A draft amendment, containing some common modifications to the future IEC 60309-4, was prepared by CENELEC BTWG 112-1, Improvement of EN 60309-1 and EN 60309-2, and was submitted to formal vote. The combined texts were approved by CENELEC as EN 60309-4 on 2007-03-01. This standard is to be read in conjunction with EN 60309-1:1999 + A1:2007 and EN 60309-2:1999 + A1:2007. Part 1 comprises clauses of a general character and the subsequent parts of the series deal with particular types. The clauses of the subsequent parts supplement or modify the corresponding clauses in Part 1. Where the text of subsequent parts indicates an “addition“ to or a “replacement“ of the relevant requirement, test specification or explanation of Part 1, these changes are made to the relevant text of Part 1, which then becomes part of the standard. Where no change is necessary, the words “This clause of Part 1 is applicable“ are used. Clauses, subclauses, figures, tables and notes which are additional to those in Part 1 are numbered starting from 101. 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or by endorsement (dop) 2008-03-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2010-03-01 Annexes ZA and ZB have been added by CENELEC. _ Licensed Copy: London South Bank University, London South Bank University, Wed Aug 08 03:59:36 GMT+00:00 2007, Uncontrolled Copy, (c) BSI 3 EN 60309-4:2007 Endorsement notice The text of the International Standard IEC 60309-4:2006 was approved by CENELEC as a European Standard with agreed common modifications.
