Proposal to correct references to paragraphs in Regulations Nos. 30 and 54 which have to be updated pursuant to renumbering in the source regulations.

Proposal 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.

Revised proposal pursuant to GRRF discussions to enable activation of the ESC optical symbol in cases of a corrective steering function intervention when the CSF intervention is activated under the control of an ESC system. The aim is to avoid separate requirements for brake-actuated and steering-actuated vehicle stability functions (VSF) that would lead to two optical warnings where only one is necessary. This would enable use of the ESC intervention tell-tale for CSF steering intervention.

Proposal to restrict manual deactivation of AEB systems to speeds under 30 km/h. The proposal would require automatic reactivation of the AEBS when the vehicle speed exceeds 30 km/h.

Proposal to align the Russian text with the original English text. In the English versions, the title of Annex 1 (Communication concerning the approval or extension or refusal or withdrawal of approval or production definitely discontinued of a retreading production unit pursuant to Regulation No. 108) is essentially identical to that use for Annex 1 of UN R109. Therefore, this proposal amends the title of Annex 1 in the Russian version of UN R108 to coincide with that of the Russian version of Annex 1 in UN R109.

Proposal to introduce provisions for driver-initiated automated lane-change systems (Category C ASCF) and for automated emergency steering functions (ESF).

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”.

Formal proposal from the ACDC informal group for consideration by GRRF for a new Regulation on uniform provisions concerning the approval of mechanical coupling components of combinations of agricultural vehicles.

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, clarify tyre width tolerances, correct paragraph numbering and references, align the text editorially with UN R30 and to make other editorial improvements,

This document consolidates previous documents GRRF/2017/19 and informal document GRRF-84-17 taking into account the request for addition of tyre sizes and tyre classification codes common in the United States and standardised by the Tire and Rim Association, but needed to be added to UN Regulation No. 106 in order to permit their type approval in order to conform to Regulation EU 167/2013 for tyres to be exported to Europe. It includes addition/modifications of some paragraphs to the main text of the Regulation as well as the addition of some tyre size designations to Annex 5 and Annex 7:

1. ISO 4251-4 replaced by ISO 18805
2. Paragraph 2.33.2 deleted since new tables for IF and VF were added to Annex 7
3. 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
4. Para 6.1.2. amended to align the wording to the headers in Annex 5 and to correct the reference to the footnote
5. Para 6.2.1. amended to restore the proper references after renumbering resulting from the latest Supplements
6. 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”
7. 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.
8. 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.
9. 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.
10. Annex 7, Part A amended to conform with Tire and Rim Association specifications for code designated diagonal tyres with speed symbol A8.

Proposal to add markings for the inflation pressure to be used for measurements and tests.

Proposal to introduce provisions for the approval of retreaded tyres marked with the alpine symbol (“3PMSF” or “snowflake symbol”).

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

Proposal to introduce provisions for the approval of Remote Control Manoeuvring (RCM) systems, defined as driver-actuated systems on off-road vehicles used for navigating exceptionally difficult terrain. This proposal seeks to permit remote manoeuvring capability provided that the vehicle is designed to operate off-road and the off-road location is confirmed throughout the whole period that the function is in use.

Consolidated version of UN R54 incorporating the proposed amendments in document GRRF/2018/5.

Consolidated version of UN R106 including ETRTO proposed amendments (see documents GRRF/2018/6 and GRRF/2018/7).
