标准摘要
[中文适用范围]： IEC 61249 的这一部分给出了对溴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，具有规定的可燃性（垂直燃烧测试），覆铜厚度为 0.80 mm 至 1.70 mm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75℃。某些属性要求可能有多个性能等级。需要在采购订单上指定所需的类别，否则可能会提供默认的材料类别。 [外文原描述]： Gives requirements for properties of brominated epoxide cellulose paper reinforced core/woven E-glass reinforced surfaces-laminated sheets of defined flammability, copper-clad in thicknesses of 0,80 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.
