Proposal to improve the Engine Control Unit (ECU) torque signal validation requirement in the 06 series of amendments to R49 with regard to dual-fuel or flex-fuel vehicles. Under the regulation, the ECU torque information can be calibrated only to one fuel’s heat value (usually the basic reference fuel) even though the heat value of the alternative fuel is different. In order to increase the accuracy of the torque values used for calculating the emission results during in-service conformity testing, OICA proposes to change the provisions to either:

1. Demonstrate that both fuels comply because the ODB system is able to detect the fuel used, or
2. Determine the torque deviation caused by the alternative fuel heat value compared to the standard fuel and apply this correction factor to calculate a more accurate power signal for the emission calculation.

Proposal to clarify the text with regard to the extension of approvals for category N vehicles in order to avoid a possible misinterpretation that extensions may not be granted to vehicles with a reference mass greater than the mass of the type-approved vehicle.

Addendum from GRPE to include amendments to provisions for reagent tank specifications and limits for triggering warning and driver inducement systems to the draft Supplement 11.

Proposal to clarify the text with regard to the extension of approvals for category N vehicles in order to avoid a possible misinterpretation that extensions may not be granted to vehicles with a reference mass greater than the mass of the type-approved vehicle.

Addendum from GRPE to include amendments to provisions for reagent tank specifications and limits for triggering warning and driver inducement systems to the draft Supplement 7.

Proposal to clarify the wording of the determination of the net power for electric motors and to correct an error in the formula presented in paragraph 5.4.2. Diesel engines – Factor αd. The parameter “f_m” in the equation should be a superscript (e.g., meaning “to the power of f_m”). Through a transcription error, this factor was rendered in normal text.

Proposal of a consolidated revision of UN R96 to align the UN Regulation with Regulation (EU) 2016/162 concerning gaseous and particulate pollutant emission limits and type-approval for internal combustion engines for non-road mobile machinery.

Proposal to align UN R120 with the proposed 05 series of amendments to UN R96.

The 02 series of amendments to UN R79 introduced requirements for RCP systems. An RCP system requires the engagement of an EPB (electronic parking brake) once the manoeuvre has finished and the ignition is switched off. This proposal would allow the release or disconnection of the EPB by a remote control system (approved to R79) so the RCP can subsequently drive the vehicle out of a parking spot.

Proposal to introduce formulae for tyre sizes in Annex 5, Table B, add sizes in Annex 5, Part II, Tables C and E for old sizes that do not follow the guidelines/formulae applicable for high flotation tyres, amends footnotes in Annex 5, Part II, Table B in order to clarify categories of use, clarify tyre width tolerances, correct paragraph numbering and references, align the text editorially with UN R30 and to make other editorial improvements.

Proposal to clarify the references to UN R10 in UN R89. This was part of a collective amendment proposal concerning (in addition to UN R89) UN R13, UN R13-H, UN R79; UN R130 and UN R131. Proposal also to

1. exempt cases where the driver has temporarily deactivated the speed limiter from the warning requirement for excess speed in in order to reduce driver distraction
2. introduce throttle control via adjustment of the accelerator pedal position
3. to correct an editorial error in paras. 5.2.5.4.2. and 21.2.5.4.2.

Proposal to add tyre sizes and tyre classification codes common in the United States and standardised by the Tire and Rim Association, but needed under UN Regulation No. 106 in order to permit their type approval in conformity with Regulation EU 167/2013 for imported tyres. The proposal adds kPa marking specifications for use in measurements and tyre testing. The proposal further includes changes to the text and addition of tyre size designations to Annex 5 and Annex 7:

