Bibliography
Gives requirements for properties of non-halogenated epoxide woven E-glass reinforced laminated sheets of defined flammability, copper-clad in thicknesses 0,05 mm up to 3,2 mm. The flammability rating is achieved through the use of non-halogenated inorganic and/or organic compounds acting as fire retardants.
