La température de transition vitreuse est définie comme étant de 170 °C au minimum.

Materiali za tiskane plošče in druge povezovalne strukture - 2-40. del: Pokovinjeni in nepokovinjeni ojačeni osnovni materiali - Zelo zmogljive, s stekleno tkanino ojačene laminirane plasti z določeno gorljivostjo (navpični preskus gorljivosti), obdelane z modificirano, nehalogenirano epoksidno smolo, pobakrene, za montažo brez svinca

Ta del standarda IEC 61249 določa zahteve za lastnosti s stekleno tkanino ojačenih pobakrenih laminiranih plasti z določeno gorljivostjo (navpični preskus gorljivosti), obdelanih z modificirano, nehalogenirano epoksidno smolo, z debelino od 0,05 mm do 3,2 mm. Točka posteklenitve je opredeljena kot najmanj 170 °C. Odpornost proti plamenu je opredeljena v smislu zahtev glede vnetljivosti iz točke 7.3. Nekatere zahteve glede lastnosti lahko vključujejo več razredov lastnosti. Želeni razred naj bi bil opredeljen na naročilnici, sicer se dobavi privzeti razred materiala.
