1. About IEC publications

What is a consolidated version (CSV)?

The IEC publishes consolidated versions of its publications with all the amendments included in the base document.

Edition 1.0 base document without any amendments
Edition 1.1 base 1.0 edition consolidated with one amendment
Edition 1.2 base 1.0 edition consolidated with two amendments
Edition 2.0 second edition of a base document.
This may include new information combined as well as amendments from edition 1.x.
Edition 2.1 second edition consolidated with one amendment

Since May 2010, additions and deletions are displayed in red, with deletions being struck through in all new consolidated versions. Since May 2012, the release of the consolidated version is strictly synchronized with that of the amendment.

I have edition 1.2, do I have to buy amendments?

There is no need to buy the amendments because they are already included in the consolidated version.
If you have the base edition (1.0, 2.0, 3.0,…) of a standard, you may purchase amendments separately.
