ISO 45001 revision: where it stands and what it means for certificates

Key takeaways

  1. 1ISO publishes the new edition. Until then there is no transition, no transition period and no end date.
  2. 2Global ACI issues transition requirements. Global ACI (formerly IAF) issues a transition requirements document for the new edition. It is mandatory for accreditation bodies and accredited certification bodies, and it sets the dates. For ISO 9001:2026 the transition ends on 30 September 2029; for ISO 14001:2026, on 30 April 2029. The dates for any new edition of ISO 45001 would be set in its own document.
  3. 3Accreditation bodies transition the certification bodies. Each accreditation body completes its transition decisions on the certification bodies it accredits by a date the document sets. Accredited certificates to the new edition follow that decision.
  4. 4Certified organizations transition at an audit before the end date. This can be a surveillance audit, a recertification audit or a special transition audit. The audit reviews, at a minimum, the changed requirements, changes to the organization's context and the need for any other changes to the management system. The certification body decides whether extra audit time is needed.

ISO 45001:2018, with Amendment 1:2024, is the current edition of the standard for occupational health and safety management systems. Every accredited ISO 45001 certificate today is issued against it. ISO is revising the standard, but no new edition has been published, and until one is, nothing changes for a certified organization.

Where the revision stands

On 18 October 2026, iso.org lists ISO 45001:2018 at stage 90.92, "International Standard to be revised". The same page lists the next version, ISO/DIS 45001, as under development. The ISO/DIS 45001 page shows stage 40.60, "Close of voting", for a draft listed as edition 2. The work sits with ISO/TC 283, Occupational health and safety management, which has a working group for the revision of ISO 45001.

A DIS is a Draft International Standard. Stage 40 is the enquiry stage, when ISO members vote on the draft. ISO's harmonized stage codes set out what can follow the close of voting: the draft is approved to go forward as a Final Draft International Standard, a new DIS ballot is held, the draft is referred back to the committee, or the project is cancelled. A standard is published at stage 60.60.

Two things follow. The draft text can still change. And CAS does not audit or certify against a draft. ISO/IEC 17021-1 §8.2.2 e) requires every certificate to identify the standard used for the audit, including its issue status, and for CAS that is always a published edition.

The edition in force

ISO 45001:2018 is the first edition, published in March 2018. Amendment 1:2024, "Climate action changes", was published in February 2024. It added a requirement to clause 4.1, that the organization shall determine whether climate change is a relevant issue, and a note to clause 4.2, that relevant interested parties can have requirements related to climate change.

An amendment takes effect on publication and has no transition period. Those two additions already apply to every certified organization, and certificates still reference ISO 45001:2018.

How a revision turns into a transition

When a new edition of a management system standard is published, the route to new certificates has four steps. It is the route set for ISO 9001:2026 and ISO 14001:2026, and only the first step is in ISO's hands.

  • ISO publishes the new edition. Until then there is no transition, no transition period and no end date.
  • Global ACI issues transition requirements. Global ACI (formerly IAF) issues a transition requirements document for the new edition. It is mandatory for accreditation bodies and accredited certification bodies, and it sets the dates. For ISO 9001:2026 the transition ends on 30 September 2029; for ISO 14001:2026, on 30 April 2029. The dates for any new edition of ISO 45001 would be set in its own document.
  • Accreditation bodies transition the certification bodies. Each accreditation body completes its transition decisions on the certification bodies it accredits by a date the document sets. Accredited certificates to the new edition follow that decision.
  • Certified organizations transition at an audit before the end date. This can be a surveillance audit, a recertification audit or a special transition audit. The audit reviews, at a minimum, the changed requirements, changes to the organization's context and the need for any other changes to the management system. The certification body decides whether extra audit time is needed.

The transition documents for ISO 9001:2026 and ISO 14001:2026 also set a date after which new certifications are issued only to the new edition. After the end date, certificates to the old edition are no longer valid, even where the printed expiry date is later.

What does not change today

  • ISO 45001:2018 certificates run on their normal certification cycle. No transition end date applies to them.
  • Surveillance and recertification audits continue against ISO 45001:2018 including Amendment 1:2024.
  • No transition audit can be planned yet, because there are no transition requirements to plan it against.

CAS's position today

CAS is accredited by EGAC for ISO 45001, and ISO 45001 certificates fall within EGAC's IAF MLA scope. CAS audits and certifies to ISO 45001:2018 including Amendment 1:2024.

ISO/IEC 17021-1 §8.5.2 requires a certification body to give its certified clients due notice of any changes to its requirements for certification. When a new edition is published and its transition requirements exist, CAS will publish the transition dates on this site and contact each certified client to plan its transition audit.

What this means for you

If you are certified to ISO 45001:2018: your certificate is valid on its normal cycle, and no transition deadline exists today. The clause 4.1 climate change determination already applies.

If you are planning first certification: certification is to ISO 45001:2018 including Amendment 1:2024. If a new edition is published during your cycle, its transition requirements will set when your certificate has to move.

If you are a buyer: a supplier's accredited ISO 45001:2018 certificate is not affected by the revision until a transition end date exists, and none exists today.

This is generic information about the requirement, not advice on any particular management system.

CAS — An EGAC accredited MS certification body No. 012418. Accredited scope: ISO 9001, ISO 14001, ISO 45001, ISO 22000, ISO 50001 and ISO 22301. Certificates accredited for ISO 9001, 14001, 45001, 22000 and 50001 fall within EGAC's IAF MLA scope; ISO 22301 is accredited by EGAC and sits outside that scope.
