This European Standard was approved by CENELEC on 2007-03-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

Foreword
The text of document 15/360/FDIS, future edition 2 of IEC 60763-2, prepared by IEC TC 15, Solid
electrical insulating materials, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60763-2 on 2007-03-01.
This European Standard supersedes EN 60763-2:1996.
– the standard has generally been revised editorially and brought into line with EN 60641-2;
– the test method for the determination of the internal ply strength has been replaced with an alternative
method;
– the test method for the determination of the thermal resistance has been enlarged in its scope.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2007-12-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2010-03-01
Annex ZA has been added by CENELEC.
__________
Endorsement notice
