Foreword
The text of document 65A/473/FDIS, future edition 1 of IEC 61326-2-4, prepared by SC 65A, System
aspects, of IEC TC 65, Industrial-process measurement and control, was submitted to the IEC-CENELEC
parallel vote and was approved by CENELEC as EN 61326-2-4 on 2006-11-01.
The EN 61326 series supersedes EN 61326:1997 + corrigendum September 1998 + A1:1998 + A2:2001
+ A3:2003.
This part of EN 61326 is to be used in conjunction with EN 61326-1:2006 and follows the same
numbering of clauses, subclauses, tables and figures as that standard.
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) 2007-08-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-11-01
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and covers essential requirements of
EC Directive 89/336/EEC. See Annex ZZ.
Annexes ZA and ZZ have been added by CENELEC.
