Using AMEVSC-08-11e – which was the resulting document from the 8th meeting – as a basis, the proposal from Japan (AMEVSC-09-03e) was discussed.

Japan explained that their concern was that the technical service carrying-out the braking system type-approval would have no choice other than to accept the use of a simulation tool with an old simulation tool validation report regardless of its suitability.

No other changes were made and the secretary undertook to check the document AMEVSC-09-05e for consistency, add a justification and send it to GRRF as an informal document amending GRRF/2012/2 for consideration at the September 2012 GRRF.

The secretary also undertook to create a revision of GRRF/2012/2 which took into account the changes proposed in the informal document.

It was pointed out that the use of the word “may” in the first sentence (“….. amendments to this Regulation, may continue to be used ….”) meant that there was no compulsion on the technical service to accept the validation report and that, therefore, the last sentence in the Japanese proposal was not necessary. To clarify the suitability of the simulation tool for a braking system type-approval with regard to Annex 21, the wording “the relevant technical requirements are fulfilled” was added. This would ensure that a simulation tool with an old validation test report could only be used if it met the requirements of the proposed amendment.

The resultant text is given in document AMEVSC-09-05e.
