What is fixed
The DIS was registered on 23 January 2026. The ballot opened on 1 April 2026 and closed on 25 June 2026. The record stands at 40.60. The project was approved on 24 April 2024, and the committee is ISO/IEC JTC 1/SC 7, Software and systems engineering.
What is not fixed
No publication date is published. The next public event is a decision on the DIS: referral back (40.92 or 40.93) or approval for registration as an FDIS (40.99). Until that appears in the record, any date is a planning assumption, including the one on this site.
How to read the planning date
The date 14 September 2027 is 328 days from the build date and about fifteen months after the close of the DIS ballot. It leaves room for an FDIS ballot, a proof stage and publication. It is not an ISO date, and this site will replace it the moment ISO publishes one.

Stage and dates in full
The checkpoints, what each stage code means and the earliest and latest case for publication.
Edition 1: what it means
No predecessor, no transition from an earlier 26517, and no certificate replaced. What that changes for a team.
The 2651x family
Where 26517 sits beside 26511, 26512, 26513, 26514, 26515, 26516 and 26531, with each status.
What changes the plan
| Event | What it changes | What to do |
|---|---|---|
| 40.92 or 40.93, referred back | The ballot did not approve the DIS, or a new ballot is decided | Keep the plan, re-date the estimate and watch for the next ballot. |
| 40.99, approved for FDIS | The draft text is close to final | Read the FDIS text and map it to the plan; the requirement wording becomes the thing to follow. |
| 40.92, referred back | The ballot did not approve the DIS | Keep the plan, re-date the estimate and watch for a new ballot. |
| 60.60, published | The standard is published | Read the published edition, retire the draft assumptions and update the register. |
