INTRODUCTION
The security of electrical and electronic equipment or systems currently applied in the fields of
ICT (information and communication technology) and of industrial/infrastructure control
systems, is of critical importance. The advent of 5G telecommunication service and edge
computing/edge servers/edge switches places ICT equipment in industrial environments. This
document defines performance levels for cabinets not only for ICT data centre and office
locations but for any combination of equipment, purpose, and location.
In general, security is achieved by restrictions and protections against improper or
unauthorized access from both the hardware and software sides of the systems.
The security of the hardware of electrical and electronic equipment or systems, which are
housed in mechanical structures such as cabinets based on IEC 60297 series and IEC 60917
series, depends:
– on conditions of their installation sites,
– on the system hardware which provides access protection at the installation sites, and
– on the robustness of the mechanical structures and of their mechanical locks both at the
access gates/doors of the installation sites and of the mechanical structures.
Therefore, a classification of the installation conditions and of the levels of security measures
for the hardware is very important for design and practices of various electronic equipment or
systems, which are used in the field of ICT, industrial control, transportation and others.
From this point of view, this document intends to clarify the relationship between the
installation conditions and the security requirements for indoor cabinets, and to provide the
required performance and test methods on mechanical components related with security
provisions for indoor cabinets which are in accordance with the IEC 60297 series and
IEC 60917 series.
Vandalism protection is typically controlled by user-specific requirements. Therefore, this
document does not address vandalism.

4 Security aspects for indoor cabinets
4.1 General
Security for electronic equipment should be designed from the point of view of both hardware
and software. With respect to the security of hardware installed in a cabinet, the security
aspects of the cabinet depend on the following factors:
a) access security level of the cabinet installation site (access security within the building);
b) security performance of the cabinet.
The access security within the building, as part of the physical security, is primarily aimed to
be effective against unauthorized forced entry. In this regard, many international or regional
regulations and specifications for building doors, gates, building door handles and key-locking
systems and other building physical security facilities are defined.

The security performance of the cabinet is determined by the choice of specific handle, key,
mechanical lock and other components, which are different from the hardware for buildings
and are mostly dedicated to cabinets for electrical and electronic systems.
Designers and users should consider those points properly to establish security aspects for
the intended use of the relevant indoor cabinet.
4.2 Access security level of the cabinet
In the case of the indoor cabinet, the access security level depends on building level
restrictions to reach the cabinet installation sites. Figure 2 and Table 1 show typical access
security levels in buildings or premises.
Security performance for the intended use cabinet should be appropriate for the access
security levels shown in Table 1. End users should use Table 1 to describe their installation
location to cabinet providers.

5 Security performance levels of cabinets
5.1 General
Table 2 shows security performance levels of cabinets and related security performance
levels of mechanical components.
Application of security performance levels of cabinets should be defined by the required
security measures of the cabinet-mounted electronic system and the access security levels of
the installation sites. Nevertheless, whatever the access security level of the installation site,
the security level of the cabinet may be chosen independently with reference to requirements
arising from the intended electronic system. Designers and users should study and clarify the
actual conditions of the installation site and the required security measures of the intended
electronic system, and apply the optimum security performance levels for cabinets.

5.2.2 Tests for strength of mechanical locks and hinges
Figure 3 shows the test method for assessing the strength of the mechanical locks and of the
door hinges. Loads are applied from the inside of the cabinet door in the direction indicated.
For further details on testing the strength of the handle as a stand-alone component see
Annex A (normative).
a) Handle, flat lever type b) Handle, lever type c) Handle, T-bar type

Figure 3 – Static loading test for mechanical lock and hinges
Criteria: After applying the static load (200 N or 400 N) 3 times, there shall be no deformation
of any of the components of the handle, mechanical lock, hinges, door, or cabinet that affect
form, fit, or function.
For multipoint mechanical locks each mechanical lock in the system is tested independently.

– 12 – IEC 61587-6:2021 © IEC 2021
Figure 3 shows the tests for typical handles and mechanical locks. When using different type
handles and mechanical locks designers and users should modify the test method above
according to the function of the specific handle or mechanical lock design.
5.2.3 Tests for operation of handle and mechanical lock
Table 4 indicates procedures for the tests of operation of handle and mechanical lock.

The test cycle shall be repeated 10 000 times. The test cycle shall be repeated 10 000 times.
1) Start with the door closed and handle locked 1) Start with the door closed and handle locked
2) Unlock the handle 2) Unlock the handle
3) Pull-up the handle lever 3) Turn the handle lever or T-bar to the position that
allows the door to be opened
4) Turn the handle lever to the position that allows
the door to be opened 4) Return the handle lever or T-bar to the initial
position
5) Return the handle lever to the initial position
5) Lock the handle
6) Lock the handle
Criteria: After the test, there shall be no deformation of any of the components of the handle,
mechanical lock, or key that affect form, fit, or function.
Table 4 indicates the test procedures for typical handles. Different types of handles may
require a different procedure for unlock, door open, door close, and/or lock operation. In such
cases, the cycle test procedures should be modified according to the specific door operation.
5.2.4 Tests for panel strength
Loads are intended to be applied from inside the cabinet in the direction indicated in Figure 4.
If this is not practical then the panels may be modified to provide means to apply the loads
from the outside of the cabinet. The modification could be carried out by welding a pull tab or
stud to the panel or by drilling a hole and pulling on a bolt, tab, or stud positioned through the
hole. In any case the area loaded by the pulling device shall not exceed 100 mm . The
method of loading the panels shall be reported.

Figure 4 – Static loading test for panel strength
Criteria: After applying the static load (100 N or 200 N) 3 times, there shall be no deformation
of the panels or cabinet that affect form, fit, or function.
5.3 Key
Table 5 shows security performance levels for keys.
The "key codes" shown in Table 5 are key security numbers or key security values typically
used for cabinet doors according to IEC 60917 (all parts) and IEC 60297 (all parts), and
represent the number of key codes that are distinct enough to prevent closely matched key
codes from operating the same lock. Key pad entry is considered limited security as access
can be compromised by observation of the person gaining access to the cabinet. RFID or
magnetic card entry is considered medium security as cards can be compromised by the
possession of a stolen or copied card. Any form of biometric reader is considered high
security as it requires the presence of an authorized person for entry.

Partie 6: Aspects liés à la sécurité des baies intérieures

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation composée
de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l'IEC). L’IEC 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, l'IEC – 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 l'IEC"). 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 l'IEC, participent également aux
travaux. L’IEC 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 l'IEC concernant les questions techniques représentent, dans la mesure du
possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l'IEC intéressés
sont représentés dans chaque comité d’études.
3) Les Publications de l'IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l'IEC. Tous les efforts raisonnables sont entrepris afin que l'IEC
s'assure de l'exactitude du contenu technique de ses publications; l'IEC 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 l'IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l'IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l'IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L'IEC 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 l’IEC. L'IEC 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 l'IEC, 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 l'IEC,
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 l'IEC ou de toute autre Publication de l'IEC,
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 l'IEC peuvent faire l'objet
de droits de brevet. L'IEC ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits de brevets
et averti de leur existence.
