IEC 61249-2-39:2012标准规定了高性能环氧树脂和非环氧树脂，编织E玻璃层压板材料的定义可燃性（垂直燃烧试验），铜覆盖用于无铅组装的要求和试验方法。本标准适用于制造印制电路板和其他互连结构的材料。

本标准要求材料必须符合垂直燃烧试验的要求。垂直燃烧试验是一种评估材料可燃性的标准试验方法。在试验中，材料垂直放置，点燃材料的下端，然后观察材料的燃烧情况。本标准要求材料在试验中不能燃烧到试验装置的上端，并且不能滴落燃烧物质。

本标准还要求材料必须符合无铅组装的要求。无铅组装是一种环保的电子元器件组装方式，要求使用不含铅的焊料。本标准要求材料必须能够与无铅焊料良好地结合，并且在无铅焊接过程中不会发生热分解或其他不良反应。

本标准还要求材料必须符合铜覆盖的要求。铜覆盖是一种保护材料表面的方法，可以提高材料的耐腐蚀性和导电性。本标准要求材料的铜覆盖必须符合相关的标准要求，并且在无铅焊接过程中不会发生剥落或其他不良反应。

总之，IEC 61249-2-39:2012标准规定了高性能环氧树脂和非环氧树脂，编织E玻璃层压板材料的定义可燃性（垂直燃烧试验），铜覆盖用于无铅组装的要求和试验方法。该标准的要求可以保证材料的可靠性和稳定性，适用于制造印制电路板和其他互连结构的材料。
