Applies to composite line post insulators consisting of a load-bearing, cylindrical, insulating solid core made up of fibres - usually glass - in a resin-based matrix, a housing (outside the insulating core) made of elastomer material (e.g. silicone or ethylene-propylene) and end fittings permanently attached to the insulating core.
The object of this standard is to
- define the terms used,
- prescribe test methods,
- prescribe acceptance or failure criteria
This standard does not include requirements dealing with the choice of insulators for specific operating conditions.
