適用范圍：This European Standard specifies the minimum level of resistibility of equipment havingtelecommunication port(s) to overvoltages and overcurrents.This European Standard covers telecommunication equipment installed at customer premises asshown 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 electrifiedrailway),– 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 equipmentmanufacturers.This European Standard applies to equipment having telecommunication port(s) connected to externalconductors, 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.
