7. The expert from France, Chair of the Informal Working Group (IWG) on Behaviour of M2 and M3 vehicles’ general construction in case of Fire Event (BMFE) introduced document GRSG-118-16, containing an overview of proceedings of the 8th and 9th sessions of the IWG on BMFE, the group’s activities and progress in the development of amendments to UN Regulations Nos. 107 and 118, and the schedule for upcoming sessions of the IWG. He invited GRSG experts to provide feedback on questions highlighted in the informal document. The expert also introduced document GRSG-118-02, containing a proposed amendment to UN Regulation No. 107.

8. GRSG considered GRSG-118-02 and requested its submission as an official document for consideration at the October 2020 session of GRSG. The Chair of GRSG invited delegates to submit further comments to be considered for addition to the proposal, if any.

Presentation on the use of simulation tools under type approval and in discussions on the validation of automated driving systems.

5. The expert from France introduced GRVA-04-07 informing on activities in his country concerning the development of a test centre for active safety, New Cars Assessment Programmes (NCAPs) activities, vehicle connectivity and automation.

28. The expert of OICA reported on a study with the aim to determine the inter-dependency between the rolling sound, rolling resistance and the main safety performances by carrying out tests according to regulatory or standard procedures (GRBP-70-25). The expert from OICA pointed out, that given the budget constraints, the study had focused on C1 tyres. The study results indicated a conflict between the rolling sound and safety performances, like wet grip, dry grip and lateral aquaplaning. According to the expert, a low level of rolling sound could not be proven as feasible without compromising other parameters essential for vehicle safety and CO2 emission reduction. He added that a full study report would soon be available. Various experts thanked OICA for the study and indicated they would further consider its results. The Chair invited experts to transmit their comments to OICA, if any.

Presentation on the research paper “Experimental approach for evaluating uncertainties associated to stationary vehicle noise according to ISO 5725”.

Progress report on the effort to improve the behaviour of M₂ and M₃ general construction of buses in case of fire events.

10. The expert from France, chairing the Informal Working Group (IWG) on the behaviour of the general construction of M2 and M3 vehicles in a fire event (BMFE), introduced GRSG-115-07 on the outcome of the recent meetings held in Berlin on 15 June 2018 and in Paris on 10 and 11 September 2018. He reported that IWG had identified mainly the need to strengthen the provisions of (a) UN Regulation No. 118 particularly on the toxicity and opacity of the smoke, its invasion and evacuation and (b) UN Regulation No. 107 on smoke extraction and fire detection systems, taking into account the safety instructions and functionalities of automatic opening of exits, luminous indicators and trajectories. GRSG welcomed the updated information by France on the progress of work and noted that the forthcoming meeting of IWG on BMFE was scheduled to be held in Madrid on 27 and 28 November 2018.

11. GRSG agreed to resume consideration of this subject at its next session.
