IEC 61587-6:2021 pdf download – Mechanical structures for electrical and electronic equipment – Tests for IEC 60917 and IEC 60297 series – Part 6: Security aspects for indoor cabinets.
1 Scope This part of IEC 61587 specifies security aspects and security performance levels of the mechanical construction of indoor cabinets in accordance with IEC 60917 (all parts) and IEC 60297 (all parts). This document does not address vandalism. NOTE Protection against vandalism is typically controlled by user-specific requirements. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

3 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • • IEC Electropedia: available at http://www.electropedia.org/ ISO Online browsing platform: available at http://www.iso.org/obp 3.1 handle <cabinet> mechanical component to open or close the door of a cabinet, equipped on the door of the cabinet
3.2 key <cabinet> device to allow only authorized access to a cabinet, assembled into the handle of the cabinet or on the door of the cabinet 3.3 mechanical lock <cabinet> mechanical component assembled in the door of a cabinet that secures the door to the frame or other structural member of the cabinet and is operated by the handle 3.4 multipoint mechanical lock <cabinet> system of more than one mechanical lock operated by a single handle 3.5 access security level <cabinet> level of security against unauthorized access, determined by the security measures needed to obtain access to the cabinet Note 1 to entry: The access security level of an indoor cabinet depends on the type of installation site (building) and on the cabinet’s location in the building. 3.6 access protection <cabinet> protection against unauthorized access to a cabinet 3.7 security performance <cabinet> performance of the mechanical components of a cabinet to achieve the intended protection against unauthorized access Note 1 to entry: The mechanical components of the cabinet are shown in Figure 1.
4 Security aspects for indoor cabinets General 4.1 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.
