Annotation of standard text IEC 61249-2-21-ed.1.0 :

Gives requirements for properties of non-halogenated epoxide woven E-glass reinforced laminated sheets of defined flammability, copper-clad in thicknesses 0,05 mm up to 3,2 mm. The flammability rating is achieved through the use of non-halogenated inorganic and/or organic compounds acting as fire retardants. Indique les exigences concernant les proprietes des feuilles stratifiees en tissu de verre de type E epoxyde non halogene ayant une epaisseur comprise entre 0,05 mm et 3,2 mm, plaquees cuivre, dinflammabilite definie. Les caracteristiques dinflammabilite sont obtenues en utilisant des melanges a base de produits non organiques et/ou organiques non halogenes.
