标准摘要
[中文适用范围]： 本部分IEC 61249规定了厚度在0.03 mm至1.60 mm之间的，采用非卤代环氧树脂改性双马来酰亚胺/三嗪编织E玻璃纤维增强的，具有规定阻燃性（垂直燃烧试验）的铜层压板材（包括贴铜和不贴铜基材）的性能要求。阻燃性能等级是通过使用无机和/或有机非卤代化合物作为阻燃剂来实现的。这些阻燃剂包含在聚合物结构中或作为其组成部分。玻璃化转变温度定义为至少160°C。某些性能要求可能有几个性能等级。所需的等级应在采购订单中指定，否则可能提供材料的默认等级。 [外文原描述]： IEC 61249-2-27:2012 gives requirements for properties of bismaleimide/triazine modified with non-halogenated epoxide woven E-glass reinforced laminated sheets of defined flammability (vertical burning test), copper-clad in thicknesses of 0,03 mm up to 1,60 mm. The flammability rating is achieved through the use of non-halogenated inorganic and/or organic compounds acting as fire retardants. These fire retardants are contained as part of polymeric structure or in addition to it. The glass transition temperature is defined to be 160 °C minimum.
