IEC 61249-2-42:2010 gives requirements for properties of brominated epoxide non-woven reinforced core/woven E-glass reinforced surface laminate sheets of defined flammability (vertical burning test), copper-clad for lead-free assembly in thicknesses of 0,60 mm up to 1,70 mm. The flammability rating is achieved through the use of brominated fire retardants reacted as part of the epoxide polymeric structure. The glass transition temperature is defined to be 105 °C minimum. La CEI 61249-2-42:2010 fournit des exigences concernant les proprietes des feuilles stratifiees renforcees en verre de type E epoxyde brome non tisse/papier cellulose epoxyde brome, plaquees cuivre, dinflammabilite definie (essai de combustion verticale) pour les assemblages sans plomb et ayant une epaisseur comprise entre 0,60 mm et 1,70 mm. Les caracteristiques dinflammabilite sont obtenues en faisant reagir des ignifuges bromes dans la structure polymere qui font partie de la structure polymere epoxyde. La temperature de transition vitreuse a ete definie comme devant etre de 105 °C au minimum.
