IEC 61249-2-32:2009 specifies requirements for properties of modified epoxide 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 3,7 and the dissipation factor is equal to or less than 0,0070 at 1 GHz. La CEI 61249-2-32:2009 specifie des exigences concernant les proprietes des feuilles stratifiees en tissu de verre de type E epoxyde modifie, 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 comme etant de 150 °C au minimum. La permittivite relative est inferieure ou egale a 3,7 et le facteur de dissipation est inferieur ou egal a 0,0070 a 1 GHz.
