Annotation of standard text ČSN EN 60216-8 (346416):

Tato norma specifikuje metody hodnocení stárnutí elektroizolačních materiálů a zjednodušuje metody zjišťování charakteristik tepelné odolnosti (TI - teplotní index, RTI - relativní teplotní index a půlící interval HIC).

Metody specifikují principy vyhodnocování vlastností tepelné odolnosti materiálů dlouhodobě vystavených zvýšené teplotě.

Aplikace této normy předpokládá, že existuje prakticky lineární závislost mezi logaritmem času potřebného ke změně vybrané vlastnosti a převrácenou hodnotou odpovídající absolutní teploty (Arrheniův model).

Pro platnou aplikaci normy by neměly nastávat ve studovaném rozsahu jednotlivé teplotní změny, zejména žádné změny prvního řádu.

V této normě se termínem "izolační materiály" vždy rozumí "izolační materiály a jednoduché kombinace takových materiálů"
