15、-105, prepared by SC 17A, “High-voltage switchgear and controlgear“, of IEC TC 17, “Switchgear and controlgear“ was submitted to theIEC-CENELEC parallel vote and approved by CENELEC as EN 62271-105:2012. The following dates are fixed: latest date by which the document has to be implemented at nation
16、al level bypublication of an identical national standard or by endorsement (dop) 2013-08-01 latest date by which the national standards conflicting with the document have to be withdrawn (dow) 2015-11-01 This document supersedes EN 62271-105:2003. EN 62271-105:2012 includes the following significant
17、 technical changes with respect to EN 62271-105:2003: implementation of figures at the place where they are cited first; renumbering of tables; addition of some of the proposals from IEC paper 17A/852/INF; addition of missing subclauses of EN 62271-1; implementation of 6.105 “Extension of validity o
18、f type tests“ and consequently removing of the relevantparts in the different existing clauses; change of 7thparagraph of 6.101.4 as there is now a definition of NSDD given in 3.7.4 of EN 62271-1:2008. Harmonization with EN 62271-107; some referenced clauses in other standards like EN 60282-1 were c
19、hanged and therefore changed theeditions under 1.2 to the ones referred to; addition of a new Annex C defining tolerances. This standard is to be read in conjunction with EN 62271-1:2008, to which it refers and which isapplicable, unless otherwise specified in this standard. In order to simplify the
20、 indication of correspondingrequirements, the same numbering of clauses and subclauses is used as in EN 62271-1. Amendments tothese clauses and subclauses are given under the same numbering, whilst additional subclauses arenumbered from 101. Attention is drawn to the possibility that some of the ele
