Materials for printed boards and other interconnecting structures - Reinforced base materials clad and unclad. Bismaleimide/triazine modified with non-halogenated epoxide woven glass laminate sheets of defined flammability (vertical burning…1 Scope This part of IEC 61249 gives requirements for properties of bismaleimide triazine modified with non halogenated epoxide woven E glass reinforced laminated sheets of defined flammability (vertical burning test), copper clad in thicknesses of 0,03 mm up to 1,60 mm. The flammability rating is achieved through the use of non halogenated inorganic and or organic compounds acting as fire retardants. These fire retardants are contained as part of
