This International Standard is applicable to polymeric insulators whose insulating body
consists of one or various organic materials. Polymeric insulators covered by this standard
include both solid core and hollow insulators. They are intended for use on HV overhead lines
and in indoor and outdoor equipment.
The object of this standard is
– to define the common terms used for polymeric insulators;
– to prescribe common test methods for design tests on polymeric insulators;
– to prescribe acceptance or failure criteria, if applicable;
These tests, criteria and recommendations are intended to ensure a satisfactory life-time
under normal operating and environmental conditions (see Clause 5). This standard shall only
be applied in conjunction with the relevant product standard.
