ISO 27875:2026 - Re-Entry Risk Management for Uncrewed Spacecraft and Launch Vehicle Orbital Stages

Space systems — Re-entry risk management for uncrewed spacecraft and launch vehicle orbital stages

ISO 27875:2026 presents a globally harmonized framework for assessing, reducing, and managing the risks posed by re-entering spacecraft and launch vehicle upper stages. It addresses both controlled and uncontrolled re-entry scenarios that could endanger people, property, or the environment.

Scope and Application

The standard applies to:

• All uncrewed spacecraft and launch vehicle stages (including interplanetary craft returning to Earth)
• Orbital debris, payloads, and objects separated during launch phase
• Complete re-entry phases from mission planning through to post-re-entry activities, except for craft with wings/control surfaces meant for soft landings

Key Requirements and Methodologies

• Establishment and continuous update of a Re-entry Risk Assessment and Mitigation Plan (RRAMP)
• Quantification of risk using casualty expectation models, population density analysis, and impact footprint calculation
• Implementation of both design-based and operational risk reductions, addressing radioactive, explosive, and hazardous materials as well as human safety
• Adoption of standard processes, modelling tools, and national/international safety thresholds (e.g., maximum expected casualties)
• Specification of roles for safety representatives, design reviews, and approval steps throughout the mission lifecycle
• Requirements for both normal and contingency notification and reporting to authorities

Stakeholder Impact

The requirements engage satellite operators, launch service providers, spacecraft manufacturers, mission designers, and agencies managing flight safety and environmental protection.

Notable Updates & Evolution

• Expansion of risk factors considered (radioactive, chemical, explosive, and floating fragments)
• Integration of statistical methods and modelling for casualty and environmental risk assessment
• Annexes covering demise design best practices and reporting templates for design review

Key highlights:

• Introduces structured RRAMP for ongoing risk management (planning to operation)
• Expands hazard types, including chemical and radioactive fragments
• Sets new benchmarks for post-re-entry activities and regulatory notifications

ISO 1966:2026 - Crimped Joints for Aircraft Electrical Cables

Crimped joints for aircraft electrical cables

ISO 1966:2026 delivers robust specifications and test methodologies for crimped joints used in aircraft electrical systems—covering both insulated and non-insulated types and a variety of conductor materials (copper, copper alloys, aluminium, and aluminium alloys). Good electrical continuity and mechanical robustness in aerospace wiring are critical for flight safety.

Technical Insights

Common Technical Requirements

• Batch-level quality control is emphasized in both rivet manufacturing (EN 6104:2026) and electrical jointing (ISO 1966:2026), relying on thorough inspection, defect categorization, and process validation.
• Statistical Process Control (SPC) and acceptance sampling feature as best practices for continuous improvement and reliability demonstration.
• Comprehensive documentation and traceability, essential for audit trails and post-delivery investigations.
• Environmental and field testing, from salt mist and temperature cycling for electrical joints, to trajectory modelling and population density analysis for re-entry risk.

Implementation Best Practices

1. Integrate Requirements Early: Engage design, quality, and procurement teams at project start to embed standards into technical requirements and acceptance criteria.
2. Tool and Process Qualification: Validate tooling, measurement systems, and operator training before commencing production.
3. Supplier Quality Audits: Update audit checklists to include new standard requirements. Leverage third-party certification where necessary.
4. Continuous Training: Maintain ongoing training programs for manufacturing, inspection, and risk management roles.

Testing and Certification

• For structural and electrical components, align internal inspection and product release procedures with specified tests (e.g., tensile, voltage-drop, environmental exposures).
