Title Resistibility requirements to overvoltages and overcurrents due to lightning for equipment having telecommunication ports
Project Number 14153
Abstract/Scope This European Standard specifies the minimum level of resistibility of equipment having telecommunication port(s) to overvoltages and overcurrents. This European Standard covers telecommunication equipment installed at customer premises as shown in Figure 1. Overvoltages or overcurrents covered by this European Standard are surges due to direct or indirect lightning on the telecommunication line plant. Overvoltages or overcurrent not covered by this European Standard are – short-term induction of alternating voltages from electric power systems (including electrified railway), – earth potential rise due to power faults or load switching, – direct contacts between telecommunication lines and low voltage power lines. This European Standard is intended for use by network (public/private) operators and the equipment manufacturers. This European Standard applies to equipment having telecommunication port(s) connected to external conductors, i.e. conductor located outside the customer’s building. The tests are type tests and, although they are applicable to a complete system, it is recognised that they may be applied to individual items of equipment during development and design work.

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of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
