ISO 9001:2026 and calibration: what changed and what to check

9 min read Published

ISO 9001:2026 changes very little for calibration: clause 7.1.5 keeps its number and title, UKAS rates no change to the requirements of clause 7.1.5.1, and clause 7.1.5.2 has a minor change and a new title, Traceability of measurement results. Organizations certified to the 2015 edition have until September 30, 2029 to transition, so the practical work is to read the new clause text and update whatever quotes the old one.

What did ISO 9001:2026 change for calibration?

ISO published ISO 9001:2026, the sixth edition, on September 16, 2026. It replaces ISO 9001:2015 and its 2024 amendment over a three-year transition. The clearest public evidence for calibration is the high-level gap analysis that UKAS, the UK accreditation body, published for certification bodies. It rates the extent of change to the requirements of each clause as no change, minor or significant.

For calibration the result is short. Clause 7.1.5, Monitoring and measuring resources, keeps its number and title. UKAS rates clause 7.1.5.1, General, as no change. Clause 7.1.5.2 goes from Measurement traceability to Traceability of measurement results, and UKAS rates it as minor. Global ACI, the successor to the IAF, lists the key changes in its mandatory transition document, Global ACI-TECH-3-TR 2029-09-30 (M). Clause 7.1.5 is not on that list, although the list is not exhaustive.

The larger changes sit elsewhere. UKAS names interested parties, quality culture and ethical behavior, risks and opportunities, planning of changes and management review as the most significant. Annex A, which is informative, has been revised to clarify the requirements, and Annex B has been removed.

Of the documents we could read, UKAS states only the new title of clause 7.1.5.2 and its rating. It does not say what else moved inside it, and the standard is a paid document. Check the wording in your own copy rather than relying on any summary, this one included.

Which clauses touch a calibration program?

The table lists the clauses a calibration program meets most often, with the rating from the UKAS gap analysis. The right-hand column is our practical reading. It is not text from the standard.

ISO 9001:2026 clauses that touch a calibration program, with the UKAS rating and what to check
Clause in ISO 9001:2026UKAS ratingWhat to check
7.1.5.1 GeneralNo changeUKAS rates no change to the requirement. Read the 2026 text before keeping any wording you quote. Keep your proof that gages suit their job and stay that way.
7.1.5.2 Traceability of measurement resultsMinorNew title. Read the clause and update any procedure or form that quotes the old title.
7.5 Documented informationNo changeGlobal ACI notes a new phrase for documented information and a clarified use of the words shall be available. It does not tie this to a clause, so it may appear wherever records are required. Read the wording wherever a procedure quotes a record requirement.
6.3 Planning of changesSignificantGlobal ACI says planned changes now cover how effectiveness is monitored, how the change is communicated and how results are reviewed. Apply that when a change touches calibration, such as a new records system.
7.3 AwarenessSignificantGlobal ACI says it now includes quality culture and ethical behavior. That reaches the people who calibrate and use gages.
8.4.3 Information for external providersMinorCompare what you tell calibration suppliers, such as purchase order requirements, with the new text. Clauses 8.4.1 and 8.4.2 are rated no change.
8.7 Control of nonconforming outputsNo changeHandling of product affected by a failed gage stays the same.
9.3.2 Management review inputsSignificantGlobal ACI says the inputs now read shall include, with a new input on changing needs of interested parties. If calibration results feed the review, check them against the new list.
10.2 Nonconformity and corrective actionNo changeCorrective action after a calibration failure stays the same.

What stays the same?

Given the UKAS ratings, expect the calibration obligations your program already meets to carry over. Here is what they come to in practice, in our words, based on ISO 9001 clause 7.1.5 in the 2015 edition. Confirm each one against the 2026 wording.

  • Keep proof that each gage suits its job and has stayed that way (clause 7.1.5.1).
  • Decide which gages need a traceable calibration or a verification, and how often or whether before each use. If there is nothing to trace to, write down what you relied on instead (clause 7.1.5.2).
  • Make it possible to tell whether a gage is good to use.
  • Protect the setting from tampering and the gage from rough handling.
  • When a gage turns out to be bad, look back at what it measured and deal with anything that may be wrong.
Tip: Neither the UKAS table nor the Global ACI list of key changes asks you to recalibrate equipment or reissue certificates because of the new edition.

What should a quality manager do now?

  1. Buy ISO 9001:2026 from ISO or your national standards body, then read clause 7.1.5 in full against your calibration procedure.
  2. Change any procedure, form or internal audit checklist that quotes the old clause title. A reference by number alone, such as clause 7.1.5.2, can stay.
  3. Review clauses 6.3, 7.3 and 9.3.2, which UKAS rates as significant, and note where your calibration program is affected.
  4. Ask your certification body when your transition audit will happen and what it wants to see.
  5. Keep calibrations on schedule during the transition. Overdue instruments and missing records can cause findings under either edition.
  6. Keep a short record of your gap review and the changes you made, so you can show it at the transition audit.

When do you have to transition?

The dates come from Global ACI-TECH-3-TR 2029-09-30 (M), which is mandatory for accreditation bodies that have signed the Global ACI arrangement and for the certification bodies they accredit. The transition period is three years.

