IEC 61249-2-45:2018给出了非卤化环氧化物非编织增强芯/编织E玻璃增强表面层压板，具有导热性和规定的可燃性（垂直燃烧试验），覆铜，用于厚度为0.60mm至1.70mm的无铅组件。通过使用非卤化阻燃剂作为环氧聚合物结构的一部分进行反应，可达到可燃性等级。玻璃化转变温度定义为最低105°C。导热系数定义为（1,0±0,15）W/（m？K）。

IEC 61249-2-45:2018 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 (1,0 ± 0,15) W/(m？K).
