Materials for printed boards and other interconnecting structures - Reinforced base materials clad and unclad. Brominated epoxide non-woven / woven E-glass reinforced laminate sheets of defined flammability (vertical burning test), copper-clad…1 Scope This part of IEC 61249 gives requirements for properties of brominated epoxide non woven reinforced core woven E glass reinforced surface laminate sheets of defined flammability (vertical burning test), copper clad for lead free assembly in thicknesses of 0,60 mm up to 1,70 mm. The flammability rating is achieved through the use of brominated fire retardants reacted as part of the epoxide polymeric structure. The glass transition temperature
