Annotation of standard text STN ISO 7884-8 (700512):

Tato cast mezinarodni normy ISO 7884 urcuje metodu stanoveni (dilatometricke) transformacni teploty tg metodou mereni teplotni roztaznosti. Tato teplota charakterizuje urcity prechodny stav skla z elasticko-krehkeho stavu (za nizkych teplot) do viskozitniho stavu (za vysokych teplot) . Transformacni teplota je uzitecna pri urcovani chladicich postupu a pri odhadovani horni teplotni hranice pouzitelnosti skleneneho zbozi.
