IEC 61249-4-15:2009给出了预浸料的性能要求，根据IEC 61249-2-35，当根据IEC 62326-4制造多层板时，预浸料主要用作与层压板连接的粘合片。由这些材料组成的多层板适用于无铅组装工艺。这种材料也可用于粘合其他类型的层压板。根据本标准，预浸料具有规定的可燃性（垂直燃烧试验）。完全固化预浸料的可燃性等级是通过使用作为聚合物结构组成部分的溴化阻燃剂实现的。根据供应商的说明固化预浸料后，玻璃化转变温度定义为150°C和200°C。

IEC 61249-4-15:2009 gives requirements for properties of prepreg that are mainly intended to be used as bonding sheets in connection with laminates according IEC 61249-2-35 when manufacturing multilayer boards according to IEC 62326-4. Multilayer boards comprised of these materials are suitable for lead-free assembly processes. This material may also be used to bond other types of laminates. Prepreg, according to this standard, is of defined flammability (vertical burning test). The flammability rating on fully cured prepreg is achieved through the use of brominated fire retardants contained as an integral part of the polymeric structure. After curing of the prepreg according to the supplier's instructions, the glass transition temperature is defined to be 150 °C and 200 °C.
