ISO 22163:2023

Overview

ISO 22163:2023 specifies requirements for a Railway Quality Management System (RQMS) by applying ISO 9001:2015 plus additional, railway‑specific requirements. It is intended for any organization across the railway supply chain that needs to consistently deliver products and services meeting customer, statutory and regulatory requirements, while enhancing customer satisfaction through continual improvement. The standard emphasizes defect prevention, product quality and safety, and sustained improvement throughout the supply chain.

Key topics and technical requirements

ISO 22163:2023 expands ISO 9001:2015 with sector‑specific guidance. Major topics covered include:

• Context of the organization: understanding internal/external factors and interested parties relevant to railway quality.
• Leadership and policy: customer focus, defined quality policy and organizational roles.
• Risk and business continuity planning: actions addressing risks, opportunities and continuity for railway operations.
• Quality objectives and planning: measurable targets for product quality and safety.
• Resources and competence: people, infrastructure, monitoring and organizational knowledge required for railway products and services.
• Operational control: tender and project management, configuration and change control, production and service provision.
• Supply chain and external providers: selection, control and information for suppliers across the railway sector.
• Design and development: inputs, controls, outputs and management of design changes.
• Verification and inspection: first article inspection, release of products/services, control of nonconforming outputs.
• Reliability, availability, maintainability, safety (RAMS) and life‑cycle costing considerations.
• Obsolescence management: managing end‑of‑life and replacement aspects.
• Performance evaluation: monitoring, customer satisfaction, internal audits, management review and continual improvement.

Practical applications - who uses it and why

ISO 22163:2023 is used by:

• OEMs and component suppliers in the railway sector
• System integrators, maintenance and overhaul providers
• Infrastructure managers and operators
• Procurement and quality managers overseeing railway supply chains
• Certification bodies auditing railway quality systems

Benefits and practical uses:

• Establish a single RQMS framework aligned with ISO 9001:2015 and railway needs
• Improve product safety, reliability and supply‑chain traceability
• Reduce defects, rework and lifecycle costs through preventive controls
• Demonstrate compliance with customer, statutory and regulatory requirements
• Support tenders, project management and supplier qualification across global railway projects
