Numerotation des publications
Publication numbering
Depuis le 1er Janvier 1997. les publications de la CEI
sont numerotees a partir de 60000. Ainsi. la CEI 34-1
devient la CEI 60034-1.
As from 1 January 1997 all IEC publications are
issued with a designation in the 60000 series. For
example. IEC 34-1 is now referred to as IEC 60034-1.
Editions consolidees
Consolidated editions
Les versions consolidees de certaines publications de la
CEI incorporant les amendements sont disponibles. Par
exemple, les numeros d'edition 1.0, 1.1 et 1.2 indiquent
respectivement la publication de base, la publication de
base incorporant I'amendement 1, et la publication de
base incorporant les amendements 1 et 2.
The IEC is now publishing consolidated versions of its
publications. For example, edition numbers 1.0, 1.1
and 1.2 refer, respectively, to the base publication,
the base publication incorporating amendment 1 and
the base publication incorporating amendments 1
and 2.
