Consolidated versions (CSV)

A Consolidated version (CSV) allows users to access technical content from multiple publications that have been merged into a single, user-friendly product.

The CSV incorporates the content of amendment(s) into the publication. The track changes mode shows where the publication has been modified by the amendment. The release of the CSV is synchronized with the release of the amendment.

Maintenance - A CSV is automatically withdrawn when the official publication is withdrawn

Key point - CSVs are derived from official publications, without modification of the original consensus-based technical content. The IEC Secretariat guarantees the accuracy of their technical content.

Redline version (RLV)

A Redline version (RLV) allows users to easily access the changes between the new and previous edition of a publication.

Maintenance - An RLV is automatically withdrawn when the official publication is withdrawn.

Key point - Not every standard is available as an RLV. If the changes to the text are extensive, a redline version becomes unreadable and the RLV benefit of an easy identification of changes lost.
