IEC Commented Redlines

The Commented Redline Version (CMV) is a new IEC value-added product. With the Commented Redline Version, stakeholders can view comments on the major changes between the previous edition and the new edition of the publication, including the committee's explanation and rationale for changes. CMVs can also include information on the impact of the changes on the application and usability of the standard. CMVs consist of a package, which includes both the new edition of the publication, and the Commented Redline Version. With the addition of comments on the major changes, CMVs are an enhanced version of the traditional IEC Redline Version (RLV), which highlight only the changes between the previous edition and the new edition. The creation of CMVs is a direct result of requests by end-users of IEC International Standards and is part of an ongoing effort by IEC to better serve the community's needs.

Listed below are all of the currently available IEC commented redlines.
