DIN EN IEC 62402:2025-05

This International Standard provides requirements and guidance for obsolescence management applicable to any organization that is dependent on another organization to obtain value from the usefulness of the items that it provides. A cost-effective obsolescence management process and the activities used to implement the process are applicable throughout all phases of an item's life cycle. Guidance on obsolescence management is included as notes, in the informative annexes and references in the Bibliography. This document defines obsolescence differently than the standard dictionary definition. Instead of considering an item to be obsolete or no longer in use, this document defines obsolescence as the transition of a required item that is still in use from being available to no longer being available from the manufacturer. Any item that remains in continuous use is subject to obsolescence. Obsolescence is expressed as difficulty in obtaining supplies, replacement parts, and/or support.
