标准摘要
[中文适用范围]: IEC 61249 的这一部分给出了对具有规定可燃性(垂直燃烧测试)的溴化环氧纤维素纸增强芯/编织无碱玻璃增强表面层压板的性能要求,铜包层用于无铅组装,厚度为 0.60 毫米以上至 1,70 毫米。可燃性等级是通过使用作为环氧化物聚合物结构的一部分发生反应的溴化阻燃剂来实现的。玻璃化转变温度定义为最低 100 °C。某些属性要求可能有多个性能等级。应在采购订单上指定所需的类别,否则将提供默认的材料类别。 [外文原描述]: IEC 61249-2-41:2010 gives requirements for properties of brominated 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 brominated fire retardants reacted as part of the epoxide polymeric structure. The glass transition temperature is defined to be 100 °C minimum.
