Defines test methods for glass, glass-ceramic and ceramic materials for electrical insulation purposes. Designed to provide test results typical of the material from which the test pieces are processed. In the majority of cases, ceramic components for insulating purposes are of a different shape and size to test pieces. The results of tests only provide a guide to the actual properties of components, and the limitations imposed by the method of processing and forming are discussed where relevant.
