Overview
EN 16602-40-12:2014 is a European Standard focusing on space product assurance through Fault Tree Analysis (FTA). This standard integrates the internationally recognized IEC 61025 methodology into the European Cooperation for Space Standardization (ECSS) system. Its primary purpose is to define the requirements for conducting FTA on space projects, ensuring the analysis aligns with the specific demands and constraints of space systems.
FTA is a systematic, deductive failure analysis technique used to identify and evaluate the causes of system failures. By adopting IEC 61025 within the ECSS framework, this standard establishes a consistent approach to analyze potential faults that could impact spacecraft dependability and safety.
Key Topics
Fault Tree Analysis (FTA) Requirements: EN 16602-40-12:2014 specifies how to perform FTA on space-related projects, emphasizing its application for:
- Catastrophic, critical, or major undesirable events
- Failure mode support analysis
- Accident investigations
Adoption of IEC 61025 Principles: The standard adopts IEC 61025 fully, providing guidelines for:
- Preparation and execution of FTA
- Use of event symbols and fault logic structure
- Identification of failure assumptions and modes
Tailoring Flexibility: As stated in the standard, FTA procedures may be tailored following ECSS-S-ST-00, adapting them to the particular characteristics and constraints of each space project without compromising methodological integrity.
Supplier and Customer Collaboration: The supplier must seek customer agreement on FTA content and allow for customer reviews, ensuring transparency and alignment on analysis depth.
Software Utilization: When employing software tools to conduct FTA, any computer program used must:
- Support the necessary FTA functionalities
- Comply with project-specific requirements for data exchange and tool interoperability
- Note that the standard does not endorse specific proprietary software.
Applications
EN 16602-40-12:2014 is essential for organizations involved in the design, development, and assessment of space systems aiming to guarantee product safety and dependability. Its practical applications include:
Risk Assessment in Space Missions: Identifying root causes of system failures before launch to mitigate risks and increase mission success probability.
Failure Investigation: Serving as a structured approach to analyze accidents or anomalies during spacecraft operation, enabling informed corrective actions.
Requirement Verification: Ensures that safety and reliability goals related to critical failures are analyzed comprehensively and systematically.
Support for Safety Standards Compliance: Facilitates conformity with broader space product assurance standards within the ECSS framework.
By integrating FTA into the early stages of system engineering, project teams can preemptively address potential failure modes, reducing costly design errors and enhancing operational safety.
