Overview
ISO 20188:2018 - Space systems: Product assurance requirements for commercial satellites provides recommended product assurance (PA) practices tailored to the commercial satellite sector. The standard outlines organizational, technical and procedural expectations to help manufacturers, prime contractors and suppliers deliver reliable, safe and traceable satellite products. It focuses on practical PA and quality assurance measures across design, procurement, manufacturing, testing and delivery phases.
Key topics and technical requirements
ISO 20188:2018 addresses a broad set of product assurance areas important for space systems, including:
- Product assurance management
- PA planning, audits, customer right of access, PA progress reporting and organizational capability.
- Quality assurance (QA) program elements
- QA program requirements, design and manufacturing readiness reviews, in‑process inspection, workmanship standards, non‑conformance control and alert systems.
- Configuration management
- Identification, control, change classification and status accounting for satellite configurations.
- Testing and test control
- Test facilities and equipment, test documentation, test performance monitoring and test reviews.
- Dependability and reliability analyses
- Reliability prediction, parts derating/application reviews, worst case analysis, FMECA, FDIR, fault tree and availability analyses.
- Safety and hazard control
- System safety program, hazard analyses, safety design measures and safety training.
- EEE parts and parts control
- Parts program planning, parts selection, screening, LAT/QCI, destructive physical analysis and traceability (including considerations for space‑qualified vs non‑space‑qualified parts).
- Materials, mechanical parts and special process control
- Policies for material selection, mechanical parts and special manufacturing processes.
- Contamination, ESD and handling
- Electrostatic discharge control, contamination/cleanliness plans, packaging, storage and shipping controls.
- Subcontractor and supply‑chain assurance
- Procurement control, sub‑tier evaluation, surveillance and incoming inspection.
Practical applications - who uses this standard
ISO 20188:2018 is practical for:
- Satellite manufacturers and prime contractors establishing or harmonizing PA programs.
- Component and subsystem suppliers who must meet customer PA expectations.
- Quality, reliability and safety engineers responsible for test plans, FMECA, FDIR and non‑conformance systems.
- Procurement and supply‑chain managers implementing source selection, lot control and traceability.
- Test laboratories and integration teams preparing flight readiness and pre‑shipment reviews.
- Project managers and customer representatives needing a structured PA framework for commercial satellite projects.
Related standards and guidance
ISO 20188 is complementary to other space and parts standards and agency requirements (references to MIL, JAXA and other space‑qualified parts practices appear in the standard). Organizations typically align ISO 20188 with applicable national/agency standards and industry QA practices to ensure compliance across the supply chain.