1. Paragraph 2.33.2 deleted since new tables for IF and VF were added to Annex 7
2. Paras 3.2., 3.2.2. and 5.4. modified because “tyres submitted for approval” cannot bear an approval mark until approved and the “only” as it is written can be misunderstood. Para. 3.2.2. was aligned to the wording in other UN Regulations. Reference to para. 3.3 in paragraph 5.4. is deleted because paragraph 3.3 does not refer to specific markings
3. Para 6.1.2. amended to align the wording to the headers in Annex 5 and to correct the reference to the footnote
4. Para 6.2.1. amended to restore the proper references after renumbering resulting from the latest Supplements
5. The amendment of Annex 5, Table 5 adds the value for the overall diameter (D) in column (*) that applies to tyres marked with classification code “I-3”
6. Annex 5, Table 6, Note 1 amended because most of the tyre sizes listed in the table, especially those identified by the “classification code I‐3” (i.e. Traction tread), are currently available in both versions: ‘implement’ to be used on agricultural machinery and ‘IND’ to be used on construction vehicles. The two types of tyres have the same type of size designation and the same dimensions. Therefore some manufacturers identify those tyres with the suffix ‘IND’ rather than with the suffix ‘IMP’ thus applying the variation of load capacity with speed as published in Annex 7 Part E. The reason for this proposal is to avoid a duplication of tables with a new table only replacing the suffix IMP with the suffix IND.
7. The addition of the footnote to Annex 5, Table 7 answers the request by GRRF to introduce appropriate formulae in the Regulation instead of continuously updating Annex 5.
8. References in Annex 7 corrected pursuant to the renumbering following the introduction of three new paragraphs in Supplement 15 approved during the 172nd session of WP.29.
9. Annex 7, Part A amended to conform with Tire and Rim Association specifications for code designated diagonal tyres with speed symbol A8.

In order to have a Regulation on the retreaded tyres with definitions and provisions structured in the same way of those previously introduced in amendments of “new tyres” Regulations, this amendment:

1. Indicates that for the purpose of this Regulation “tyres” means “pneumatic tyres”, so all the text has been reviewed
2. Introduces a definition of :
   • “retreader” copy based on that “manufacturer” in the tyres regulations
   • Brand name", “Trademark”, “Trade description” and “Commercial name” as defined in the tyre regulations
   • Material manufacturer / material supplier
3. Takes into account the rounding rules (already approved in the other tyre regulations) for the calculation of width and diameter of the tyres
4. Aligns the title and the provisions of the para. 12 related to the names and addresses of Technical Services, Approved Laboratories and administrative Department with their equivalent in the tyres regulations

Addendum from GRRF to include provisions for PSI or kilopascal (kPa) markings and to clarify inflation pressure under the test procedures in the proposal for Supplement 9.

Proposal to clarify the purpose of UN R139 which was originally established through the extraction of brake assist system (BAS) provisions from UN R13-H on brake systems. Within the context of UN R13-H, the BAS provisions were written to assess performance in cases where a vehicle was fitted with a brake assist system. As a stand-alone regulation, UN R139 applies only to vehicles that are equipped with BAS. Therefore, this supplement proposes to refine the text to remove the “if fitted” language and ensure that UN R139 can only be applied to a vehicle equipped with a BAS.

Proposal to remove “if fitted” language from the text to clarify that UN R140 can only be applied to a vehicle equipped with a ESC system. UN R140 was originally established through the extraction of electronic stability controls (ESC) provisions from UN R13-H on brake systems. Within the context of UN R13-H, the ESC provisions were written to assess performance in cases where a vehicle was fitted with an electronic stability control system. As a stand-alone regulation, however, UN R140 applies only to vehicles that are equipped with ESC. The proposal also would correct an apparent error in to Annex 4, paragraph 2.1. where the reference to “ISO 15037 Part 1:2005” should read “ISO 15037 Part 1:2006”.

Proposal to exclude pure electric vehicles, including vehicles with auxiliary electric propulsion, from the scope of the regulation, to include sound-level measurement conditions for powered cycles equipped with compressed air engine and to introduce sound-level limits for powered cycles.

Proposal to add indoor testing, including ISO 362-3, as an alternative to the type approval tests in Annex 3. In addition, UN R51 allows the use mechanical or electronic devices to control the gear shifting and measures to avoid accelerations greater than 2.0 m/s². However, the measures are not defined and the manufacturer or technical service is not obliged to document the methodology in the test report. This proposal introduces a table with examples for devices and measures for reference and would require documentation of methodology used.

Proposal to correct Table 1 by deleting “F1” (this fixture is part of a corresponding ISO Standard but not in UN R16) and to replace “universal” by “i-Size” in the title of Appendix 5, as UN R129 booster seats can be only i-Size or specific.

Proposal to clarify and correct the reference in paragraph 8.3.6. to UN R14 and the new UN Regulation on ISOFIX anchorages with regard to the measurement of the pitch angle used for the geometrical assessment of the installation of ISOFIX child restraint fixtures. This proposal relates directly to the supplements presented in document WP.29/2017/120.

