scope:
Applies to post insulators and post insulator units of ceram ic material or glass intended for indoor or outdoor service, and to post insulators of organic material intended for ind oor service in electrial installations or equipment operatin g on alternating current systems with a nominal voltage grea ter than 1000 V and a frequency not greater than 100 Hz. It may also be regarded as a provisional standard for insulator s for use on direct current systems. The insulators covered by this stan--------
