IEC 61952 Ed. 1.0 b:2002

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.
