2. Search and find publications

What is the validity of IEC publications?

The search results mention a Stability date for some publications. The contents of the publications will remain unchanged up to the Stability date. At this date, the publication will be either reconfirmed, withdrawn, replaced by a revised edition or amended. If there is a revision or amendment on-going then this is mentioned under the publication in the “Work in progress” tab, if you don't see this tab it means that there is no project under development.

Stability periods are based on an assessment of the maturity of the technology and future, foreseen changes due to development or maintenance of associated publications. Typically stability periods are between 3 and 12 years. If a committee needs to process an amendment or revision before the review date, it may decide to advance the review date and modify the stability date accordingly.
