Proposal to clarify the possibility to install side-facing seats in buses of category M2 and M3 of classes A and I.

Proposal to align the provisions of the 03 series of amendments to UN R24 with UN R85. Other amendments are proposed in order to bring the format of UN R24 up to date.

Proposal to cease new CRS approvals under UN Regulation No. 44 as of 1 September 2020, including amended transitional provisions.

Proposal to amend UN R64 in line with the introduction of the “extended mobility tyre” into UN R30 (see document WP.29/2019/50).

Proposal to clarify requirements of the optical signal for a CSF intervention to ensure sufficient flashing tell-tale visibility for the driver, to specify the duration of such ACSF signals, to ensure a safe hierarchy of signals (e.g., ESF over CSF) by priority, to clarify that deactivation when departing an ODD means the “off mode”, and to add a cross-reference pointing to paragraphs that define cases of manual and automatic deactivation.

Proposal to

1. clarify the relationship between approval levels, reference fuels and PN limits for PI vehicles and to modify the calculation formulae for determination of evaporative emissions in accordance with changes already agreed in UN GTR No. 19
2. correct errors in Working Paper 2019.08
3. expand 2019.08 to clarify the special provisions, and
4. resolve a contradiction in requirements concerning the provision of SCR reagent consumption data via the serial port of the standard diagnostic connector.

Proposal to reduce testing burdens by introducing an alternative test method to “decrease the charge air cooler outlet temperature by the same amount that the ambient conditions for the vehicle test varied from the standard temperature.” This aligns with SAE J1349, “9.3 Application of Vehicle Transient Data to Net Power Test.”

Proposal to align the text in Annex 7 with UN R78 and to insert the reference to the L₆ and L₇ vehicle categories to respond to requests from the industry for type approval for the replacement brake lining assembly for these vehicles.

Proposal to align UN R115 with the GTR No. 15 WLTC test cycle.

Proposal to

1. introduce new and modified labeling and to clarify packaging information to distinguish between forward-facing-only, rear-facing-only, and convertible CRS in order to reduce the risk of users misusing these enhanced CRS, and
2. clarify that assessment of the DE plane only applies to rearward-facing Child Restraint Systems (CRS) in UN Regulation No. 44 and therefore does not apply to forward-facing child restraints that maintain structure of the child restraint behind the head of the dummy.

3. specify the dimensions of the approval number
4. correct the term “Regulation No. 129-02” to “UN Regulation No. 129/02”
5. change the 145 cm stature of the Specific Vehicle Booster seat to the 150 cm stature as this is the upper limit, and
6. modify the approval markings for consistency between technical services and approval authorities and between the labels of products approved under the 02 and 03 series.

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.

Proposal to clarify that UN R139 does not mandate the installation of brake assist systems (BAS) on vehicles but rather specifies requirements for the approval of vehicles should they be equipped with a BAS system.

Proposal to clarify that UN R140 does not mandate the installation of electronic stability control systems (ESC) on vehicles but rather specifies requirements for the approval of vehicles should they be equipped with an ESC system.

Proposal to update a reference regarding ISOFIX exemptions permitted under paragraph 5.3.8.8. (related to vehicles with one seat position per row). The reference should read 5.3.8.8. and 5.3.8.9.
