IEC Standards

The International Electrotechnical Commission (IEC) is a non-profit, non-governmental international standards organization that prepares and publishes International Standards for all electrical, electronic and related technologies collectively known as "electrotechnology".

The IEC is made up of members, called national committees, and each NC represents its nation's electrotechnical interests in the IEC.

What is a Commented version (CMV)?

The Commented Version (CMV) is the only product where the consensus-based content of a publication is enriched with technical commentary. It is made of a Redline Version with highlighted areas where technical committee experts provide the reasons and rationale of the most relevant changes. The summary of comments is also provided at the end of the document.

With CMVs, users can better understand the rationale for changes made to the newest edition of the standard. Comments include an explanation for the changes as well as information on the impact of the changes on the application and usability of the standard. Check out IEC CMVs here !
