The IEEE Standards Association (IEEE-SA) introduces IEEE Redline Versions of Standards, a new offering that provides an easier way to compare all of the changes, made during the standards revision process, between an active standard and the previous approved version. IEEE Standards are revised when any of the material in the standard becomes obsolete or incorrect.
Additions, deletions, and other formatting and/or content revisions are clearly displayed as underlined and strikethrough texts, ensuring all changes made between the two documents are quickly and easily identified.
These documents enable technical professionals to efficiently and effortlessly implement changes to procedures, equipment and products saving time and resources.
It is no longer necessary to read through the entire standard (word-for-word, table-for-table) to figure out what has 
changed. If a user is already familiar with a standards, the review process is increased by concentrating only on what has changed by skipping to the clearly marked revisions indicated.
Over 100 Redline Versions are available for IEEE standards that have been revised, as far back as the year 2007. As more IEEE standards are revised, a corresponding Redline Version will be made available.
IEEE Redline Versions are accessible through several channels:
- Subscribers to IEEE/IET Electronic Library (IEL), IEEE Standards Online and IEEE Standards Choice are able to access PDF Redline Versions with your current subscription by browsing or searching in IEEE Xplore.
- Individual “Base + Redline” bundles are available for sale in the IEEE Standards Store. Each bundle contains the active standard (Base) and the redline version of the standard (Redline).
(Note: It may not be technically possible to capture all revisions accurately, please consult previous versions of the standard as appropriate. In all cases, only the current active version of the standard is considered the official document.)
