Electrical insulating materials - Thermal endurance properties - Part 6: Determination of thermal endurance indices (TI and RTE) of an insulating material using the fixed time frame method
Specifies the experimental and calculation procedures for deriving the thermal endurance characteristics, temperature index (TI) and relative thermal endurance index (RTE) of a material using the 'fixed time frame method (FTFM)'. In this protocol, the ageing takes place for a small number of fixed times, using the appropriate number of ageing temperatures throughout each time, the properties of the specimens being measured at the end of the relevant time interval. This differs from the procedure of IEC 60216-1, where ageing is conducted at a small number of fixed temperatures, property measurement taking place after ageing times dependent on the progress of ageing. The diagnostic tests employed in the fixed time frame method are restricted to destructive tests. The method has not as yet been applied to non-destructive or proof test procedures. Both the TI and the RTE determined according to the FTFM protocol are derived from experimental data obtained in accordance with the instructions of IEC 60216-1 and IEC 60216-2 as modified in this standard. The calculation procedures and statistical tests are modified from those of IEC 60216-3 and IEC 60216-5. The significant technical changes with respect to the previous edition are as follows. - This new edition has been supplemented by Annex G and the corresponding software.

Matériaux isolants électriques - Propriétés d'endurance thermique - Partie 6: Détermination des indices d'endurance thermique (TI et RTE) d'un matériau isolant en utilisant la méthode de "trame de durées fixes (fixed time frame)"
La présente partie de la CEI 60216 spécifie les méthodes expérimentales et de calcul à utiliser pour en extraire les caractéristiques d'endurance thermique, l'indice de température (TI) et l'indice d'endurance thermique relatif (RTE) d'un matériau en utilisant la méthode de 'trame de durées fixes (fixed time frame)'. Avec ce protocole, le vieillissement se produit après un petit nombre de durées déterminées, en utilisant le nombre approprié de températures de vieillissement tout au long de chaque durée pertinente, les propriétés des éprouvettes étant mesurées à la fin de chaque intervalle de temps. Cela diffère de la méthode de la CEI 60216-1, dans laquelle le vieillissement est effectué à un petit nombre de températures déterminées, la mesure des propriétés des éprouvettes se produisant après des durées de vieillissement variables en fonction de la progression du vieillissement. Les essais de diagnostic employés dans la méthode de trame de durées fixes sont limités aux essais destructifs. La méthode n'a pas encore été appliquée aux essais non destructifs ni aux procédures d'essais d'épreuves. Les deux indices d'endurance thermique TI et RTE déterminés selon le protocole FTFM (fixed time frame method), sont déduits des données expérimentales obtenues conformément aux instructions de la CEI 60216-1 et de la CEI 60216-2, et conformément aux modifications de la présente norme. Les méthodes de calcul et les essais statistiques sont différents de ceux de la CEI 60216-3 et de la CEI 60216-5. Par rapport à l'édition précédente, les modifications techniques majeures sont les suivantes. - Cette édition a été complétée par l'Annexe G et le logiciel correspondant.
Električno izolacijski materiali - Lastnosti v zvezi s toplotno vzdržljivostjo - 6. del: Ugotavljanje indeksov toplotne vzdržljivosti (TI - informacijska tehnologija in RTE - radijska in telekomunikacijska oprema) izolacijskega materiala z uporabo metode fiksnih časovnih okvirov (IEC 60216-6:2006)
Ta del IEC 60216 določa eksperimentalne in računske postopke za izpeljavo lastnosti toplotne vzdržljivosti, temperaturnih indeksov (TI) in relativnega indeksa toplotne vzdržljivosti (RTE) materiala z uporabo »metode fiksnih časovnih okvirov (FTFM)«. V tem protokolu staranje poteka pri majhnem številu fiksnih časov z uporabo ustreznega števila temperatur za staranje v vsakem času, lastnosti vzorcev pa se merijo na koncu ustreznega časovnega intervala. To se razlikuje od postopka v IEC 60216-1, kjer staranje poteka pri majhnem številu fiksnih temperatur, meritve lastnosti pa odvisno od napredovanja staranja potekajo po časih staranja. Diagnostični preskusi, uporabljeni pri metodi s fiksnim časovnim okvirom, so omejeni na uničujoče preskuse. Metoda še ne velja za neuničujoče ali dokazne preskusne postopke. TI in RTE, ki se določita po protokolu FTFM, izhajata iz eksperimentalnih podatkov, pridobljenih v skladu z navodili IEC 60216-1 in IEC 60216-2, kot jih spreminja ta standard. Računski postopki in statistični preskusi so spremenjeni glede na tiste v IEC 60216-3 in IEC 60216-5.
