Drafting IEC publications



Creating amendments

Amendments bring technical changes to an IEC publication. They are not designed to be used for correcting editorial problems.

An amendment consists of

  • a foreword (use the corresponding autotext from the IEC template)
  • in certain cases an introduction
  • instructions concerning the changes to be made
  • new or replaced text

Any part of the document (titles, clauses, subclauses, tables, figures etc.) can be either replaced or deleted, or new text can be added. Possible instructions are Add, Delete, Insert and Replace. Do not use Modify or Amend.


When creating an amendment, please indicate where the change takes place and what needs to be changed, according to the following scheme:

  • location
  • instructions
  • new or replaced text (where applicable)

To indicate the location, use the numbering of elements (clauses, subclauses, figures and tables) from the previous edition. Do NOT refer to the page numbers.


Numbering existing and new elements

When an existing clause, subclause, figure or table is replaced, the old number is retained.


When a new clause, subclause, term, figure or table is added, the existing ones will not be re-numbered, as updating cross-references can be very problematic.


New elements have to be numbered sequentially, starting from the last available number +1. Only at the time of the next new edition will the numbering be updated.



When inserting a new figure in a document containing 45 figures, write:
Add, between Figures 25 and 26, the following new Figure 46: [figure]

do not write:
Add, after Figure 25, the following new Figure 26. Renumber the remaining figures and cross-references as Figures 27 to 46.
