Abstract
Comparative test results are presented on polyesterimide coated copper wires, a polyester glass mat laminate and a heterocyclic epoxy resin. Tests have been performed according to the application principles of the EAP theory, described in Paper II of this series. Results of tests show that the ageing behavior of these materials is well predictable on the basis of EAP tests, and in every case better than the prediction based on conventional test results, whenever a reliable comparison could be made. With the exception of one insignificant deviation, all the materials behaved according to the EAP principles developed in the theoretical Paper II of this series. The results described here and those published earlier can be taken as the proof of reliability of the EAP method for the thermal endurance testing of electrical insulating materials.
