Agenda Item 5.3.
Proposals from China

The representative of France, Japan, OICA and IMMA expressed their views on each modifications of the proposal from China. The positions and the justification are summarized in the table below:

R10 ProvisionsTF OpinionJustification
1.3.(a)OICA, France and Japan do not support the proposal. IMMA can accept the proposal, but will check with experts.OICA: The topic is already covered by present wording of §1.3 (c) in R10.
7.4.2.1.
7.4.2.2.
OICA supports the proposal from China with a change of one item: “the maximum relative voltage change dmax, shall not exceed 6 per cent. Japan and France aligned with the OICA proposal. IMMA has no comment and will check with experts.OICA: Vehicles in charging mode can be considered as “switched manually”, therefore the “6 per cent” value for dmax is the applicable one.
Annex 4, Appendix 1, Figure 1OICA, France and Japan do not support the proposal from China to delete the figure 1. IMMA will check.OICA: It is an additional possibility for L-category vehicles with different requirements for test site than those defined in CISPR12. Therefore the figure shall be kept in R10.
Annex 6, paragraph 4.1.OICA, France, Japan and IMMA do not support the proposal from China.OICA: The table for frequency steps is already defined in ISO 11451-1 3rd edition 2005 and Amd1: 2008 which is referred in R10.04 and R10.05. Furthermore, vehicle manufacturers may choose to perform test with more frequency steps.
Annex 6, paragraph 5.1.2.OICA, Japan, France and IMMA do not support the deletion of the sentence on TLS. The sentence should be kept.TLS is used by some vehicle manufacturers mainly in the [20-30] MHz frequency range.
OICA, Japan, France, IMMA do not support making distinction between vehicle categories.ISO 11451-2 defines the use of 4-field probes method calibration in the [20 or 30 MHz and 2 GHz] frequency band whatever the vehicle category (L,M,N,O).
OICA has a counter proposal: “For TLS one field probe at the vehicle reference point shall be used. For antennas, four field probes at the vehicle reference line shall be used."

These comments have to be transmitted to the Chinese delegates in order to start discussion and potentially building an informal document for next GRE-75
