1.1 Scope
This Standard applies to suspension and dead-end composite insulators used on ac overhead transmission lines with a nominal voltage 69 kV or greater and a frequency not greater than 100 Hz.
1.2 Objectives
The objectives of this Standard are to
(a) define the terms used;
(b) define insulator characteristics (mechanical, electrical, and dimensional) and prescribe the conditions under which the specified values of these characteristics shall be verified;
(c) specify test methods; and
(d) specify acceptance criteria.
