Gives requirements for properties of bismaleimide/triazine modified epoxide, or unmodified, woven E-glass reinforced 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 fire retardants contained as an integral part of the epoxide polymeric structure.
