DIN IEC/TS 61244-2:2016-05

This part of Technical Specification IEC/TS 61244 describes procedures for predicting the aging of polymeric materials at low dose rates. Three procedures are presented which can be used to extrapolate data obtained from high dose rate experiments to the low dose rates typical of service conditions. These methods assume that homogeneous oxidation has been achieved under the test conditions. The techniques described in the following clauses are methods which have been found to be useful for a range of elastomeric, thermoplastic and thermoset materials. The procedures require a considerable number of test data to enable predictions to be made under low dose rate conditions. The responsible committee is DKE/K 183 "Bewertung und Qualifizierung von elektronischen Isolierstoffen und Isoliersystemen" ("Evaluation and qualification of electrical insulating materials and systems ") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
