Report of the special meeting held in Paris on 21 November 2013 to discuss wet grip values for Class C2 and C3 tyres.

Proposal to specify that safety aspects of ESC systems can be assessed under this new regulation or under UN R13-H. The objective of the proposed wording is to avoid redundant certification of the complex electronic control systems (CEL) aspects of ESC according to both the proposed ESC regulation and UN Regulation No. 13-H (keeping unchanged the level of safety). The proposal would permit the applicant to show evidence that CEL compliance has already been achieved according to Annex 8 of UN Regulation No. 13-H as an alternative to demonstrating compliance with the CEL annex of the ESC regulation.

Proposal to specify that safety aspects of brake assist systems can be assessed under this new regulation or under UN R13-H. The objective of the proposed wording is to avoid redundant certification of the complex electronic control systems (CEL) aspects of ESC according to both the proposed BAS regulation and UN Regulation No. 13-H (keeping unchanged the level of safety). The proposal would permit the applicant to show evidence that CEL compliance has already been achieved according to Annex 8 of UN Regulation No. 13-H as an alternative to demonstrating compliance with the CEL annex of the BAS regulation.

Proposed amendments to UN R13-H to confirm that the complex electronic control system (CEL) requirements may be satisfied through an approval conducted under another regulation (e.g., the pending new ESC and BAS regulations) and to delete the marking requirement concerning ESC systems which will no longer be within the scope of UN R13-H.

Transmitted by the experts of the subgroup on UN R0 pursuant to their 9th session held during 21-22 January 2014 (Document SGR0-08-13-rev.1).

Proposal to amend the draft text for the proposed new regulation on BAS which would extract the BAS provisions from the current UN R13-H on light vehicle braking systems. The intention is to clarify the meaning of the text in places where it is ambiguous when taken out of the context of UN R13-H.

Latest version (superceding WP.29/2014/26) of the revision of the 1958 Agreement to enable the deployment of the International Whole Vehicle Type Approval system and to facilitate the global application of the Agreement and its system for the mutual recognition of type approvals. This version proposes solutions to all the remaining open issues except the question of two-thirds voting raised as a measure to address concerns of non-EU governments over the current simple majority procedure.

Presentation concerning all-terrain tires pursuant to the proposal to include provisions under UN R75 to enable the type approval of such tires.

Proposal to elaborate on the concept of tyre deceleration (dω/dt) in the test procedures. The Russian Federation has developed a “Deceleration Calculator” for use in the UN R117 procedures. Following work by an ad hoc group (including NAMI, UTAC, and ETRTO) formed to review and validate this tool, Russia has prepared this new proposal, modifying the version (document GRB/2013/10) submitted at the last GRB session. The changes primarily concern the explanation of the tool rather than the basic mathematical equations.

Report of the ad‐hoc working group organized in accordance with the recommendation of the 58th GRB session to consider testing and evaluation of the variant method using the dω/dt form proposed by Russia.

Full report of the ad hoc group on the development of the method for determining tire rolling resistance using the variant dω/dt method.

Actions and decisions taken during the 9th session of the expert group amending the 1958 Agreement in order to accommodate the proposed international whole vehicle type approval system.

India noted an erroneous reference to “ESC” in the original document where “BAS” was clearly intended.

Proposed corrections and clarifications to the draft text of the new regulation to separate ESC provisions from Regulation No. 13-H (document GRRF/2014/12).

Presentation on definitions, applications, and regulatory options for the type approval of L-category vehicle all-terrain tires.

Amendments to the draft new regulation for the approval to tires installed on a vehicle in order to avoid overlap with UN R64 on spare tires.

Editorial corrections by the ETRTO to its proposal to insert a new marking provision and under “categories of use”, a definition for construction application (industrial tractor) tyres into UN R106.

Explanation of three options developed for handling the approval of electronic stability controls (ESC) and brake-assist systems (BAS) under regulaitons separate from UN R13-H (light vehicle braking) while fulfilling the requirements of complex electronic systems (CEL).

Submission of the wet grip limit values for Class C3 tires as agreed to within the Working Party on Brakes and Running Gear (GRRF). These values were originally proposed in document WP.29/2013/66.

Update by the chair of the subgroup on the development of UN R0 of the IWVTA informal group.

Voting form for the adoption vote on light vehicle emissions and tires.

Working draft of the proposed UN regulation on whole vehicle type approvals transmitted by the chair of the subgroup on development of UN Regulation 0.
