ISO 10012:2026 Readiness: 25 Questions Before Stage 1

Your biggest customer’s supplier-development engineer sends a one-line email: "Is your measurement management system ISO 10012-aligned, and do you intend to certify?" You run 1,400 instruments across three plants. Confirmation records live in a calibration spreadsheet that two people trust and nobody else can edit, plus a binder of certificates in the metrology room. The honest answer is "probably, mostly". Before you write that down, or phone a certification body, it is worth finding out what "mostly" means.

This article gives you a readiness questionnaire to do that. It has 25 questions grouped under the clause headings of ISO 10012:2026, and every answer has to point to a named record. A question you can only answer with "we do that" counts as unanswered.

First, what is actually confirmed about ISO 10012:2026

Precision matters here, because a good deal of what circulates about this standard is wrong.

Verified from catalogue and standards-body sources:

• ISO 10012:2026, Quality management — Requirements for measurement management systems, was published on 12 February 2026 as the second edition. It replaces ISO 10012:2003 and is owned by ISO/TC 176/SC 3.
• It is restructured to the harmonized structure, clauses 4 to 10: context, leadership, planning, support, operation, performance evaluation, improvement.
• BSI describes it as moving from a general guide to a standard that is auditable and certifiable, and applicable to production environments, not only laboratories. Certification remains optional.
• It excludes calibration and testing service providers covered by ISO/IEC 17025, and it does not add requirements to that standard.
• Its emphasis areas, as described consistently by commentators, are measurement risk, interval optimisation, measurement uncertainty and decision rules.

Not verified, so do not plan around it:

• We have not found an accreditation body or certification body publicly offering accredited ISO 10012:2026 certification. A standard that is "certifiable" by design is not the same thing as an accredited scheme your CB can issue a certificate under. Ask your CB directly, and check its accreditation scope.
• Figures you may have seen quoted, such as a count of "shall" statements, do not appear in any primary source we could find.

One further change: IAF and ILAC now operate as the Global Accreditation Cooperation, from 1 January 2026, and existing recognition arrangements remain valid during the transition. If a CB’s answer about accreditation sounds vague, that transition may be part of the reason.

Why the questionnaire works on records, not intentions

In a typical certification audit, Stage 1 is largely a review of the documentation. The auditor uses it to decide whether you are ready for Stage 2, where they sample how the system actually runs. Stage 1 findings usually come from one pattern: the procedure states something, and no record shows it happened.

For that reason, each question below has a column for the record that answers it. If you cannot name the record, leave the question open, even if the practice exists on the shop floor. The questionnaire also does not quote clause text. It uses the harmonized-structure headings as a frame, so you need the purchased standard beside you to check each question against its actual wording.

The 25-question readiness questionnaire

Clause 4 — Context

| # | Question | Record that answers it |
|—|—|—|
| 1 | Is the MMS scope defined, including which sites, product lines and measurement processes it covers? | Scope statement, controlled document |
| 2 | Have you identified customer and regulatory measurement requirements (e.g. IATF 16949 customer-specific requirements, AS9100 flow-downs)? | Requirements register |
| 3 | If you hold ISO/IEC 17025 for an internal lab, is the boundary between that lab and the MMS stated? | Scope note with interface description |

Clause 5 — Leadership

| # | Question | Record that answers it |
|—|—|—|
| 4 | Is there a metrological function with named authority, not just a job title? | Appointment record, organisation chart |
| 5 | Has top management approved a policy covering measurement? | Signed policy, revision history |
| 6 | Can someone other than the metrology lead explain the policy? | Interview notes from your internal audit |

Clause 6 — Planning

| # | Question | Record that answers it |
|—|—|—|
| 7 | Have measurement risks been assessed per measurement process, not per instrument? | Measurement risk assessment |
| 8 | Are there measurable MMS objectives, for example in-tolerance rate at due date? | Objectives sheet with current values |
| 9 | Is there a documented basis for setting and changing confirmation intervals? | Interval policy plus change log |
| 10 | Is a decision rule defined for conformity statements? | Procedure section, referenced in work instructions |

Clause 7 — Support

| # | Question | Record that answers it |
|—|—|—|
| 11 | Is every instrument in scope registered with a unique ID, location and owner? | Instrument register export |
| 12 | Is traceability shown for each calibration, to national or international standards? | Certificates linked to each instrument |
| 13 | Are competence requirements defined for the people who perform confirmation? | Training matrix, competence evidence |
| 14 | Are environmental conditions controlled and recorded where they affect results? | Temperature and humidity logs |
| 15 | Are MMS documents and records controlled, with retention defined? | Document control index |

