Overview
ISO 14621-1:2019 - Space systems - Electrical, electronic and electromechanical (EEE) parts - Part 1: Parts management provides a baseline framework for establishing an EEE parts management programme for space systems. Written in general terms, it guides organizations in developing, implementing, validating, and evaluating policies and processes that manage electrical, electronic, electromechanical and electro‑optical parts across the programme life cycle. The standard supports a system‑level approach to risk management, parts selection, and long‑term sustainment.
Key topics
The standard addresses practical EEE parts management elements, including:
- EEE parts management process: design process, design margin, life‑cycle cost considerations, technical support, and systems‑engineering integration.
- Parts selection: guidance and a checklist (Annex B) to select parts appropriate to mission requirements and environments.
- Obsolescence management: early assessment of part availability risk and mitigation strategies to minimize programme disruption (DMSMS).
- Supplier management: requirements for vendor verification, management processes, information control and internal controls; includes a supplier/subcontractor checklist (Annex C).
- Technology insertion strategy: planning for new and emerging technologies to reduce obsolescence and manage risk across concept, production, and field support phases.
- Shared data and community alerts: mechanisms for peer‑to‑peer problem sharing and shared databases (Annex D) to improve industry situational awareness.
- Process control & validation: documenting, approving, and validating approaches for controlling EEE parts risks.
- Training and systems engineering: emphasis on integrating parts engineering into all life‑cycle phases and maintaining trained personnel.
- Informative annexes: Radiation effects (Annex A) and practical checklists support implementation.
Applications
ISO 14621-1:2019 is used to:
- Develop or tailor an EEE parts management programme for satellites, launch vehicles, payloads and ground support hardware.
- Inform procurement, risk assessments, and supplier evaluation for space‑flight hardware.
- Guide parts engineers, systems engineers and reliability teams in selecting parts and planning technology insertion.
- Set baseline contractual language for primes, subcontractors and suppliers concerning parts management expectations.
Who should use it
- Spacecraft manufacturers, prime contractors and subsystem suppliers
- Systems, reliability and parts engineers
- Procurement, quality assurance and supply‑chain managers
- Programme managers responsible for life‑cycle cost, sustainment and obsolescence risk
