FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
The “Dimensions of mechanical structures of the 482,6 mm (19 in) standards are defined in
IEC 60297. To the original IEC 60297-3:1988 publication was added Amendment 1:1995. The
additional requirements were published in IEC 60297-4:1995 with Amendment 1:1999.
The extended requirements were published in the IEC 60297-5-1XX series (2001).
Responding to market requirements and for more clarity it became necessary to merge and
technically enhance these standard “parts” into 3 “new” standards for subracks and
associated plug-in units. This “merged” standard series now defined as IEC 60297-3-101,
IEC 60297-3-102 and IEC 60297-3-103 explains its relationship to the previous “fragmented”
IEC 60297-X standards, see Figure 1.
The nomenclature of these new standards has been revised. The relationship to IEC 60297-1
(Part 1: Panels and Racks) has been maintained. The relationship to IEC 60297-2 (Part 2:
Cabinets and pitches of rack structures) has been maintained. The relationship to IEC 61587-1
(Part 1: Climatic, mechanical tests and safety aspects for cabinets, racks, subracks and
chassis) and IEC TS 61587-3 (Part 3: Electromagnetic shielding performance tests for
cabinets, racks and subracks) has been added.
The IEC 60297-3-101 standard defines the interfaces of the basic 482,6 mm (19 in) subrack
and associated plug-in units.
