Foreword
This Harmonization Document was prepared by WG 9 of the Technical Committee CENELEC TC 20,
Electric cables.
The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC as
HD 602 S2 on 2009-12-01.
It supersedes HD 620 S1:1996, A1:2001, A2:2003 and A3:2007 plus its corrigendum of Dec. 2007.
In this revision of HD 620 the previous Parts 5 and 6 have been consolidated to become Part 10, and Parts 7
and 8 likewise to become Part 11.
Users of HD 620 should note that, in accordance with the decision of the Technical Board (D130/040),
national standards implementing one or more particular sections of HD 620 may be further updated in
advance of future amendments to the published version of the HD. This is explained more fully in document
TC20/Sec1596/R. This document is available via National Committees and will be updated on an annual
basis.
The following dates were fixed:
– latest date by which the HD has to be implemented

at national level by publication of a harmonized

national standard or by endorsement
(dop) 2010-12-01
– latest date by which the national standards conflicting

with the HD have to be withdrawn
(dow) 2012-12-01
By decision of the Technical Board (D81/139 extended by D104/118 & D114/076) this HD exists only in
English.
