Anotation

Applies to post insulators and post insulator units of ceramic material or glass intended for indoor or outdoor service, and to post insulators of organic material intended for indoor service in electrical installations or equipment operating on alternating current systems with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It may also be regarded as a provisional standard for insulators for use on direct current systems. Sapplique aux supports isolants et elements de supports isolants dinterieur et dexterieur en matiere ceramique ou en verre et aux supports isolants dinterieur en matiere organique destines a lequipement dinstallations ou dappareils electriques fonctionnant en courant alternatif a une tension nominale superieure a 1 000 V et a une frequence au plus egale a 100 Hz. Elle peut aussi etre consideree comme norme provisoire pour les isolateurs utilises sur des reseaux fonctionnant en courant continu.
