IEC 61249-2-43:2016给出了规定可燃性（垂直燃烧试验）的非卤化环氧纤维素纸增强芯/编织E玻璃增强表面层压板的性能要求，无铅组装用覆铜板的厚度为0.60 mm至1.70 mm。通过使用作为环氧聚合物结构一部分反应的非卤化阻燃剂，可达到易燃性等级。玻璃化转变温度定义为最低100°C。

IEC 61249-2-43:2016 gives requirements for properties of non-halogenated epoxide cellulose paper reinforced core/woven E-glass reinforced surface laminate sheets of 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 100 °C minimum.
