13. Japan presented a proposal for discussion on the sequence of phases (document DHC-09-04). OICA members noted that the duration of the full sequence was extremely long and queried whether pre-conditioning on both High & Extra-High speed phases was necessary. The vice chair queried whether the second Medium speed phase (following hot start Low speed phase) was necessary. It was noted that this might be of value for testing hybrid vehicles, but was unnecessary for conventional vehicles. The vice chair recalled the conclusion of the 7th DHC meeting that OICA, JRC and JARI should develop a proposal for the test sequence during validation 1 and that, whilst the DHC group should make recommendations for test sequence, DTP would need to agree any proposal. It was agreed that alternative proposals for test sequence were welcome. |
