Seven types of commercially available distribution composite insulators with sheds made of EPR or epoxy resin have been subjected to various functional aging tests recommended by the IEC or the IEEE. The influence of UV radiation on the aging of the shed materials was also evaluated. The usefulness of the various aging and diagnostic tests is discussed and a modification of the recommended test procedures is proposed in order to improve the evaluation of the long term performance of these insulators.
