What Is an ISO Amendment?
To accommodate for needed revisions, ISO international standard documents are periodically reviewed. The result of this revision process often culminates in the standard being reaffirmed or revised, the latter option resulting in the release of the revision as a new edition of the document. However, the ISO/IEC Directives allow for several means of modifying standards:
“A published International Standard may subsequently be modified by the publication of
- a technical corrigendum;
- a corrected version;
- an amendment; or
- a revision (as part of the maintenance procedure in 2.9).
NOTE In case of revision, a new edition of the International Standard will be issued.”

Under these directives, amendments are one of the primary means by which standards can be changed. Specifically:
“An amendment alters and/or adds to previously agreed technical provisions in an existing International Standard and its prior amendment, if any. An amendment is considered a partial revision: the rest of the International Standard is not open for comments.
An amendment is normally published as a separate document, the edition of the International Standard affected remaining in use.”

.The Directives also detail the following information for corrections and corrigendum:
“A correction is only issued to correct an error or ambiguity inadvertently introduced either in drafting or in publishing and which could lead to the incorrect or unsafe application of the publication.
Corrections are not issued to update information that has become outdated since publication.”
