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.

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.
IEC 60297-3-101 defines the interfaces of the basic 482,6 mm (19 in) subrack and associated
plug-in units.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (CEI) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a
pour objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les
domaines de l'électricité et de l'électronique. A cet effet, la CEI – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de la CEI"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec la CEI, participent
également aux travaux. La CEI collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),
selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de la CEI
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de la CEI se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de la CEI. Tous les efforts raisonnables sont entrepris afin que la CEI
s'assure de l'exactitude du contenu technique de ses publications; la CEI ne peut pas être tenue responsable
de l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de la CEI s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de la CEI dans leurs publications
nationales et régionales. Toutes divergences entre toutes Publications de la CEI et toutes publications
nationales ou régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) La CEI elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de la CEI. La CEI n'est responsable d'aucun des services effectués par les organismes de
certification indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à la CEI, à ses administrateurs, employés, auxiliaires ou
mandataires, y compris ses experts particuliers et les membres de ses comités d'études et des Comités
nationaux de la CEI, pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre
dommage de quelque nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais
de justice) et les dépenses découlant de la publication ou de l'utilisation de cette Publication de la CEI ou de
toute autre Publication de la CEI, ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L’attention est attirée sur le fait que certains des éléments de la présente Publication de la CEI peuvent faire
l’objet de droits de brevet. La CEI ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits
de brevets et de ne pas avoir signalé leur existence.
