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 and 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. This standard shall only be applied in conjunction with the relevant product standard.
