DIN EN 60216-8:2014-01

This part of IEC 60216 specifies the general ageing conditions and simplified procedures to be used for deriving thermal endurance characteristics. These procedures specify the principles for evaluating the thermal endurance properties of materials exposed to elevated temperature for long periods. In the application of this standard, it is assumed that a practically linear relationship exists between the logarithm of the time required to cause the predetermined property change and the reciprocal of the corresponding absolute temperature (Arrhenius relationship). For the valid application of the standard, no transition, in particular no first-order transition should occur in the temperature range under study. Throughout the rest of this standard the designation "insulating materials" is always taken to mean "insulating materials and simple combinations of such materials". 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.
