ISO records it at stage 60.00, International Standard under publication, on 16 October 2026. This page states the public facts, the date used for planning, and the basis for each.

The recorded steps
Only the milestones this site can source are listed: the ballot dates from the FDIS document and the current stage from the ISO feed. Earlier stages are not reproduced, because their dates are not in the feed this site reads and the site does not fill that gap from memory or from someone else's summary. The final row is blank because ISO has not recorded it.
| Stage | What it means | Date | State |
|---|---|---|---|
50.20 | FDIS ballot opened | 20 August 2026 | done |
50.20 | FDIS ballot closed | 15 October 2026 | done |
60.00 | International Standard under publication | 16 October 2026 | now |
60.60 | International Standard published | not recorded | next |
Why the planning date is not the publication date
The brief carried 16 February 2027 as the key date, estimated from the ballot stage. ISO then recorded stage 60.00 on 16 October 2026. The site keeps 16 February 2027 as an outer planning date and shows the stage date as the fact that moves it. The site therefore does three things. It shows the stage date as the fact that moves the plan. It keeps 16 February 2027 as an outer date so that a committee paper has a date to work to. And it labels the outer date as an estimate on every page that carries it, including this one.
The practical reading: treat the stage date as the trigger and the later date as the deadline. If publication lands between the two, the register does not change, only the date on the plan.
What the amendment changes
The amendment adds a mechanism and tightens rules. It does not withdraw any mechanism the base standard already specifies, so there is no re-key on publication and no reason to replace a working deployment for its own sake.

How this record is kept current
A refresh script reads the public ISO feed and compares the designation, title, stage, stage date, committee and ICS with this record. Any difference fails the script loudly and writes the diff. That diff is what the paid watch sends, which is why the watch competes on interpretation rather than on the raw stage: the stage itself is free from ISO.
