标准摘要
[中文适用范围]: IEC 61249-2-44 规定了用于无铅组装的卤化环氧非编织/编织 E 玻璃纤维增强层压板(垂直燃烧测试,铜层压)在 0.60 mm 至 1.70 mm 厚度范围内的性能要求。阻燃特性通过作为环氧聚合物结构一部分反应的非卤化阻燃剂实现。玻璃化转变温度定义为最低 105 °C。某些性能要求可能有多个性能等级。所需的等级应在采购订单上指定,否则将提供材料的默认等级。 该部分 IEC 61249 标准规定了用于无铅组装的无卤环氧非编织/编织 E 玻璃纤维增强层压板(垂直燃烧测试,铜层压)在 0.60 mm 至 1.70 mm 厚度范围内的性能要求。阻燃特性通过作为环氧聚合物结构一部分反应的非卤化阻燃剂实现。玻璃化转变温度定义为最低 105 °C。某些性能要求可能有多个性能等级。所需的等级应在采购订单上指定,否则将提供材料的默认等级。 [外文原描述]: IEC 61249-2-44:2016 gives requirements for properties of non-halogenated epoxide non-woven 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 105 °C minimum.
