Main standards about lightning protection

Aplicaciones Tecnológicas’ products meet the most important international and national standards.

Several standards establish the requirements for lightning and surge protection systems. Below, we summarize the most relevant national and internationally:

 

 

Lightning protection systems

  • EN IEC 62305: European and International standard that establishes if it is necessary and how to install a LPS. It includes a risk assessment and the coordination of surge protection devices.
  • EN IEC 62561: Also an European and International standard, it focuses on lightning protection system components (LPSC)
  • Other important standards:
    • NF C 17-102 (France) and UNE 21186 (Spain): Protection of structures and open areas against lightning using early streamer emission (ESE) air terminals
    • NFPA 780 (US): Standard for the installation of lightning protection systems
    • J-549-ANCE-2005 (Mexico): Protection system against thunderstorms
    • And: RAM 2426 (Argentina); JUS N.B4.810 (Rf Yugoslavia); NP 4426 (Portugal); I-20 (Romania); STN 34 1391 (Slovakia).

Protection against overvoltages

  • IEC EN 61643: European and International standard for low-voltage surge protective devices. It includes tests.
  • EN 50550: Power frequency overvoltage protective device for household and similar applications (POP)
  • Other important standards:
    • UL1449 (US): Transient Voltage Surge Suppressors
    • DIN VDE 0675 (Germany): Surge arresters
    • UTE C 15-443 (France): Protection against overvoltages for low voltage electrical installations
    • NF C 61-740 (France): Surge protectors for low voltage installations.

Preventive protection

  • EN 50536: Protection against lightning-Thunderstorm warning systems is a European standard that establishes if is necessary to install storm detectors, as well as its main characteristics.
