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 60297-5-107 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:

INTRODUCTION
This part of IEC 60297 is based on IEC 60297-3 (1984), its Amendment 1 (1992), and IEC

60297-4 (1995). It contains detail dimensions which ensure dimensional interchangeability of

subracks with front mounted plug-in units per IEC 60297-4 requiring additional rear mounted

plug-in units as defined in this standard. Front and/or rear subrack mounted plug-in units are

mechanically identical (not electrically), however, the rear subrack mounted plug-in unit is

mounted in a mirror image position to the front subrack mounted plug-in unit. The component

side 1 (printed board reference plane) of the front mounted plug-in unit and the component side
1 of the rear mounted plug-in unit (printed board reference plane) are thus “in line”. The first

front mounted plug-in unit refers to the first printed board position on the left side of the

subrack, viewed from the front. The first rear mounted plug-in unit refers to the first rear

mounted plug-in unit position on the right side of the subrack, viewed from the rear.
Like many of the IEC 60297-3 and IEC 60297-4 subracks and associated plug-in unit basic
dimensions, this standard also refers to the IEC 60603-2 connector series for its basic
dimensional relationship.
This standard 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 5-107: Subracks and associated plug-in units –

Rear mounted plug-in units
1 Scope and object
This part of IEC 60297 covers extended features of subrack rear mounted plug-in units added
to (front mounted) plug-in units and subracks according to IEC 60297-3 and IEC 60297-4. By
implementing this extended feature to the subrack and plug-in units, a new subrack and plug-in
unit type (incompatible with IEC 60297-3 and IEC 60297-4) is created.
The purpose of this standard is to specify dimensions which will ensure dimensional
interchangeability of subracks and associated plug-in units using the extended function of rear
subrack mounted plug-in units added to IEC 60297-3 and IEC 60297-4.
For mechanical and climatic tests refer to IEC 61587-1.
For electromagnetic shielding performance tests refer to IEC/TS 61587-3.
