International Standards and Conformity Assessment for all electrical, electronic and related technologies


An amendment is a ratified supplementary document to a European Standard (EN) or Harmonization Document (HD) already circulated to CENELEC national members for national implementation, to be read in conjunction with that EN or HD and which alters and/or adds to previously agreed technical provisions in that EN or HD.

The result of approval of a draft amendment is the publication of a new edition of the EN or HD in question or the publication of an amendment as such, depending on the nature of the amendment. Preference should be given to the issue of a new edition of the standard.

CENELEC national members have the same obligations for implementation and presentation of the amendment as for the EN or HD.
