Anotation

Contains the definitions related to, and the general requirements to be fulfilled by, industrial rigid laminated sheets for electrical purposes, made with any of the following resins as the binder: epoxy (epoxide), melamine, phenolic, polyimide, silicone and unsaturated polyester. The following reinforcements may be used either singly or in combination; cellulosic paper, cotton cloth, glass cloth, glass roving, glass mat, polyester cloth and wood veneers. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. The major changes from the previous edition of IEC 60893-1 are the following: a) new material types have been included; b) changes have been made to the property requirements of some existing types; c) a new method for testing permittivity and dissipation factor has been added; d) all non-specification data for each type has been moved to a new Part 4 of IEC 60893. Contient les definitions apparentees et les exigences generales a respecter pour les planches de stratifies industriels a usages electriques fabriques avec lune des resines suivantes comme liant: resine epoxyde, melamine, phenolique, polyimide, silicone et polyester insature. Les materiaux de renfort suivants peuvent etre utilises, seuls ou combines: papier de cellulose, tissu de coton, tissu de verre, stratifil (roving) de verre, mat de verre, tissu de polyester et placages de bois. Les materiaux conformes a la presente specification satisfont aux niveaux de performances etablis. Cependant, il convient que le choix dun materiau, par un utilisateur, pour une application specifique, soit fonde sur les prescriptions reelles necessaires pour obtenir les performances satisfaisantes pour cette application, et quil ne soit pas fonde sur cette seule specification. Les modifications majeures effectuees par rapport a ledition precedente de la CEI 60893-1 sont les suivantes: a) de nouveaux types de materiaux ont ete introduits; b) des modifications ont ete faites aux prescriptions pour les proprietes de certains types existants; c) une nouvelle methode pour lessai de la permittivite et du facteur de dissipation a ete ajoutee; d) pour chaque type, les valeurs netant pas des specifications ont ete deplacees dans la nouvelle Partie 4 de la CEI 60893.
