Applicable to post insulators of organic material for indoor service in electrical installations or equipment operating in air at atmospheric pressure on alternating current with a nominal voltage greater than 1 000 V up, but not including, 300 kV, as defined by range I of IEC 60071-1, and a frequency not greater than 100 Hz. Composite insulators are not covered by this standard. Est applicable aux supports isolants dinterieur en matiere organique destines a lequipement dinstallations ou dappareils electriques fonctionnant dans lair, a la pression atmospherique, en courant alternatif, a une tension nominale superieure a 1000 V jusqua 300 kV non compris et a une frequence au plus egale a 100 Hz comme defini dans la gamme I de la CEI 60071-1. Les isolateurs ne sont pas couverts par la presente norme.
