Standards Worldwide •
This page provides information on the main standards (and technical rĂŠgulations) in use worldwide.
BT has confirmed that ESE National Standards would remain valid and thus BT recognized there ould e o e ide e of o fli t et ee NF C ‐ a d IEC EN ‐ sta dards a d consequently there is no reason, technical or otherwise, for the withdrawal of the respective national standard.BT has requested that this standard be modified in order to cancel all refere e to the IEC EN ‐ series, allowing the NF C ‐ sta dard to e ist, ith the proposal of possible future migration to international level (lEC). Accordingly, it was established that European ESE standards (France, Spain, Portugal, Slovaquia, etc.) will not conflict with other European standards and will remain valid.
• GIMELEC would draw your attention to the fact that the ter s of refere e of NF C ‐ a d • other standards, addressing alternative terminals (NF C ‐ , PR EN ‐ ‐ ) ere fro the • outset, er differe t. It is a fa t that NF C ‐ , whilst referring to ESE Technology also • comments on other standards for lightning protection systems, particularly incorporating • faraday cage, franklin rod and catenary wire systems. the 'camouflaging' of NF C ‐102 by IEC EN • ‐ and its proponents, that FRENCH STANDARD NF C ‐ is still in full force.
