1. About IEC publications

What is a Redline version?

A Redline version contains both the current IEC standard and a Redline version of the document which shows changes from the previous edition marked in colour. With the Redline you can quickly spot changed sections and tell specifically what has been changed from the previous edition, saving time and avoiding confusion.

The development of a Redline version is not systematic. Criteria are the popularity of the Publication and the clear structure of the changes. If the changes are too much interwoven into the content, a Redline version may be unreadable and thus, lose the benefit of a clear and quick identification of the changes.
