ISO/IEC 42005:2025
Information technology — Artificial intelligence (AI) — AI system impact assessment
Standard Introduction
ISO/IEC 42005:2025 provides guidance for assessing how an artificial intelligence system and its foreseeable applications may affect individuals, groups, and society. It helps organizations define when to assess impacts and how to identify, evaluate, document, and revisit them across the AI system lifecycle.
The standard applies to organizations developing, providing, or using AI systems regardless of size or sector. It complements ISO/IEC 42001 and ISO/IEC 23894 by turning human and societal impact analysis into a repeatable governance process, but it is guidance rather than a standalone certification standard or substitute for legal analysis.
Human and Societal Impact
Focuses the assessment on how an AI system and its foreseeable uses can affect individuals, groups, and society, including both beneficial and adverse outcomes.
Lifecycle Assessment
Supports impact assessment from design and development through deployment and post-deployment monitoring, with reassessment when the system or its context changes.
Governance Integration
Provides a repeatable impact-assessment process that can feed an organization's AI risk management and ISO/IEC 42001 artificial intelligence management system.
list_alt AI Impact Assessment Focus Areas
- Assessment purpose and decision context
- AI system and foreseeable-use boundaries
- Affected individuals, groups, and societal stakeholders
- Potential beneficial and adverse impacts
- Impact evaluation criteria and prioritization
- Treatment decisions, owners, and documented evidence
- Lifecycle monitoring, triggers, and reassessment
Who Needs to Comply?
Organizations developing, providing, procuring, deploying, or using AI systems that need a consistent way to assess and document effects on people and society. It is relevant across sectors and organization sizes, particularly where AI influences access, safety, rights, opportunities, or important decisions.
Key Requirements
Set Assessment Triggers
Define when an AI system impact assessment is required, who approves it, and which lifecycle events or material changes require reassessment.
Define System and Use Context
Document the AI system, intended and foreseeable uses, lifecycle stage, operating environment, dependencies, limitations, and relevant decisions.
Identify Affected Stakeholders
Determine which individuals, groups, communities, customers, workers, or other societal stakeholders may experience benefits or adverse effects.
Evaluate and Address Impacts
Use consistent criteria to analyse potential impacts, prioritize concerns, select actions, assign owners, and record accepted residual impacts.
Document, Monitor, and Reassess
Maintain traceable assessment records and refresh them after deployment, incidents, stakeholder feedback, performance changes, or changes in use and context.
Implementation Roadmap
Set scope and assessment triggers
Define which AI systems and decisions require an impact assessment, the accountable owner, approval path, assessment timing, and the changes or incidents that trigger reassessment.
Map context and stakeholders
Describe the system, intended and foreseeable uses, lifecycle stage, operating environment, dependencies, and limitations. Identify individuals, groups, and societal stakeholders who may be affected.
Evaluate impacts and decide actions
Identify beneficial and adverse impacts, apply documented evaluation criteria, prioritize concerns, select treatment or design actions, assign owners, and record decisions and residual impacts.
Monitor and reassess
Track deployment evidence, performance, incidents, complaints, stakeholder feedback, and contextual change. Update the assessment and related governance records when a trigger occurs.

ISO/IEC 42005 Compared with Related AI Standards
These standards address different layers of AI governance and are often used together.
| Standard | Primary purpose | Best used for | Certification role |
|---|---|---|---|
| ISO/IEC 42005:2025 | AI system impact assessment | Effects on individuals, groups, and society across the lifecycle | Guidance; not standalone certifiable |
| ISO/IEC 42001:2023 | AI management system | Organization-wide policies, processes, responsibilities, and continual improvement | Certifiable management-system standard |
| ISO/IEC 23894:2023 | AI risk management | Integrating AI-specific risks into organizational risk management | Guidance; not standalone certifiable |
Common Misconceptions
An AI impact assessment is a one-time pre-launch document.
Impact can change with data, models, users, deployment context, scale, or foreseeable use. The assessment process should define monitoring and reassessment triggers across the lifecycle.
Only AI developers need to assess impacts.
The standard is intended for organizations developing, providing, or using AI systems. A deployer can create new impacts through its purpose, users, data, workflow, or operating context.
ISO/IEC 42005 certification proves an AI system is responsible.
ISO/IEC 42005 is guidance and is not a standalone certification standard. Its value is a consistent, documented assessment process and better-informed governance decisions.
Completing the standard automatically satisfies every AI law.
The process can support compliance evidence, but legal duties vary by jurisdiction, sector, system role, and use case and must be mapped separately.
Penalties & Enforcement
ISO/IEC 42005:2025 is a voluntary guidance standard and does not create direct legal penalties or a standalone certification. Its assessment process can support evidence needed for laws, contracts, procurement reviews, and AI governance programs, whose consequences must be evaluated separately.
Frequently Asked Questions
What is ISO/IEC 42005:2025?
expand_more
ISO/IEC 42005:2025 is an international guidance standard for assessing and documenting how an AI system and its foreseeable applications may affect individuals, groups, and society across the AI system lifecycle.
Who should use ISO/IEC 42005?
expand_more
It is intended for organizations that develop, provide, or use AI systems and applies regardless of organization size, type, or sector. Procurement and deployment teams can use it as well as system developers.
Can an organization be certified to ISO/IEC 42005?
expand_more
ISO/IEC 42005 is a guidance standard, not a standalone certifiable management-system standard. ISO/IEC 42001 is the certifiable AI management-system standard; ISO/IEC 42005 can support its impact-assessment process and evidence.
When should an AI impact assessment be performed?
expand_more
The assessment should be considered throughout the AI system lifecycle, from design and development through deployment and post-deployment monitoring, and updated when changes in the system, use, stakeholders, evidence, or context could alter impacts.
Does ISO/IEC 42005 prove compliance with AI laws?
expand_more
No. It provides a consistent assessment method but does not replace jurisdiction-specific legal analysis. Organizations must separately map the assessment to applicable duties such as fundamental-rights, privacy, safety, employment, consumer-protection, or sector rules.
