This standard applies to composite suspension/tension insulators consisting of a load-bearing cylindrical insulating solid core consisting of fibres - usually glass - in a resin-based matrix, a housing (outside the insulating core) made of polymeric material and end fittings permanently attached to the insulating core.
Composite insulators covered by this standard are intended for use as suspension/tension line insulators.
This standard can be applied in part to hybrid composite insulators where the core is made of a homogeneous material (porcelain, resin).
