CENELEC members

10、 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

11、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

12、the same status as the official versions.

Foreword The text of document 15/390/CDV, future edition 2 of IEC 60641-3-1, prepared by IEC TC 15 “Solid electrical insulating materials“, was submitted to the IEC-CENELEC parallel vote and

14、was approved by CENELEC as EN 60641-3-1 on 2008-08-01. This European Standard supersedes EN 60641-3-1:1994. The main changes with respect to EN 60641-3-1:1994 are listed below: requirements for types B.0.3 and B.5.3 were added; the precompressed type B.3.1 was divided in B.3.1A and B.3.1B (higher fl

15、exibility); types B.6.1 has been replaced with a new type, but the designation has been kept; type B.7.1 has been deleted; the thickness relation of the properties has been simplified; the values were adjusted to todays needs of users. The following dates were fixed: latest date by which the EN has

16、to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2009-05-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-08-01 Annex ZA has been added by CENELEC. _ Endorsement notice The text of the I
