S 1.66 Compliance with standards for IT cabling
Initiation responsibility: Head of IT
Implementation responsibility: Head of IT
A standard with the title "Generic Cabling Systems" was published in 1995 that described the topology and classification of communication links for the first time with defined properties as well as a uniform interface for connecting terminal devices. These requirements apply not only to cabling used in office buildings, but can also be applied to other areas of application.
Under the responsibility of the European Committee for Electrotechnical Standardization (CENELEC), the standards are monitored, coordinated with the international committees (ISO/IEC), and, if necessary, advanced and refined.
The standards provide users with support in the building planning, cabling design, planning, implementation, and operation phases of communication cable systems.
In addition to EN 50173-1 - Generic cabling systems, General requirements and parts 2 Office premises, 3 Industrial premises, 4 Residential premises, and 5 Data centres, which were available as drafts at the time this document was written, there are other standards used in planning and installing IT cabling.
When translated to the phase model of the IT Grundschutz Catalogues, the standards can be categorised as follows:
Building planning
- EN 50310 - Application of equipotential bonding and earthing in buildings with information technology equipment
- 5.2: Common bonding network (CBN) within a building
- 6.3: AC distribution system and bonding of the protective conductor (TN-S)

Review questions:
- Have the relevant standards such as EN 50310, EN 50173, and EN 50174 been taken into account while planning the building and the IT cabling?
