Plain answer

When will ISO 27091 be published?

ISO has not recorded a publication date. The record shows stage 50.00 on 13 July 2026. This site plans to 18 February 2027 as an estimate, labelled wherever it appears, and watches the stage record for the real date.

The stage record

ISO records the project from 10.99 new project approved on 3 February 2023, through the working drafts, the committee draft and the DIS, to 50.00 on 13 July 2026. The DIS ballot closed on 26 February 2026 and the full report approved the draft for registration as an FDIS on 8 July 2026.

The remaining stages

Stages 50.20, 50.60, 60.00 and 60.60 are listed without a date. The FDIS ballot and publication come next, but ISO has not recorded when. Any date before that is a plan, not a fact.

Why the date is an estimate

The site uses 18 February 2027, 120 days from the build date, because a plan needs a date. It is derived from the stage and the public expectation of publication in 2027. It is not an ISO commitment and no page treats it as one.

What to do about it

Do the work that will be right under either the draft or the published text, and put the stage on the change watch. The watch reads the ISO stage feed and emails only when the stage, its date or the record changes.
