Materials for printed boards and other interconnecting structures - Part 2-10: Reinforced base materials, clad and unclad - Cyanate ester, brominated epoxide, modified or unmodified, woven E-glass reinforced laminated sheets of defined flammability (vertical burning test), copper-clad

Gives requirements for properties of cyanate ester, brominated epoxide modified or unmodified woven E-glass laminate sheets of defined flammability, copper-clad, in thicknesses of 0,05 mm to 3,2 mm. The flammability rating is achieved through the use of brominated fire retardants contained as an integral part of the epoxide polymeric structure.

Donne les prescriptions concernant les propriétés des feuilles stratifiées en ester de cyanate et tissu de verre de type E époxyde bromé modifié ou non modifié, d'inflammabilité définie plaquées cuivre, ayant une épaisseur comprise entre 0,05 mm et 3,2 mm. Les caractéristiques d'inflammabilité sont obtenues en utilisant des ignifuges bromés contenus dans la structure polymère époxyde.

This European Standard was approved by CENELEC on 2003-04-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.
