IEC 61249-2-26 Ed. 1.0 b:2005

This part of IEC 61249 gives requirements for properties of non-halogenated epoxide non-woven/woven reinforced E-glass laminated sheets of defined flammability (vertical burning test), copper-clad in thicknesses of 0,80 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 polymeric structure or in addition to it. The glass transition temperature is defined to be 95 ¿C minimum.
