What is a Commented version (CMV)?

Commented version is the only product where the consensus-based content of a publication is enriched with technical information. It is made of a redline version with highlighted areas where technical committee experts provide the reasons and rationale of the most relevant changes. The summary of comments is also provided at the end of the document.

With commented versions, users can better understand the rationale for changes made to the newest edition of the standard. Comments include an explanation for the changes as well as information on the impact of these changes on the application and usability of the standard.

Commented versions are an enhanced version of the traditional IEC Redline Version (RLV) which highlights the changes between the previous edition and the new edition.

  This value-added product consist of a package, which includes both the new edition of the publication, and the commented redline version.
