Electrical insulating materials - Thermal endurance properties - Part 8: Instructions for calculating thermal endurance characteristics using simplified procedures

IEC 60216-8:2013 specifies the general ageing conditions and simplified procedures to be used for deriving thermal endurance characteristics, which are shown by temperature index (TI) and/or relative temperature index (RTI) and the halving interval (HIC). The 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.

Matériaux isolants électriques - Propriétés d'endurance thermique - Partie 8: Instructions pour le calcul des caractéristiques d'endurance thermique en utilisant des procédures simplifiées

La CEI 60216-8:2013 spécifie les conditions de vieillissement générales et les procédures simplifiées à utiliser pour déduire les caractéristiques d'endurance thermique, qui sont représentées par l'indice de température (IT) et/ou l'indice de température relatif (RTI) et l'intervalle de division par deux (IDC). Les procédures spécifient les principes régissant l'évaluation des propriétés d'endurance thermique des matériaux exposés à une température élevée pendant de longues périodes. Dans le cadre de l'application de la présente norme, on considère qu'il existe une relation pratiquement linéaire entre le logarithme du temps nécessaire pour provoquer le changement de propriété prédéterminé et l'inverse de la température absolue correspondante (relation d'Arrhenius). Pour que l'application de la présente norme soit valide, il convient qu'aucune transition, en particulier aucune transition du premier ordre, ne se produise dans la plage de températures à l'étude.

Elektroizolacijski materiali - Lastnosti toplotne vzdržljivosti - 8. del: Navodila za izračunavanje karakteristik toplotne vzdržljivosti z uporabo poenostavljenih postopkov

Ta del standarda IEC 60216 določa splošne pogoje staranja in poenostavljene postopke, ki naj se uporabijo za izpeljavo lastnosti toplotne vzdržljivosti, ki so prikazane s toplotnim indeksom (TI) in/ali relativnim toplotnim indeksom (RTI) in razpolovnim intervalom (HIC). Postopki določajo načela za vrednotenje lastnostni toplotne vzdržljivosti materialov, ki so dolgo izpostavljeni povišani temperaturi. V uporabi tega standarda se predvideva, da obstaja praktično linearno razmerje med logaritmom časa, potrebnega za povzročitev spremembe vnaprej določene lastnosti, in recipročno glede na ustrezno absolutno temperaturo (Arrheniusovo razmerje). Za veljavno uporabo standarda se v proučevanem temperaturnem obsegu ne sme pojaviti prehod, zlasti pa ne prehod prvega reda. V ostalem delu tega standarda izraz »izolacijski materiali« vedno pomeni »izolacijski materiali in enostavne kombinacije takšnih materialov«.
