Revised version of the proposal to remove tables specifying general values for replacement discs and drums that are identical to the original (2.3.3.4), taking into account comments received during the February 2016 GRRF session. The tables are considered superfluous since replacement parts identical to the original parts must by definition have values identical to the corresponding original parts. This proposal also would change the maximum permitted thickness variation of discs for medium and heavy vehicles from 0.030 mm to 0.040 mm (the common OEM specification). This has been changed from the previous proposal of 0.050 mm. This revised proposal clarifies that the proposal would revise the specifications for vehicles of categories M3, N3, O3 and O4 but retain the maximum permitted specification of 0.030mm for vehicles of categories M2 and N2.

One of the outcomes of the work on updating UN R55 was the recognition that agricultural couplings present a set of challenges distinct from other vehicles. This revised proposal takes into account comments received during the February 2016 GRRF session for the establishment of an informal working group to develop a new regulation (UN R55-A) to respond to the specific needs of agricultural vehicle couplings.

Revised version of the proposal, updated by the GRRF secretariat to take into account comments received during the February 2016 GRRF session, for a revised new UN Regulation based on the provisions for tyre-pressure monitoring systems (TPMS) extracted from UN R64 in order to facilitate the application of UN R64 within the International Whole Vehicle Type Approval system. This proposal also seeks to take into account efforts to update US FMVSS requirements for TPMS.

UN R13 allows for the exemption of certain vehicles from the requirement for electronic stability controls. This proposal seeks to clarify the scope of the exemptions to include any special purpose vehicle with a non-standard chassis. The change was prompted by a modified vehicle where use of ESC was not feasible, but where the current UN R13 language left doubt as to whether the ESC requirement was applicable. This revised proposal takes into account comments received during the February 2016 GRRF session.

Revised proposal to align UN R78 with the provisions for anti-lock braking systems used in other regulations, including specific exemptions for certain off-road vehicles as incorporated in UN Regulation No. 13. The proposal clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle. This revised proposal takes into account comments received during the February 2016 GRRF session.

The previous GRRF session considered a proposal to add a trigger threshold requirement and to modify the sampling rate, deceleration limit and data selection criteria for category B brake-assist systems. CLEPA has provided this presentation to clarify the background behind the BAS provisions and facilitate further discussion.

Technical services have reported difficulties in interpreting the requirements and procedures incorporated in the 02 series of amendments to UN R90. Therefore, this submission proposes a special interest group to consider whether an informal working group may be needed to revised UN 92.02.

Revised proposal to ensure that coupling balls do not block rear lighting and/or registration plates. In line with the EU General Safety Rule, Annex IV specification for application of UN R55, couplings that might block lighting or plates must be removable, repositionable, and unlockable in order to make it easier for users to remove them or reposition them when not in use (e.g., towing a trailer.) Coupling balls that are so designed as to be unable to block lighting or plates may still incorporate locks and/or require tools to remove or reposition.

Information and status report on the European Commission Cooperative ITS Deployment Platform established in 2014 to define the European framework for connected vehicles and on the Commission Decision C(2015) 6943 of 19 October 2015 establishing a High Level Group on the Competitiveness and Sustainable Growth of the Automotive Industry in the European Union (GEAR 2030) with particular attention to the evolution of connected and autonomous vehicles.

Presentation explaining the proposal to establish requirements for the approval of replacement brake lining assemblies for L-category vehicles.

Revised proposal to align UN R78 with the provisions for anti-lock braking systems used in other regulations, including specific exemptions for certain off-road vehicles as incorporated in UN Regulation No. 13. The proposal clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle. The European Commission prepared this revised proposal in cooperation with Germany, the Netherlands and IMMA. Given the importance of the changes, the proposal includes transitional provisions.

Revised version of document GRRF/2016/4, proposing to extract tyre pressure monitoring systems from UN R64, pursuant to the discussions held during the February 2016 GRRF session.

UN R90 specifies one minimum shear strength requirement for brake shoe assemblies and one requirement for brake pad assemblies in Regulation No. 90 via a reference to ISO 6312. However, ISO 6312 specifies test methods for hot and cold shear tests. Therefore, GRRF is requested to clarify whether the strength requirements are for both hot and cold shear.

Revised version of document GRRF/2016/9 pursuant to discussions held during the February 2016 GRRF session, proposing a new UN Regulation on tire installation for use within the International Whole Vehicle Type Approval system.

Revised version of document GRRF/2016/8 pursuant to discussions held during the February 2016 GRRF session, proposing a new UN Regulation comprised of provisions concerning electronic stability control systems extracted from UN R13-H.

Revised version of document GRRF/2016/7 pursuant to discussions held during the February 2016 GRRF session, proposing a new UN Regulation based upon brake-assist system provisions extracted from UN R13-H.

Revised version of document GRRF/2016/6 pursuant to discussions held during the February 2016 GRRF session proposing to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations.

