15、d to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60239 on 2005-07-01. This European Standard supersedes EN 60239:1997. Significant technical changes with respect to EN 60239:1997 are as follows: addition of 750 mm nominal diameter electrodes; revision of electrode diameter and le
16、ngth tolerances; revision of nominal lengths and diameters; introduction of socket and pin tolerances; revision of Annex A on male-female electrodes; addition of Annex B on handling and jointing. This new edition also aims at a better compatibility between EN 60239 and other technical standards that
17、 cover the same subject, as well as better compliance with standards for figures, tables and symbols in that respect, and in addition to the content, the format and the title of this standard have been modified. The following dates were fixed: latest date by which the EN has to be implemented at nat
18、ional level by publication of an identical national standard or by endorsement (dop) 2006-04-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2008-07-01 Annex ZA has been added by CENELEC. _ Endorsement notice The text of the International Standard IE
