparison of the major lift prescriptive safety
standards in use at the time of publication. Since that time, there has been considerable harmonization
and rationalization of various standards with the result that there are currently three major sets of
prescriptive safety requirements in extensive use. These are the CEN EN 81 series of standards, the
ASME A17 series/CSA B44 of standards, and the JIS TS A 0028-1 and the Building Standard Law of
Japan (BSLJ).
The goal of this document is to provide recommendations to assist national committees, when
reviewing and revising individual standards, to initiate convergence towards harmonization of the
technical requirements.
This document expands the list of “agreed-upon points”, with a view to facilitate convergence of key
requirements of the documents identified above.
In order to divide the work into manageable increments and set the priorities, it was deemed
constructive to start with requirements for door locks, buffers, governors, safeties and brakes as the
first step towards the complete lift.
In order to expedite the convergence process, the recommendations have been prioritized to implement
the harmonization of requirements for safety components. The priorities are ranked as follows:
a) Priority 1, where the design of safety components are directly affected;
b) Priority 2, where the design of systems or requirement language only are affected.
NOTE Priority 1 includes items that should be harmonized first as it affects the design of the components
directly. Priority 2 includes items that should be harmonized at a later stage as it affects the system or
language only.
The comparison of requirements in different parts of the world indicated the importance of good
engineering practice in the implementation of standards with regard to safety. It was concluded that
guidance on good engineering practice was necessary and it would be best to provide this guidance
in ISO/TS 22559-2, the scope of which covers this issue. It is important that this document be read in
conjunction with ISO/TS 22559-2.
This document was prepared by the Task Force on Convergence (TFC) and is based on information
and input provided by the code study groups from Europe (EUCSG), North America (NACSG) and Japan
(JPCSG). After in-depth analysis of differences and rationale, the code study groups have agreed and
formulated actions to be implemented in the course of development or revisions of standards in their
respective regions. Completion of those actions will result in harmonization of code requirements for
door locks, buffers, governors, safeties and brakes and will facilitate free circulation of those safety
components around the world.
This document is intended for use by standard writers in order to implement the prescriptive
recommendations when developing or revising standards.
