The ISO 42001 certification process

You go through six steps from decision to certificate. Count on nine to eighteen months, depending on your starting position and AI complexity.

The six steps to certification

  1. Determine scope - Which AI systems, processes and departments are covered by the AIMS? If necessary, start with your most important AI applications.
  2. AI inventory and risk analysis - Take an overview of all AI systems and identify the risks. This is the heart of ISO 42001.
  3. Set up AIMS - Implement controls, establish policies, train employees, and document processes.
  4. Complete Evidence Period - Work under your AIMS for a minimum of three months. Auditors want proof that the system works in practice.
  5. Internal audit and management review - Verify that everything is working and have management formally assess the AIMS.
  6. External audit - The certification body carries out the audit in two phases. If successful you will receive the certificate.

Who does what?

You

AI inventory, risk analysis, setting up AIMS, internal audits

IT/Data team

Documenting AI systems, technical measures

Consultant (optional)

Guidance, gap analysis, templates, training

Certification body

Perform audit, issue certificate

Accreditation body

Checks the certification body (the Dutch body, UKAS, etc.)

Good to know: A consultant is not mandatory. Organisations with experienced IT and compliance people can do it themselves. However, guidance can speed up the process.

Preparation for ISO 42001

Good preparation is half the battle. Most of the time is spent on the AI ​​inventory and setting up your AIMS, not on the audit itself.

What do you need to arrange internally?

Then follow these steps:

  • Appoint project leader - Someone with a mandate, AI knowledge and time to spare
  • Create AI inventory - What AI systems do you have? What are they used for?
  • Determine scope - Which systems and processes are covered by the AIMS?
  • Perform risk analysis - Identify risks per AI system
  • Implement measures - Technical and organizational, based on the risk analysis
  • Create awareness - Train employees on responsible AI use
  • Start proof period - Work for at least three months according to the AIMS

What documentation is needed?

The standard requires at least:

AI Policy

Your vision and goals for responsible AI use

Scope of the AIMS

Which AI systems and processes are being certified

AI inventory

Overview of all AI systems with classification

Risk analysis and treatment plan

Identified risks and chosen measures

SoA

Statement of Applicability

Which controls you apply and which you do not, with substantiation

Data governance documentation

How to handle data for AI systems

Process descriptions

Lifecycle of AI systems

No need for a thick manual. Many organisations work with a digital system or compact documents. The form is free, as long as it is current and accessible.

Three common mistakes

Mistake 2: Paper tiger

Your documents must correspond with practice. If you write down that you evaluate AI risks monthly, you really should do that. Auditors ask for evidence.

Mistake 3: Starting the proof period too late

You must have worked under your AIMS for at least three months before the external audit can take place. Plan this, otherwise your certification date will be postponed.

Questions about ISO 42001

What is ISO 42001?

ISO 42001 is the international standard for AI management systems (AIMS). It helps organisations develop, implement and use artificial intelligence responsibly. The certificate shows that you manage AI risks systematically.

What does ISO 42001 certification cost?

For an SME (10-50 employees), ISO 42001 certification usually costs €15,000 to €35,000 in the first year, including support. After that you pay €3,000 to €7,000 a year for surveillance audits. The exact price depends on your company size and AI complexity.

How long does ISO 42001 certification take?

On average nine to eighteen months for most organisations. If you already have a working management system (such as ISO 9001 or ISO 27001), it can be done in six to nine months. The audit itself takes two to five days.

Can I switch to another certification body?

Yes, you can switch at any time. Your new certification body takes over your file and plans a transfer audit. Your certificate remains valid during the switch.

Is ISO 42001 mandatory?

No, ISO 42001 is formally voluntary. But more and more clients, insurers and tenders require it. For high-risk AI under the EU AI Act a quality management system is mandatory, and ISO 42001 can help meet that requirement.

Does ISO 42001 help with the EU AI Act?

Yes. ISO 42001 and the EU AI Act overlap by 40-50%. The standard helps you meet requirements for risk management, data governance and documentation. It is no guarantee of full compliance, but it covers a large part of the requirements.

Which certification bodies are accredited for ISO 42001?

In the Netherlands, DNV and BSI have held Dutch accreditation for ISO 42001 since January 2025. Other certification bodies such as Kiwa and TÜV also offer it, but are still working on their Dutch accreditation.
