IEC 61249-2-1-ed.1.0

Annotation of standard text IEC 61249-2-1-ed.1.0 :

This part of IEC 61249 gives requirements for properties of phenolic cellulose paper reinforced 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, designated according to the following: Material 61249-2-1-1: general purpose grade, requirement on flammability not specified; and Material 61249-2-1-2: materials of defined flammability (vertical burning test). These grades of material cover one of two flammability requirements, designated at FV0 or FV1. La presente partie de la CEI 61249 indique les exigences concernant les proprietes des feuilles stratifiees renforcees en papier cellulose phenolique, de qualite economique, plaquees cuivre et depaisseur comprise entre 0,8 mm et 3,2 mm. Cette norme couvre les materiaux possedant differentes exigences sur linflammabilite et concus selon ce qui suit: Materiau 61249-2-1-1: qualite dusage courant, exigence sur linflammabilite non specifiee et Materiau 61249-2-1-2: materiaux dinflammabilite definie (essai de combustion verticale). Ces qualites de materiau couvrent une des deux exigences dinflammabilite nommees FV0 ou FV1.
