National annex

A country-specific supplement to an international standard that fills in local details, such as naming codes in ISO 19650.
Updated 5 November 2026Draft · awaiting review

A national annex adds country-specific requirements to an international standard. ISO 19650 leaves some details open — container naming fields, status and revision codes, and more — and national annexes define them.

The UK National Annex to ISO 19650-2 is the most widely used and is adopted by many projects outside the UK. Projects should state which annex, if any, applies.
