Proposed list of UN Regulations applicable to IWVTA Phase 2 (2018 – 2022).

Presentation of information confirming that there would be no conflict between the draft proposal of minimum reverse-warning requirements and UN R138 on quiet road transport vehicles (audible approaching vehicle warning systems).

Proposal to reconcile UN R138 with UN R51 with regard to maximum sound pressure levels at speeds greater than 20 km/h by clarifying that the 75 dB(A) limit for AVAS under UN R138 concerns only the 0-20 km/h speed range.

Proposal to

1. exempt hybrid vehicles that do not provide valid test results (e.g., internal combustion engine active under test conditions)
2. clarify the text concerning permissible AVAS operating conditions
to differentiate indoor and outdoor facility requirements (e.g., weather station requirement) and
3. update flowcharts in Annex 3 in line with text.
4. add a footnote to the scope to exempt electrified vehicles where the internal combustion engine (ICE) operates under the test conditions
5. clarify the intention of paragraph 6.2.:
   • that AVAS may be operational outside the specified speed ranges (e.g., in the USA where the speed range extends to 30 km/h),
   • align maximum sound with UN R51.03 ASEP, and
   • explicitly specify that the AVAS may function even when the ICE is running
6. clarify under paragraph 6.2.6. that a manufacturer may install an attenuation to enable the system to operate at different sound levels
7. split and clarify indoor and outdoor testing specifications under Annex 3 paragraph 2.2. to account for different needs such as a weather station
8. amend the flowcharts in the Annex 3 Appendix to better reflect the regulation text
9. align the transitional provisions in the 01 series of amendments with the format introduced following Revision 3 of the 1958 Agreement.