Clause 8 — Operation

| # | Question | Record that answers it |
|—|—|—|
| 16 | Does each confirmation compare the result against your metrological requirement, not only against the lab’s statement of conformity? | Confirmation record with MPE and decision |
| 17 | Are as-found values recorded before any adjustment? | As-found/as-left record |
| 18 | Are calibration procedures controlled and applied consistently across instruments of the same type? | Procedure templates with version |
| 19 | Is use of an overdue or non-confirmed instrument physically or procedurally prevented? | Blocking configuration plus exception log |
| 20 | Do you know who held an instrument, and where, during any given period? | Check-out and possession history |
| 21 | Are measurement processes themselves controlled, for example through MSA, intermediate checks and control charts? | MSA studies, check records |
| 22 | When an instrument is found out of tolerance, is the impact on product assessed and closed out? | OOT impact record linked to affected lots |

Clauses 9 and 10 — Performance evaluation and improvement

| # | Question | Record that answers it |
|—|—|—|
| 23 | Has an internal audit covered the full MMS against ISO 10012:2026, not only 7.1.5? | Audit programme and report |
| 24 | Has management review considered MMS performance data? | Review minutes with inputs |
| 25 | Are MMS nonconformities tracked to verified effectiveness? | Corrective action log |

Scoring it honestly: a worked example

Take the supplier from the opening. For each question, score 2 if the named record exists and is current, 1 if the practice exists but the record is partial or held informally, and 0 if neither exists.

A realistic first pass might look like this:

• Questions 11, 12, 15 and 17 score 2. The spreadsheet and the binder do cover these.
• Questions 18, 19, 20 and 22 score 1. Procedures exist as PDFs of uncertain version, blocking depends on a sticker and a supervisor’s memory, nobody can say who held torque wrench TW-0412 last March, and OOT impact is assessed in emails.
• Questions 7, 8, 9 and 10 score 0. Intervals were inherited from the 2003-era system, and the decision rule is implicit.

That puts the supplier at around 30 out of 50. The pattern behind the score is more useful than the score itself. The zeros sit in planning, which is where the 2026 edition puts its emphasis. The ones sit in operational records, where a spreadsheet stops being enough once an auditor starts sampling across plants. A CB pre-assessment would probably find the same thing, only more expensively.

The objection: "We hold IATF 16949. Isn’t this already covered?"

Partly. ISO 9001 7.1.5 and IATF 16949 7.1.5.x already require traceable calibration, records, and action when equipment is found unfit. Most of questions 11, 12, 17 and 22 will be answered by the evidence you hold today. What they do not ask for in the same depth is a management system for measurement: risk assessed per measurement process, a justified interval policy, defined decision rules, and leadership ownership. Questions 4 to 10 are where IATF-certified plants usually score lowest. The questionnaire is designed to show you that gap rather than assume it.

The reverse objection also comes up: "this is a lot of paperwork for an optional certificate." That is true. If no customer asks and no CB can yet offer you an accredited certificate, use the questionnaire as a self-assessment for World Quality Day or for management review, and stop there. Its value does not depend on certifying.

Where PrüfDesk fits, and where it does not

PrüfDesk covers the records layer behind questions 11, 12, 15 and 17 to 20, and supports 22:

• an instrument register with auto-calculated due dates
• pass/fail confirmation records with as-found/as-left values and attached certificates
• reusable procedure templates that can be overridden per unit
• configurable overdue blocking, either a hard block or a soft warning
• check-out and allocation tracking with a full possession audit trail
• audit-ready PDF reports

All plans include unlimited users. Starter is €49/month for 250 assets, Professional €129/month for 1,000, and Enterprise €299/month for unlimited assets.

It does not cover everything. PrüfDesk does not write your risk assessment, set your decision rule, compute uncertainty budgets, run MSA studies or automate calibration procedures. It is not a complete MMS or QMS, and it does not certify you; only an accredited CB can, once a scheme exists. Questions 1 to 10 and 23 to 25 remain your organisation’s work.

Before you call the certification body

Run the questionnaire with the metrology lead and one person from production. Write the record name, or "none", against each question. Then ask your CB three things: whether it offers ISO 10012:2026 certification, whether that certification is accredited and under which scope, and what it expects to see at Stage 1.