  • The transition audit can run with a surveillance or recertification audit, or as a special audit. It can be remote if the audit objectives are still met.
  • It reviews the changed requirements, changes to your context and any other changes your system needs. The certification body decides whether extra audit time is needed.
  • If you choose not to transition, your certification ends when the transition period ends, even if the certificate shows a later date.
  • Accreditation bodies can add their own milestones. UKAS, for example, tells certification bodies to stop accepting new applications against the old edition by March 16, 2028.
Key dates for the transition to ISO 9001:2026 under Global ACI-TECH-3-TR 2029-09-30 (M)
DateWhat happens
September 16, 2026ISO 9001:2026 is published.
March 31, 2027Latest date for accreditation bodies to be ready to assess to the new edition.
June 30, 2027Certification bodies submit their transition declarations.
September 30, 2027Accreditation bodies complete their transition decisions.
March 31, 2028From this date, new and initial accredited certifications are issued to ISO 9001:2026 only.
September 30, 2029Certified organizations must have transitioned. Accredited certifications to the 2015 edition are no longer valid after this date.
Tip: A certification body can issue accredited ISO 9001:2026 certificates only after its own accreditation has been transitioned, so ask yours when it expects that to happen.

What about IATF 16949, AS9100 and ISO/IEC 17025?

Several sector schemes are built on ISO 9001. Global ACI names the aviation, space and defense series (AS/EN/JISQ/IA 91XX), TL 9000, IATF 16949, ISO 22163 and ISO 29001. They run their own revisions, so ask your certification body which edition applies to your audits.

For automotive, IATF Stakeholder Communiqué SC-2026-005 (July 2026) plans IATF 16949 Revision 2 for mid-2027 and says the dates are indicative. It also says the end of that transition will align with the end of the ISO 9001 transition. Its five priority topics do not include measuring equipment, so it says nothing about IATF 16949 clause 7.1.5.

ISO/IEC 17025 is a separate standard for laboratory competence, and accreditation bodies still work to ISO/IEC 17025:2017. The revision of ISO 9001 does not change how your calibration supplier is accredited.

What is not publicly confirmed?

A public summary can only go so far, because the standard is sold by ISO and its national members and cannot be reproduced. As of November 2026 these points are not settled by the public sources we checked.

  • The exact 2026 wording of clauses 7.1.5.1 and 7.1.5.2.
  • What changed in clause 7.1.5.2 beyond its title.
  • Whether Annex A says anything specific about measuring equipment.
  • How revised sector standards will treat calibration.
Tip: If your certification body has a clause-by-clause comparison, ask for it. ISO also publishes an overview page and a brochure on using the new edition.

How Axiospec helps with the calibration records

Axiospec is calibration management software. Each instrument has a record with its status, calibrations, certificates and next due date, and reminders go out before it comes due. A calibration can carry test points with as-found and as-left readings, and you pick the reference standard it was done against, so the standard's own record lists the calibrations it was used on.

Any approved record that is a Fail, a Damaged or a Pass with as-found out of tolerance needs an impact written, and those still waiting for one show in Needs attention. An accepted Fail or Damaged puts the instrument in Quarantined until an accepted Pass, Pass with Adjustment or a manager releases it.

Axiospec does not read the standard for you and does not certify anything. The clause wording and the transition stay with you and your certification body.

It is free for up to 50 active instruments. A new workspace starts with a 45-day trial of Professional, with room for 1,500 active instruments. We load your existing records for you at no charge on every plan.

Common questions

Does ISO 9001:2026 change the calibration requirements?
Very little that is publicly known. In the UKAS gap analysis, clause 7.1.5 keeps its number and title, clause 7.1.5.1 is rated no change and clause 7.1.5.2 is rated minor with the new title Traceability of measurement results. The exact wording is in the paid standard, so read it in your own copy.
What is the new title of ISO 9001 clause 7.1.5.2?
In ISO 9001:2026, clause 7.1.5.2 is titled Traceability of measurement results, according to the UKAS gap analysis. In the 2015 edition it was titled Measurement traceability. The clause number did not change.
When do organizations have to transition to ISO 9001:2026?
Under Global ACI-TECH-3-TR 2029-09-30 (M), certified organizations must complete their transition by September 30, 2029. From March 31, 2028, new and initial accredited certifications are issued to the 2026 edition only.
Are ISO 9001:2015 certificates still valid?
Yes, up to the end of the transition. ISO has withdrawn the 2015 edition as a published standard, but accredited certifications to it stay valid until September 30, 2029 at the latest, under Global ACI-TECH-3-TR 2029-09-30 (M).
Do we need to recalibrate equipment because of ISO 9001:2026?
No public source asks for it. Neither the UKAS gap analysis nor the Global ACI list of key changes calls for recalibrating equipment or reissuing certificates because of the new edition. Keep calibrating on your normal intervals.
How does ISO 9001:2026 affect IATF 16949?
IATF 16949 is being revised on its own schedule. IATF Stakeholder Communiqué SC-2026-005 plans Revision 2 for mid-2027, says the dates are indicative and aligns the end of its transition with the end of the ISO 9001 transition.
