This part of IEC 61249 gives requirements for properties of non-halogenated epoxide non-woven/woven reinforced E-glass laminated sheets of defined flammability (vertical burning test), copper-clad in thicknesses of 0,80 mm up to 1,60 mm. The flammability rating is achieved through the use of non-halogenated inorganic and/or organic compounds acting as fire retardants. These fire retardants are contained as part of polymeric structure or in addition to it. The glass transition temperature is defined to be 95 °C minimum. La presente partie de la CEI 61249 donne les exigences concernant les proprietes des feuilles stratifiees en tissu de verre tisse/non tisse de type E epoxyde non halogene, dinflammabilite definie (essai de combustion verticale) et plaquees cuivre dune epaisseur comprise entre 0,80 mm et 1,60 mm. Les caracteristiques dinflammabilite sont obtenues en utilisant des melanges a base de produits non organiques et/ou organiques non halogenes qui agissent comme des produits ignifuges. Ces produits ignifuges sont contenus par la structure polymere ou sont ajoutes. La temperature de transition vitreuse est definie a 95 °C minimum.
