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 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.

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

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.

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 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.

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.

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.

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 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.

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.

Revised proposal, based on document GRRF/2016/38 and revising GRRF-82-24, to:
a) Align definitions and contents of paragraphs with the other tyre regulations (UN R30, R54, R117, etc.);
b) Include a definition of “Manufacturer” extracted from the resolution “R.E.3”;
c) Adopt a common definition and use of the terms “Manufacturer’s name”," Brand name", “Trademark”, “Trade description” and “Commercial name” and their links;
d) Clarify which markings shall be moulded on both sidewalls of the tyre; and those which shall be moulded on one sidewall only;
e) Add information in the certificate to clarify the relationship with the certified products;
f) Align definitions with Regulation EU 167/2013 which defines vehicles in category S as “interchangeable towed equipment” and includes tread patterns for ‘implement traction tyres’ that consist of blocks rather than lugs or cleats;
g) Eliminate redundant marking requirements;
h) Clarify the inflation pressure to be used for measurements and tests and related tyre markings;
i) Align the current rules for calculating the dimensional limits in accordance with ISO, all major tyre standards, and as proposed for UN R30, R54, and R75.

Proposal by the informal working group on Regulation No. 55 to introduce:
a) Correction of an error in Annex 5, figures 12 and 17;
b) An amendment that concerns identification of worst cases for design assessment;
c) Clarifications on minimum articulation angles.

Proposal to:
a) Align some definitions and some contents of paragraphs with the other tyre regulations (Regulations Nos. 30, 54, 117, etc.);
b) Include a definition of “manufacturer” extracted from the resolution “R.E.3”;
c) Adopt a common definition and use of the terms “Manufacturer’s name”," Brand
name", “Trademark”, “Trade description” and “Commercial name” and their links;
d) Clarify the designation of the categories of use;
e) Remove the word “normal” in the definition of “Reinforced” tyre to avoid confusion
with the category of use “normal”;
f) Add some information in the certificate to the attention of the Type Approval
Authorities for making easier the relationship between this one and the products.

Proposal to clarify the minimum heights for 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 corrects the use of uppercase letters to denote dimensions where lowercase letters had been inserted.

Correction of the paragraph numbering pursuant to the adoption of Supplement 21 and deletion of a redundant note at the end of paragraph 6.1.5.3.3.

Proposal to allow for the case of a tyre designed for a special application that also fulfills the requirements for a snow tyre such that the tyre, at the manufacturers initiative, shall be marked with the inscription M+S or M.S or M&S while remaining in the category of use “special use tyre”. The proposal further adds “test laboratories” in the headline of paragraph 12. as quoted in subparagraph 12.1. in document WP.29/2016/51 as adopted during the June WP.29 session with the aim of harmonizing the tyre regulations.

Proposal to correct paragraph number references due to the recent renumbering of definitions.

Proposal to clarify paragraph 8.1.2. The paragraph aimed to verify that the compensator can accept a difference of the travel when one brake operates in forward direction and the other in rearward direction with a margin of twenty per cent.