Proposal to correct a mistake in Supplement 17 to UN R75 (adopted document WP.29/2017/8). Annex 7, Paragraph 1.2., Footnote 1 should refer to UN R54, not UN R106.

Requirements for the approval of:

1. Compressed hydrogen storage systems for hydrogen-fuelled vehicles of categories L₁, L₂, L₃, L₄ and L₅ on their safety-related performance
2. Specific components for compressed hydrogen storage systems for hydrogen-fuelled vehicles of categories L₁, L₂, L₃, L₄ and L₅ on their safety-related performance
3. Hydrogen-fuelled vehicles of categories L₁, L₂, L₃, L₄ and L₅ incorporating compressed hydrogen storage system on its safety-related performance.

Amendment 1 to UN GTR No. 19 adds a test procedure for sealed fuel tank systems in addition to modifications related to testing of non-sealed fuel tank systems which were raised during the work on sealed fuel tank systems.

Proposal of minor corrections to the draft Amendment 1 to GTR 19 (WP.29/2018/73).

Background information on the development of Amendment 1 to GTR 19.

Proposal to clarify and correct the reference in paragraph 8.3.6. to UN R14 and the new UN Regulation on ISOFIX anchorages with regard to the measurement of the pitch angle used for the geometrical assessment of the installation of ISOFIX child restraint fixtures. This proposal relates to the supplements presented in document WP.29/2017/120.

Proposal to delete a reference to the measurement of the femur bending moments because such measurements are unnecessary under the full width rigid impact test. Specifically, paragraph 5.2.4.1. is changed from “The axial compressive force and the bending moments are measured with a CFC of 600.” to read “The axial compressive force is measured with a CFC of 600.”

Proposal to establish a WP.29 program to develop a UN GTR specifying a methodology for determining the real driving emissions of light-duty vehicles based on the European RDE methodology appropriately adapted for specific regional traffic conditions and boundaries.

Proposal to update the list of UN Regulations subject to UN R0 (Annex 4), including addition of UN R14 (safety belt anchorages) and UN R34 (rear impact and fire risk).

Proposal to align the approval code for light sources approved according to Regulation No. 37 with the approval number as prescribed by Revision 3 of the 1958 Agreement, schedule 4. Parallel proposals have been submitted with regard to UN R99 and R128.

Proposal to enable approval of side-marker and position lamps with regard to switching requirements when mutually incorporated. Vehicles include designs where lamps wrap around vehicle corners. In cases where optional side-marker lamps are grouped with a position lamp that is reciprocally incorporated with the direction indicator, it should be possible to switch off the side-marker lamp (as can be done with the position lamp) in order to improve conspicuity of the direction indicator.

The proposal also defines specifications for the design and operation of external status indicators for Vehicle Alarm Systems (VAS), Alarm Systems (AS) and immobilizers under UN R48 pursuant to provisions of UN R97 and R116.

The proposal also corrects and clarifies the following:

• para. 5.7.2.1. editorial alignment of text with current terminology
• replace undefined “effective outlet” terminology with defined “apparent surface” reference
• reintroduction of missing reference to “transverse plane” in paras. 5.10.1. and 5.10.2.
• para. 6.2.9. and related subsequent paragraphs to clarify the application of the 2000 lumen criteria
• para. 6.26.9.2. to correct a cross-reference with UN R23
• measurement of the minimum height in relation to the ground for dipped beam headlamps (para. 5.8.2).

• para. 5.7.2.1. editorial alignment of text with current terminology
• replace undefined “effective outlet” terminology with defined “apparent surface” reference
• reintroduction of missing reference to “transverse plane” in paras. 5.10.1. and 5.10.2.
• para. 6.2.9. and related subsequent paragraphs to clarify the application of the 2000 lumen criteria
• para. 6.26.9.2. to correct a cross-reference with UN R23.

Proposal to

1. remove the prohibition against lamps “reciprocally incorporated” with any other lamp, correcting an oversight from a previous amendment process, and
2. update the definition of “stop lamp” in order to allow the use of different stop lamp activation methods for powered two-wheelers as currently applicable for four-wheelers; e.g. by the application of a retarder or a similar device.
