IEC？61249-2-46:2018（E）给出了非卤代环氧化物非？具有导热性和规定可燃性（垂直燃烧试验）的编织增强芯/编织E-玻璃增强表面层压板，用于无铅组装，厚度为0,60？毫米高达1.70？嗯。通过使用作为环氧化物聚合物结构的一部分反应的非卤化阻燃剂来实现可燃性等级。玻璃化转变温度定义为105？最低°C。导热系数定义为（1,5±0,2）？W/（m？K）。

IEC？61249-2-46:2018(E) 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).
