Annotation of standard text IEC 61249-2-23-ed.1.0 :

This part of IEC 61249 gives requirements for properties of non-halogenated phenolic cellulose paper copper-clad laminated sheets, economic grade, in thicknesses of 0,8 mm up to 3,2 mm. This standard covers materials with different requirements on flammability and are designated according to the following: Material 61249-2-23-1: general purpose grade, requirement on flammability not specified; Material 61249-2-23-2: materials of defined flammability (vertical burning test). These grades of material provide for one of two flammability requirements and designated as FV0 or FV1 in Table 8. La presente partie de la CEI 61249 indique les exigences concernant les proprietes des feuilles stratifiees renforcees en papier cellulose phenolique non halogene, de qualite economique, plaquees cuivre depaisseur comprise entre 0,8 mm et 3,2 mm. Cette norme couvre les materiaux possedant differentes exigences sur linflammabilite et ils sont concus selon ce qui suit: Materiau 61249-2-23-1: qualite dusage courant, exigence sur linflammabilite non specifie; Materiau 61249-2-23-2: materiaux dinflammabilite definie (essai de combustion verticale). Cette qualite de materiaux est prevue pour une des deux exigences dinflammabilite et designees par FV0 ou FV1 dans le Tableau 8.
