Part 1 and the publication transition
Checked 23 October 2026: ISO 2768-1:1989 is still marked Published. The successor ISO 2768 page has an edition field of 2026-10 but remains Under publication, stage 60.00. Follow the drawing/contract rather than silently switching editions.
Part 2 is a different issue
ISO 2768-2:1989 is withdrawn, with ISO 22081:2021 listed as its successor. ISO 22081 concerns general geometrical and size specifications; it does not simply replace every numeric Part 1 table.
Before selecting a numeric limit
Check whether the feature already has an individual tolerance, whether the manufacturing/feature scope is covered, which class is explicitly invoked and which nominal-length or angle interval applies. Then consult that edition’s actual table.
What this page can establish
The linked public catalogue verifies scope and lifecycle only. Numeric general-tolerance tables have not been fully reviewed here, so this page does not invent a tolerance for an unspecified class or feature.
