IEC 61249-2-46 Ed. 1.0 b:2018

IEC 61249-2-46:2018 gives requirements for properties of non-halogenated epoxide non°°°woven reinforced core/woven E-glass reinforced surface laminate sheets of thermal conductivity and 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 non-halogenated fire retardants reacted as part of the epoxide polymeric structure. The glass transition temperature is defined to be 105 °°C minimum. Thermal Conductivity is defined to be (1,5 °° 0,2) W/(m°°°K).
