IEC 60297-3-107:2012 defines the interface dimensions between subracks and associated plug-in units using connectors as defined in PICMG-MTCA.0 (Fixed board, see Figure 7) and IEC 61076-4-116 (Two part, see Figure 12) and other two part connectors, (see Figure 15). For mechanical and climatic tests refer to IEC 61587-1. For electromagnetic shielding performance tests refer to IEC 61587-3.

La CEI 60297-3-107:2012 définit les dimensions d'interface entre des bacs et des blocs enfichables associés à l'aide de connecteurs comme cela est défini dans la spécification PICMG-MTCA.0 (cartes fixes, voir Figure 7) et dans la CEI 61076-4-116 (en deux parties, voir Figure 12) et d'autres connecteurs en deux parties (voir Figure 15).  Pour les essais mécaniques et climatiques, se rapporter à la CEI 61587-1. Pour les essais de performances du blindage électromagnétique, se reporter à la CEI 61587-3.

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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.
International Standard IEC 60297-3-107 has been prepared by subcommittee 48D:

INTRODUCTION
This standard provides for an alternative/smaller form factor of plug-in units as defined in
IEC 60297-3-101.
New technologies requiring smaller plug-in unit form factors used in 19 in equipment practice
are rapidly gaining acceptance.
Recognizing this development it became obvious that a generic interface standard would be
an advantage to the industry.
This standard is based upon and coordinated with the plug-in unit form factor as defined in
AMC.0 and MicroTCA developed by PICMG (PCI Industrial Computers Manufacturer Group).
By making critical interface dimensions available and permitting the use of alternative
connectors to the industry (beyond AMC.0 and MicroTCA) multiple product solutions may
make use of this technology and will increase the overall market acceptance, increase
availability, and reduce cost.
In order to meet the requirements of small form factor plug-in units within the subrack th
