ISO/IEC 81346 – Reference Designation System for Industrial Systems
Learn how the ISO/IEC 81346 standard creates a common structure for identifying systems, equipment and components across engineering, documentation and lifecycle management.
ISO/IEC 81346 is an international standard for structuring and identifying industrial systems and equipment. It provides a consistent reference designation system that improves engineering communication, reduces documentation errors and supports collaboration across disciplines and organizations.
Built on trust. Backed by results
Why is a common engineering language important?
Imagine trying to run a symphony without sheet music - many engineering projects face that every day.
As a project expands, complexity naturally rises. It’s never too late to introduce a shared naming system so all engineering teams use consistent terminology and can exchange data smoothly.
