Annotation of standard text IEC 61249-4-2-ed.1.0 :

This part of IEC 61249 gives requirements for properties of prepreg that is mainly intended to be used as bonding sheets in connection with laminates according to IEC 61249-2-8 when manufacturing multilayer boards according to IEC 62326-4. This material may be also 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 suppliers instructions, the glass transition temperature is defined as 150 °C minimum.
