ISO 27025:2023

Overview - ISO 27025:2023 (Space systems product QA)

ISO 27025:2023, "Space systems - Programme management - Product quality assurance requirements," defines product quality assurance (QA) requirements for space projects across the full lifecycle - from mission definition, design, development and production through operations and disposal. The standard is the second edition (2023) and is applicable to customer–supplier relationships for space products as agreed by both parties. It provides a programme-level framework for establishing and implementing QA programmes tailored to space systems.

Key topics and technical requirements

ISO 27025 organizes QA requirements by programme and technical areas. Major topics include:

• QA programme management: establishment of QA programmes, organisational roles, QA programme plans, status reporting, training/certification, audits and QA involvement in configuration management and critical items control.
• General QA requirements: document/data control, records, stamp control, traceability (identification and data retrieval), metrology and calibration, nonconformity control systems and an alert system for reporting and processing issues.
• Design and verification: design planning, interfaces, design rules (producibility, repeatability, inspectability/testability, operability), standards/procedures, verification methods, design reviews, qualification and design change control.
• Procurement QA: supplier/source selection and records, procurement documentation and review, supplier surveillance (including lower-tier suppliers), receiving inspection and control of customer-furnished items.
• Manufacturing, assembly and integration: planning and readiness reviews, control of processes (including critical processes and statistical process control), workmanship standards, materials/parts control (sensitive items, marking), equipment and tooling control, cleanliness and contamination control.

These topics reflect the standard’s emphasis on traceability, rigorous verification, supplier oversight, and lifecycle QA controls that are essential for space system reliability and safety.

Practical applications

ISO 27025 is used to:

• Develop and implement product QA programmes for satellites, launch vehicles, payloads and ground-segment hardware.
• Define contractual QA expectations between prime contractors, subsystem suppliers and customers.
• Guide procurement, incoming inspection, manufacturing control, integration and pre-launch verification activities.
• Support configuration management, anomaly reporting (alerts) and nonconformity remediation across mission phases.

Who should use this standard

• Space agency programme managers and product assurance (PA) engineers
• Prime contractors, subsystem integrators and tiered suppliers
• Quality managers, procurement officers and manufacturing engineers
• Systems engineers responsible for design verification and configuration control
