On-site participation included the OICA delegation, the representatives from France (Mr. Pardo and Mr. Blanc), and representatives from Japan (Mr. Nojima, Mr. Itoh and Mr. Tsukahara). Part of the OICA delegation also participated by teleconference. The representatives from the Russian Federation (Mr. Sergey Vylegzhanin, Ms. Ekaterina Laguzina, and Mr. Ivan Vinogradov) joined at the end of the meeting by teleconference. The representative of IMMA (Daniela Leveratto) joined by teleconference as well, in order to discuss specifically the proposal from China (GRE/2015/36).

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 Provisions | TF Opinion | Justification |
|---|---|---|
| 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 1 | OICA, 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
23. The expert from the Russian Federation introduced amendment proposals on the electromagnetic compatibility (EMC) of trolleybuses (GRE-74-12) with the intention to replace ECE/TRANS/WP.29/GRE/2014/41. The expert from Belgium commented on these proposals. The expert from China proposed a set of amendments to different provisions of Regulation No.10 (ECE/TRANS/WP.29/GRE/2015/36). This proposal received preliminary comments from Finland. Various GRE experts pointed out that, before taking a position on the Chinese and Russian proposals, they had to consult national EMC experts who do not normally attend GRE sessions.
24. To make further progress on the above proposals, GRE decided to create a task force (TF EMC) and invited GRE participants and experts on EMC to take part in this work. OICA volunteered to act as secretary of the task force. GRE agreed that TF EMC should start its activities as soon as possible to address the electromagnetic compatibility of trolleybuses.
