11、n 5 of IEC 60143-1, prepared by IEC/TC 33 “Power capacitors and their applications“ was submitted to the IEC-CENELEC parallel vote and approved by CENELEC as EN 60143-1:2015. The following dates are fixed: latest date by which the document has to be implemented at national level by publication of an

12、 identical national standard or by endorsement (dop) 2016-04-30 latest date by which the national standards conflicting with the document have to be withdrawn (dow) 2018-07-30 This document supersedes EN 60143-1:2004. The main change with respect to EN is that the endurance test has been replaced by

13、 an ageing test because voltage cycling is already performed in the cold duty test. The guide section has been expanded regarding long line correction and altitude correction. In addition the insulation tables and references to other standards have been updated. Attention is drawn to the possibility

14、 that some of the elements of this document may be the subject of patent rights. CENELEC and/or CEN shall not be held responsible for identifying any or all such patent rights.

46、l committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Te

47、chnical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, govern

48、mental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or

49、 agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be h
