  1. Informal document No. GRB-42-10 (42nd GRB, 5 – 7 September 2005 agenda item 1.2.1.) 42. GRB 5.-7. September 2005 Different Scenarios forthe Implementation of theNew Test Method

  2. Content • Scenario I (Proposed by WP. 29) • Scenario II • Scenario III • Alternative Solutions • Conclusions Christian Theis, Referat S 34

  3. Scenario I • ECE-R 51.02 stays as it is and the new test method has to be added. • Vehicles have to be tested according two methods: • For type approval according ECE-R 51.02 • For data collection according the new methods Christian Theis, Referat S 34

  4. Scenario I • Advantages: • The new method is inserted into the regulation (“frozen”) • Experience with the new method • Increase of vehicle data base • Adoption of the new method can be done very quick Christian Theis, Referat S 34

  5. Scenario I • Disadvantages: • Increase of the time delay • Increase of costs for type approval • No benefit for the environment • How can the new data base be used for finding “limit values”? (“worst case testing ↔ different vehicles for ECE-R 51.02 and new test method”) Christian Theis, Referat S 34

  6. Scenario I Time schedule: Christian Theis, Referat S 34

  7. Scenario II • New Series of Amendment ECE-R 51.03 • Content of ECE 51.03 • New test method • New limit values (all vehicle categories) • Test procedure for “Off cycle emission provisions” Christian Theis, Referat S 34

  8. ScenarioII • Advantages: • Benefit for the environment • Costs for testing are minimized Christian Theis, Referat S 34

  9. Scenario II • Disadvantages: • Test procedure for “off cycle emissions” is not available • Data base for HDV needs more measurement results • “Informal Group” needs more time Christian Theis, Referat S 34

  10. Scenario II Time schedule: Christian Theis, Referat S 34

  11. Scenario III • ECE-R 51.02 stays as it is and the new test methodwithlimit values for M1, N1, M2≤ 3500 kg and N2 ≤ 3500 kg have to be inserted • Vehicles of the above mentioned categories have to be tested according two methods and have to fulfil both limit values • Vehicles of other categories have to be tested according ECE-R 51.02 Christian Theis, Referat S 34

  12. Scenario III • Advantages: • Benefit for the environment • The new method is inserted into the regulation (“frozen”) • Experience with the new method for HDV • Increase of vehicle data base for HDV • Adoption of the new method can be done very quick • ECE-R 51.02 becomes “place holder” for “off-cycles” • Proposals for limit values (M1, N1,..) are available Christian Theis, Referat S 34

  13. Scenario III • Disadvantages: • Additional Amendment for HDV is necessary • Costs for type approval Christian Theis, Referat S 34

  14. Scenario III Time schedule: Christian Theis, Referat S 34

  15. Alternative solutions • More stringent limit values in ECE-R 51.02 • Change of tyre selection in ECE-R 51.02 • Modifications of the scenarios • … Christian Theis, Referat S 34

  16. Conclusions • ….. Christian Theis, Referat S 34
