  1. SGS 4 - 09 GTR-Development for H2- and FC-Vehiclesa TÜV SÜD - opinion

  2. Some Thoughts on1. Approval2. GTR-Development

  3. 1. Approval

  4. One of the most important Rules in Safety Technology: Prevention is better than cure Abteilung:

  5. Someexperiences in the last 5 yearswith CNG- and LPG-vehicles in Europe: • - 6 burstincidents (Saarland-CNG, Recklinghausen-LPG, Emmendingen-LPG, Speyer-LPG, Brescia-CNG, France-CNG) • - reasons: positionof PRD, LPG-tank was filledat a CNG-station, missing PRD, failingsolenoidvalve, toosmallorificeof PRD-ventline • 3 crashincidentswith LPG-vehicles (Rinteln, Dülmen, Thalwil-CH) • Noburstofcontainers Abteilung:

  12. DRAFT STRUCTURE of HFCV-GTR, SGS 3-10, dated 2008-05-15 I. Storage system provisions II. Vehicle fuel system integrity provisions III. Electric safety Abteilung:

  13. components and system requirements? Questions arised during GTR-Discussions: I. Storage system provisions 1. Scope and Purpose 2. Application 3. Definitions 4. General Requirements 5. Performance Requirements 6. Test conditions and procedures 7. Annexes  Which components? Container, valve, PRD, filling device? Functional safety/quality of ECUs? protection against overpressure Potential ignition sources Mechanical protection, … Part I or II? Who is adressed? Component manufacturer or vehicle/system manufacturer? … Documentation? Burst ratios, fire protection, …

  14. Proposal: Part I: basic requirements for accident prevention for system and components I. Storage system provisions 1. Scope and Purpose 2. Application 3. Definitions 4. General Requirements 5. Performance Requirements 6. Test conditions and procedures 7. Annexes  System and component requirements CGH2 and LH2 H2-system excluding propulsion s. or other consumers System, e.g. mechanical, electrical, functional r. Components, e.g. P, T, Material, Media, function, etc. System, e.g. overpressure/temperature, leakage, ignition sources, single failure, monitoring, vehicle integration, shut off strategy Components (container, valve, PRD, filling device) Documentation system Documentation components Abteilung:
