Title Materials for printed boards and other interconnecting structures - Part 4-11: Sectional specification set for prepreg materials, unclad - Non-halogenated epoxide, woven E-glass prepreg of defined flammability
Project Number 15949
Abstract/Scope This part of EN 61249 gives requirements for properties of prepreg that is mainly intended to be used as bonding sheets in connection with laminates according EN 61249-2-7 when manufacturing multilayer boards according to EN 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 non-halogenated fire retardants contained as an integral part of the polymeric structure. After lamination according to the supplier's instructions, the glass transition temperature is defined to be 120 C minimum.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved


(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat


(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level


(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement


(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
