ISO 42001 vs Other AI Standards: What’s the Difference?

Artificial Intelligence (AI) is rapidly transforming industries, from healthcare and finance to cybersecurity and manufacturing. However, as AI adoption accelerates, the need for structured governance, risk management, and compliance has never been more critical.

Various AI regulations and standards have emerged globally, but ISO/IEC 42001 stands out as the first AI Management System (AIMS) standard designed to provide a structured framework for organisations developing and using AI.

So how does ISO/IEC 42001 compare to other AI regulations and frameworks like the EU AI Act, NIST AI Risk Management Framework (AI RMF), and OECD AI Principles? Let’s break it down.


What is ISO/IEC 42001?

🔹 ISO/IEC 42001 is the first international standard for AI management systems, developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

🔹 It provides a structured approach to governing AI systems, ensuring that organisations can develop, deploy, and monitor AI responsibly.

🔹 Unlike other AI regulations that focus on policy and ethics, ISO 42001 is a practical implementation framework that helps businesses align AI operations with risk management and compliance best practices.

Key Features of ISO/IEC 42001:

✅ Establishes an AI Management System (AIMS)
✅ Helps businesses mitigate AI-related risks
✅ Ensures transparency, fairness, and compliance in AI operations
✅ Integrates AI governance into existing ISO management systems like ISO 27001 (Information Security)


How ISO/IEC 42001 Compares to Other AI Standards & Regulations

1. ISO/IEC 42001 vs EU AI Act

The EU AI Act is a legal framework that classifies AI systems based on risk levels (e.g., high-risk AI applications in healthcare, law enforcement, and finance). It imposes strict regulatory requirements for high-risk AI systems.

🔹 Key Difference: While the EU AI Act is legally binding in the EU, ISO/IEC 42001 is a voluntary international standard that helps businesses meet compliance requirements globally.

🔹 Who Needs It?

  • EU-based companies developing high-risk AI applications must comply with the EU AI Act.
  • Global businesses seeking structured AI governance should implement ISO 42001.

2. ISO/IEC 42001 vs NIST AI Risk Management Framework (AI RMF)

The NIST AI RMF, developed by the U.S. National Institute of Standards and Technology, is a risk-based AI framework that provides guidelines for trustworthy AI but does not provide a certification or structured management system.

🔹 Key Difference: ISO/IEC 42001 focuses on organisational AI governance, while NIST AI RMF is a broader risk framework without a certification path.

🔹 Who Needs It?

  • Businesses in the U.S. often refer to NIST AI RMF as a best practice guide.
  • Organisations that want a structured AI management system with certification should choose ISO 42001.

3. ISO/IEC 42001 vs OECD AI Principles

The OECD AI Principles, developed by the Organisation for Economic Co-operation and Development, focus on AI ethics, fairness, and accountability rather than operational AI governance.

🔹 Key Difference: ISO/IEC 42001 helps organisations implement practical AI governance, whereas OECD AI Principles focus on ethical guidelines without specific implementation steps.

🔹 Who Needs It?

  • Government policymakers and researchers use the OECD AI Principles for shaping AI policies.
  • Businesses needing certified AI governance frameworks should adopt ISO 42001.

Why Businesses Should Adopt ISO/IEC 42001

With AI regulations tightening worldwide, businesses must take a proactive approach to managing AI risks and compliance. ISO/IEC 42001 offers a structured, certifiable approach that can:

Help organisations comply with AI regulations (EU AI Act, NIST, GDPR)
Improve AI transparency, accountability, and fairness
Reduce AI-related risks and enhance trust in AI systems
Align AI governance with ISO standards like ISO 27001 (Information Security)
