Anotation

IEC 60216-1:2025 specifies the general ageing conditions and procedures to be used for deriving thermal endurance characteristics and gives guidance in using the detailed instructions and guidelines in the other parts of IEC 60216. Although originally developed for use with electrical insulating materials and simple combinations of such materials, the procedures are considered to be of more general applicability and are widely used in the assessment of materials not intended for use as electrical insulation. In the application of this document, 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 this document, no transition, in particular no first-order transition, is expected to occur in the temperature range under study. This edition includes the following significant technical changes with respect to the previous edition: a) the definition for temperature index (TI) has been updated; b) requirements for selection of related materials used, e.g. in different colours (5.1.2), have been added; c) test procedure for thickness sensitivity (5.5 et 6.6) has been added; d) Annex C "Concepts in earlier editions" has been deleted. LIEC 60216-1:2025 specifie les conditions generales de vieillissement et les methodes a utiliser pour en extraire les caracteristiques dendurance thermique, et donne des recommandations pour lutilisation des instructions detaillees et des lignes directrices dans les autres parties de lIEC 60216. Meme si a lorigine elles ont ete developpees pour etre utilisees sur les materiaux isolants electriques et des combinaisons simples de tels materiaux, ces methodes sont considerees comme etant applicables plus generalement et sont largement utilisees pour verifier des materiaux non destines a etre utilises comme isolants electriques. Dans lapplication du present document, il est estime quune relation pratiquement lineaire existe entre le logarithme du temps exige pour provoquer la modification predeterminee de la propriete, et linverse de la temperature absolue correspondante (relation dArrhenius). Pour que le present document soit valable, il est prevu quil ny ait pas de transition, en particulier de transition du premier ordre, dans la plage de temperatures a letude. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - la definition de lindice de temperature (IT) a ete mise a jour; - des exigences pour le choix des materiaux connexes utilises, par exemple, en differentes couleurs (5.1.2), ont ete ajoutees; - des methodes dessai pour la sensibilite a lepaisseur (5.5 et 6.6) ont ete ajoutees; - lAnnexe C "Concepts existant dans les editions precedentes" a ete supprimee.
