FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60297-5-100 has been prepared by subcommittee 48D: Mechanical
structures for electronic equipment, of IEC technical committee 48: Electromechanical com-
ponents and mechanical structures for electronic equipment.
The text of this standard is based on the following documents:
FDIS Report on voting
48D/238/FDIS 48D/247/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

INTRODUCTION
This part of IEC 60297 is based on IEC 60297-1 (1986), IEC 60297-3 (1984), its Amendment 1

(1992), and IEC 60297-4 (1995). Contained in this design overview are references to related

detail standards which ensure dimensional interchangeability of subracks and plug-in units

requiring plug-in unit injector/extractors, electromagnetic shielding provision, electrostatic

discharge (ESD) protection, keying, a multi-purpose alignment pin and subrack rear mounted

plug-in units. The dimensional relationship of IEC 60297-3 and IEC 60297-4 is based upon the

IEC 60603-2 connector series
This standard, in whole or in part, applies only to the mechanical structures for electronic
equipment practices according to the IEC 60297 series.

MECHANICAL STRUCTURES FOR ELECTRONIC EQUIPMENT –

DIMENSIONS OF MECHANICAL STRUCTURES

OF THE 482,6 mm (19 in) SERIES –

Part 5-100: Subracks and associated plug-in units –

Design overview
1 Scope and object
This part of IEC 60297 covers extended features added to subracks and compatible printed
boards and plug-in units according to IEC 60297-3 and IEC 60297-4. By implementing these
extended features to the subracks and plug-in units, a new subrack and plug-in unit
(incompatible with IEC 60297-3 and IEC 60297-4) type is created.
The purpose of this standard is to give a design overview of the related detail standards which
will ensure dimensional interchangeability of subracks and associated plug-in units. The
extended features contained in this standard may be referred to and/or implemented
independently. For mechanical and climatic tests, refer to IEC 61587-1. For electromagnetic
shielding performance tests refer to IEC/TS 61587-3.
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this part of IEC 60297. For dated references, subsequent amendments
to, or revisions of, any of these publications do not apply. However, parties to agreements
based on this part of IEC 60297 are encouraged to investigate the possibility of applying the
most recent editions of the normative documents indicated below. For undated references, the
latest edition of the normative document referred to applies. Members of IEC and ISO maintain
