标准摘要
[中文适用范围]： IEC 61249 的第部分规定了用于无铅组装的、厚度在0.60毫米至1.70毫米之间的、具有特定可燃性（垂直燃烧测试）的非卤素环氧纤维素纸增强芯/织造E玻璃纤维增强表面层压板片的性能要求。该可燃性评级是通过将非卤素阻燃剂反应作为环氧聚合物结构的一部分来实现的。玻璃化转变温度定义为至少100°C。某些性能要求可能有几个性能等级。所需等级应在采购订单中指定，否则将供应默认等级材料。 [外文原描述]： 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.
