13、, Evaluation and qualification of electrical insulating materials and systems, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60216-5 on 2008-05-01. This European Standard supersedes EN 60216-5:2003. EN 60216-5:2008 clarifies and corrects a few items and adds an Ann
14、ex D which provides criteria for the selection of the reference (or reference EIM). EN 60216-5:2008 provides instructions for deriving a provisional estimate of the temperature up to which a material may give satisfactory performance in an application (by comparative thermal ageing with a material o
15、f known performance). This standard is to be used in conjunction with EN 60216-1, EN 60216-2 and EN 60216-3. 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) 2009-02-01 latest
16、date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-05-01 Annex ZA has been added by CENELEC. _ Endorsement notice The text of the International Standard IEC 60216-5:2008 was approved by CENELEC as a European Standard without any modification. _ BS EN 60216-5
