Proposal to improve and clarify the text of the Regulation.

Proposal to exempt Zone I from opaque obscuration requirements of GTR 6 under certain conditions.

Proposal to introduce provisions for the optional use of laminated-glass panes with improved mechanical properties, particularly for the front, exterior, forward-facing glazing of the upper deck of a double-deck vehicle.

Proposal to amend GTR including:

• Amendment to the scope
• Addition of new definitions (Section 2)
• Harmonization of the Load Range concept in relationship to Inflation Pressure (Section 2)
• Alignment of the provisions with the most recent developments in UN Regulations Nos. 30 and 54 (Sections 3.3 and 3.5, Annexes 3 and 6)
• Harmonization with FMVSS 139 requirements relative to UN Regulation No. 54 “PSI” index (Sections 3.7 and 3.8)
• Addition of new harmonized provisions for physical dimensions of LT/C tyres (new Section 3.5.2; old Sections 3.20 & 3.21 deleted)
• Addition of new harmonized provisions for high speed test for LT/C tyres (new Section 3.6.2.2, old Section 3.16 modified with endurance test only and renumbered 3.9, old Section 3.19 deleted)

Proposal to introduce changes/additions in the Change of Design Table to better specify appropriate test requirements for CNG cylinders with composite materials and, in some cases, to harmonize with International Standard Organisation (ISO) standard 11439.

Proposal to:

1. clarify that the application of an AECD approval to other vehicle categories than M₁ and N₁ is not mandatory,
2. align the power supply requirement of Part III, para. 34.1 with the corresponding requirement in Part II, para. 25.1.
3. clarify with regard to para. 34.1 that if the vehicle is equipped with both
   • -a “back-power supply” as listed in para. 35.10.1 and
   • -a “Power supply other than back-up power supply mentioned in paragraph 35.10.1” as listed in para. 35.10.2
   both should be tested according to Annex 9. The “Power supply other than back-up power supply mentioned in paragraph 35.10.1” should indeed only be tested if it is the only power supply for the AECS.
4. include two-year transitional provisions
5. remove the exclusion of M₁ and N₁ not equipped with a side airbag and to specify that the AECS shall be able to output the navigation solution in an NMEA-0183 protocol format (RMC, GGA, VTG, GSA and GSV message), among other clarifications.

Proposal to specify that "the motor-vehicle’s user instructions (e.g. owner’s manual, vehicle handbook) shall clearly specify that the removable or repositionable mechanical coupling device shall always be removed or repositioned when it is not in use.” The purpose is to comply with an EU General Safety Regulation provision that prohibits couplings from obscuring rear lighting components or registration plates.

Proposal to clarify that UN R144 does not specify the frequency (number) of attempts or the duration of efforts to establish a network connection (voice or data transmission) for automatic emergency call systems. This proposal has been deferred to the June 2020 WP.29 session.

Proposal to correct erroneous references (to annexes in the regulation as well as to UN R94 and R95) in the text and to correct an inconsistency in the text (paragraph 26.7.2. refers to situations where the AECS is not equipped with a back-up power supply; however, the subparagraph 26.7.2.3. refers to an AECS with a back-up power supply).

Proposal to add a missing footnote concerning the exemptions for heaters located outside the passenger compartment using water as a transfer medium and to clarify that it is not necessary to apply Annex 4 for the heat pump because the heat transfer fluid does not contain polluting air.

Proposal in line with ISO 2575 to allow for the use of different colors (e.g., red, yellow, green) to convey the status modes (e.g., failure, active) of seven functions via modification of footnote 18 under Table 1.

Proposal to clarify provisions for periodic testing and periodic requalification of Compressed Natural Gas (CNG) cylinders and Liquefied Natural Gas (LNG) tanks.

Proposal to introduce a definition for “Aerodynamic devices” and ensure that such devices shall not compromise the functionality of rear underrun protection devices.

Proposal to

1. clarify test procedures allowing non-random selection of parameter combinations and
2. provide for protrusion requirements for Blind Spot Information Systems (BSIS) external elements.

Proposal to enable the use of small indicative lines to assist the driver in discriminating among two or more fields of vision rendered as a combined continuous image on a display.

Proposal to exempt rear edges of fenders and rear edges of A pillars under certain conditions from the requirement that sheet metal edges be folded back or fitted with a shield.

For escape hatches on buses of Classes A and B, proposal to allow a maximum length of 1600 mm equally spaced to cover the shortest vehicles, so the allowed space should be the maximum of either the third of the length or 1600 mm. This proposal will not affect the positioning requirements for any mid-sized and larger buses.

This proposal will not affect the positioning requirements for any mid-sized and larger buses.

Proposal to align approval numbers and markings under UN R90 with Schedule 4 of Revision 3 to the 1958 Agreement. Please note that WP.29 adopted document WP.29/2019/47 as Supplement 5 to the 02 series of amendments to UN R90 during its June 2019 session. Therefore, this proposal (if adopted) would be Supplement 6.

Proposal to transpose the modified requirements for non-original replacement exhaust silencing systems (NORESS) from UN R92 (Replacement exhaust silencing systems for motorcycles) into UN R59.

Proposal for an amendment to complement the content of working document GRVA/2018/5. The proposal includes amendments to:

1. The Standard Reference Test Tyre (SRTT) denominations
2. Remove the discrimination between the two Class C3 tyres
3. Clarify that there are no C3 tyres in the scope of this UN Regulation “not marked with speed symbol”
4. Align Annex 6 with the most recent amendments made to standard ISO 28580
5. Define “standard deviation” as appropriate in the text
6. Clarify that, in the cases of C2 and C3 tyres, the “Reference (test) pressure” and the value “Pr” correspond to the indication of the inflation pressure which is always marked on the sidewall
7. Use “repeatable” instead of references to “reproducibility”
8. Update test report forms
9. Include the date on which the new proposed supplement of UN Regulation No. 117 will apply
10. Improve the description of the evaluation of the rolling sound emission test
Correct the figure in Annex 2, Appendix 2, and
11. Update cross references pursuant to paragraph renumbering.

Proposal to define “electronic” as a “principle of operation by electric or electro-magnetic force with amplifier and speaker or resonator”.

Proposal to introduce mandatory additional sound emission provisions (ASEP) tests and to correct inconsistencies in the ASEP exemption conditions for vehicles with variable gear ratios or automatic transmission with non-lockable gear ratios.
