Title Application of equipotential bonding and earthing in buildings with information technology equipment
Project Number 16443
Abstract/Scope 1.1 This European Standard applies to the equipotential bonding inside buildings in which information technology equipment is going to be installed. It contributes to the standardisation of information technology equipment and co-ordinates with the pre-requirements of the generic installation conditions as outlined in IEC 60364-5-548 to achieve the following targets: a) safety from electrical hazards; b) reliable signal reference within the entire information technology installation; c) satisfactory electromagnetic performance of the entire information technology installation. 1.2 A defined bonding configuration down to the equipment level – independent of the equipment supplier – is intended to facilitate – the installation, operation and maintenance of information technology installations in buildings; – the interworking between different information technology equipment (interconnected by metallic links). The specification of information technology equipment and of the pre-requirements of installation are subject to agreement of the parties (e. g. the equipment supplier and the purchaser or building owner). 1.3 This standard applies to buildings with information technology equpiment or in which the installation of information technology equipment is intended. It provides additional information for architects of buildings and for designers and installers of electrical installations of buildings on some installation concepts that limit electromagnetic influences. Basic considerations are given here to mitigate such influences that may result in disturbance. This standard does not apply to buildings which may be subject to a harsh electromagnetic environment, or rooms containing the generation, transmission or termination of voltages over AC 1000 V. This standard does not address the specific requirements for telecommunication centres; these are specified in EN 300253.

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
