IEC 61249-2-33:2009 specifies requirements for properties of non-halogenated modified epoxy woven E-glass laminate sheet of a thickness of 0,05 mm up to 3,2 mm, of defined flammability (vertical burning test), copper-clad. The glass transition temperature is defined to be 150 °C minimum. The relative permittivity is equal to or less than 4,1 and the dissipation factor is equal to or less than 0,0120 at 1 GHz. La CEI 61249-2-33:2009 specifie des exigences concernant les proprietes des feuilles stratifiees en tissu de verre de type E epoxyde modifie non halogene, plaquees cuivre, dinflammabilite definie (essai de combustion verticale) et ayant une epaisseur comprise entre 0,05 mm et 3,2 mm. La temperature de transition vitreuse est definie a 150 °C minimum. La permittivite relative est inferieure ou egale a 4,1 et le facteur de dissipation est inferieur ou egal a 0,0120 a 1 GHz.