Revised version of document GRRF/2016/5, proposing a new UN Regulation based upon provisions for tyre pressure monitoring systems extracted from the current UN R64, pursuant to the discussions held during the February 2016 GRRF session.

UN R13 allows for the exemption of certain vehicles from the requirement for electronic stability controls. This proposal seeks to clarify the scope of the exemptions to include any special purpose vehicle with a non-standard chassis. The change was prompted by a modified vehicle where use of ESC was not feasible, but where the current UN R13 language left doubt as to whether the ESC requirement was applicable.

Working draft from the ACSF informal group to enable the approval of automated steering systems intended to operate at speeds greater than 10 km/h presented for information and discussion at the 81st GRRF session.

Proposal for a new UN Regulation based upon the provisions for tyre-pressure monitoring systems (TPMS) extracted from UN R64 in order to facilitate the application of UN R64 within the International Whole Vehicle Type Approval system. This proposal also seeks to take into account efforts to update US FMVSS requirements for TPMS.

Agenda updated to include informal documents submitted through January 29.

Proposal to

1. change measurement units for drum speed in Annex 7 from min^-1 to km.h^-1 to align the requirements with other tyre regulations;
2. correct wording from “speed category symbol” to “speed symbol” (as defined in para. 2.33);
3. correct wording from “load capacity index” to “load index” (as defined in para. 2.32);
4. correct a reference to para. 3.2.13. of the Regulation in Annex 7, Appendix 1;
5. correct a boundary value of load index in Annex 7, Appendix 1;
6. delete in paragraph 2.1 in Annex 7, the possibility to use the 2.0 m drum diameter to perform the endurance test; and
7. align the text of Annex 10 with Annex 7 of UN R117 pursuant to the adoption of Supplement 5 to the 02 series of amendments to that regulation.

Proposal to clarify the provisions for the minimum heights of markings for tyres with nominal rim diameter codes ≥ 20 and nominal section width ≤ 235 and for tyres with nominal rim diameter codes < 20 and nominal section width > 235. In addition, the proposal aligns the table on minimum marking heights to correspond with the related figure by using lowercase letters to denote dimensions in both (currently, the figure uses lowercase, but the table uses uppercase).

Document GRRF/2016/20 proposes to remove certain design restrictions that impede the application of new technologies, especially related to trailer power steering systems and the use of energy from the towing vehicle, including specification of the connector through which electrical energy is supplied in the proposal. Although this proposal was approved in principle at the 80th GRRF session, it was agreed that the proposal would be reviewed at the 81st GRRF to define an open value [X] in paragraph 2.1.1. of Annex 5. It has subsequently been concluded that this change to paragraph 2.1.1. is not needed. Therefore, this proposal removes the change to the paragraph from GRRF/2016/20.

Presentation on French government views on the approval of automated steering at speeds above 10 km/h under UN Regulation No. 79. The principle recommendation is to restrict amendments to UN R79 to lateral vehicle control as speeds above 10 km/h while setting other work on more advanced capabilities (longitudinal + latitudinal, lane change, passing, etc.) for future separate regulations.

One of the outcomes of the work on updating UN R55 was the recognition that agricultural couplings present a set of challenges distinct from other vehicles. Therefore, Germany proposes the establishment of an informal working group to develop a new regulations (UN R55-A) to respond to the specific needs of agricultural vehicle couplings.

Quick review of the informal group’s anticipated schedule for completing its work on updating the regulation on mechanical couplings.

Further refinements from the informal group on UN Regulation No. 55 to introduce provisions for modular vehicle combinations (e.g., rigid truck + semi-trailer + dolly). This proposal concerns a procedure to identify allowable combinations of performance values Dc and V for drawbar coupling equipment.

Proposal from the informal group on UN Regulation No. 55 to introduce provisions for coupling applications in multi-vehicle combinations ( e.g. rigid truck + dolly + semi-trailer) presently not addressed by the regulation.

Presentation highlighting the growing use of carbon-ceramic (CSiC) brake discs and the need to address these products under UN R90 given that the replacement discs regulation is founded upon conventional cast iron technologies.

Updated version of the proposal to remove tables specifying general values for replacement discs and drums that are identical to the original (2.3.3.4) since such replacements must by definition have values identical to the corresponding original parts. The proposal also would change the maximum permitted thickness variation of discs for medium and heavy vehicles from 0.030 mm to 0.050 mm (the common OEM specification). This revised proposal clarifies that the proposal would revise the specifications for vehicles of categories M3, N3, O3 and O4 but retain the maximum permitted specification of 0.030mm for vehicles of categories M2 and N2.

Proposal to establish a uniform CoP inspection questionnaire to harmonize conformity of production administrative requirements across Contracting Parties under UN R90. The intent is to increase efficiency and lower costs due to the absence of mutual recognition of CoP certifications among approval authorities.
