EU AI Act, NIST AI RMF, and ISO/IEC 42001: What Each Asks of You

The Core Reality: These three are different kinds of thing. The EU AI Act is a law with obligations that depend on how risky a system is and on your role. The NIST AI Risk Management Framework is voluntary guidance organized around four functions: Govern, Map, Measure, and Manage. ISO/IEC 42001 is a certifiable management-system standard for AI. One well-run AI register and governance process can serve evidence for all three.

Where Teams Get Stuck

Treating each as a separate project triples the work and produces three disconnected binders. The harder issue is that the three do not line up one-to-one: a law classifies systems by risk, a framework describes practices, and a standard describes a management system that an auditor can certify.

How RAMP Handles It

RAMP keeps one AI register and one governance workflow, then maps the same records to each source. The register supports system classification, the requirements document and approvals show the governance practices, and the board briefing and audit package provide the management-system evidence. RAMP prepares the evidence; it does not issue certifications or legal opinions.

The Situation

A company selling into Europe is asked about EU AI Act readiness. A US customer asks which AI risk framework it follows. A procurement team asks whether it is certified to ISO/IEC 42001. The same team receives all three questions in one quarter.

EU AI Act: a law, applied by risk and role

The Act sorts AI systems by risk, from prohibited practices through high-risk systems to those with lighter transparency duties, and it assigns duties differently to providers and to those who deploy a system. It applies in phases, and some dates and details have been under revision, so confirm current application dates with counsel. What you need in every case: to know which systems you have, what each does, and your role for each.

NIST AI RMF: a voluntary framework in four functions

Govern sets policies, roles, and culture. Map establishes context and identifies risks for each system. Measure analyzes and tracks those risks. Manage prioritizes and acts on them. It is widely used as a common language with US customers and is not a certification, so you show alignment through documented practice.

ISO/IEC 42001: a management system you can certify

ISO/IEC 42001:2023 specifies requirements for an AI management system: scope, leadership, risk assessment and treatment, controls, monitoring, and continual improvement, assessed by an accredited certification body. It rewards exactly what a board and register produce: defined roles, recorded decisions, and evidence that the process runs.
The Bottom Line

Start with the register and the two approval gates. Every one of the three sources asks for them in some form.

Frequently asked questions

Is NIST AI RMF mandatory?
No. It is voluntary guidance. Customers, regulators, and contracts may still expect organizations to align with it.
Can a company be certified to ISO/IEC 42001?
Yes. ISO/IEC 42001:2023 is a certifiable AI management-system standard, assessed by an accredited certification body.
Does one AI governance process satisfy the EU AI Act, NIST AI RMF, and ISO 42001?
One register and governance workflow can supply evidence for all three, but they are different in nature, and each still needs its own mapping and, for the EU AI Act, legal review of your role and risk classification.
Leadership Action Item

Build the register and the approval process once, then map them outward. Ask counsel to confirm your EU AI Act role and classification; use the process to produce the evidence.
