Abstract :
Representative insulations are thermally aged in pure oxygen and also in a moderately good vacuum. The resulting aging rates are compared with similar specimens aged in air and in nitrogen. A 50% dielectric criterion is used in evaluating deterioration rates. The evaporation component of aging is shown to be minor as compared with the oxidation component, for the materials tested, except for siliconeimpregnated materials.
