IEC 61249-4-11:2005 标准规定了一种非卤素环氧树脂、玻璃纤维预浸料的定义可燃性。该预浸料适用于制造印制电路板和其他互连结构。该标准的目的是确保预浸料的可燃性符合特定的要求，以确保印制电路板和其他互连结构的安全性和可靠性。

该标准规定了预浸料的物理和化学性质，包括玻璃转移温度、热分解温度、含水率、树脂含量、挥发物含量、电气性能等。此外，该标准还规定了预浸料的可燃性测试方法，包括垂直燃烧测试、水平燃烧测试和热分解测试。

该标准要求预浸料的可燃性符合特定的要求，包括垂直燃烧测试的最大火焰高度、水平燃烧测试的最大火焰前进速度和热分解测试的最大热释放速率。这些要求旨在确保预浸料在使用过程中不会引起火灾或爆炸。

IEC 61249-4-11:2005 标准适用于制造印制电路板和其他互连结构的预浸料。该标准的要求适用于所有使用该预浸料制造的印制电路板和其他互连结构。此外，该标准还规定了预浸料的包装、标记和存储要求。
