Gives principles of test procedures to evaluate the thermal endurance of electrical insulating materials and simple combinations of such materials; describes the conditions to be observed during the various tests and shows the basic analysis methods to derive the temperature index, the relative temperature index and the halving interval from the test results. Attention is given to test data which do not completely satisfy the requirements of linearity and dispersion of the thermal endurance relationship.
