Paper prepared by OICA contesting the proposal from FEMFM to apply the “identical disc/drum” philosophy to the definition of identical brake linings.

20. The expert from FEMFM introduced ECE/TRANS/WP.29/GRRF/2013/4 taking into account the remarks received during the previous session of GRRF. He recalled the purpose of the proposal and underlined that so called “chemically and physically identical replacement brake lining assemblies” and “chemically and physically identical drum brake linings” should not have to be retested but should be approved on the basis of the homologation of the original equipment supplier. In that case, the applicants for approval should only demonstrate that they supply the brake lining assemblies or the drum brake linings for the vehicle or brake manufacturer as original equipment for the specific model(s) for which approval is being sought, and that they produce the parts under the same production conditions, quality assurance system, and with the same results of the conformity of production tests as for the original parts. The expert from OICA introduced GRRF-74-19, expressing some concerns with the proposal made by FEMFM. The expert from Spain underlined the need for GRRF to confirm the endorsement of the philosophy behind the proposal made by FEMFM. The expert from the Russian Federation observed that the proposal is consistent with an approach which is already used in other parts of Regulation No. 90. The expert from CLEPA volunteered to organize a meeting with OICA, FEMFM as well as interested Contracting Parties and NGOs interested in this issue. GRRF agreed to resume consideration at its next session.

He recalled the purpose of the proposal and underlined that so called “chemically and physically identical replacement brake lining assemblies” and “chemically and physically identical drum brake linings” should not have to be retested but should be approved on the basis of the homologation of the original equipment supplier. In that case, the applicants for approval should only demonstrate that they supply the brake lining assemblies or the drum brake linings for the vehicle or brake manufacturer as original equipment for the specific model(s) for which approval is being sought, and that they produce the parts under the same production conditions, quality assurance system, and with the same results of the conformity of production tests as for the original parts. The expert from OICA introduced GRRF-74-19, expressing some concerns with the proposal made by FEMFM. The expert from Spain underlined the need for GRRF to confirm the endorsement of the philosophy behind the proposal made by FEMFM. The expert from the Russian Federation observed that the proposal is consistent with an approach which is already used in other parts of Regulation No. 90. The expert from CLEPA volunteered to organize a meeting with OICA, FEMFM as well as interested Contracting Parties and NGOs interested in this issue. GRRF agreed to resume consideration at its next session.

24. The expert from CLEPA, recalling the purpose of ECE/TRANS/WP.29/GRRF/2013/4, reported on the work of OICA, CLEPA and CLCCR and introduced GRRF-75-18 amending the original proposal. GRRF noted the completion of technical work. The expert from OICA also introduced GRRF-75-19 supporting the technical content of the proposal but disagreeing with legal aspects such as intellectual property, product liability and reputation issues that may occur. The expert from CLEPA addressed the concerns of OICA (GRRF-75-41). The expert from Spain noted some administrative and procedural difficulties for Type Approval Authorities that this proposal may create. The expert from France requested a justification for the deletion proposed in Annex 4B. GRRF agreed, in principle, with the technical provisions and requested the secretariat to distribute GRRF-75-18 with an official symbol for further consideration at its next session. GRRF requested the Chair to report to WP.29 at its November 2013 session on both the technical and the legal aspects.

Proposal to align M1 vehicle braking performance requirements with UN R13-H provisions and clarify those for N1 vehicles in Annex 3 of UN R79.

29. The expert from CLEPA presented GRRF-74-37, on behalf of CLCCR, proposing to introduce into Regulation No. 79 provisions permitting the type approval of positive steering of trailers using energy supply and electrical control from the towing vehicle. His proposal focused on the energy supply connectors and the transmission of steering control data (digital information interchange). The expert from the Netherlands proposed extending the work to the power supply provisions necessary to guarantee a good functionality as well as a sufficient level of safety. GRRF agreed to add this as a new item on the agenda of the next session.

30. The expert from CLEPA introduced ECE/TRANS/WP.29/GRRF/2013/5 proposing to align the test speed and braking performance requirements for vehicles of the category M1 and N1 in the event of energy source failure with those in Regulations Nos. 13 and 13-H. GRRF adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2013 sessions as draft Supplement 4 to the 01 series of amendments to Regulation No. 79.

Proposal to establish an expert group with a mandate to prepare new harmonized regulations for lane-keeping and parking-assist systems.

31. The expert from Japan proposed to establish an informal group on LKAS and PAS (GRRF-74-40) and introduced a draft terms of reference as reproduced in ECE/TRANS/WP.29/GRRF/2013/5 and GRRF-74-05. He presented GRRF-74-41, showing the need for minimum requirements applying for those systems, if fitted in a vehicle. The expert from OICA introduced GRRF-74-18, objecting to the need for such a Regulation on these new technologies, claiming that Annex 6 of Regulation No. 79 covered those systems. GRRF agreed to reconsider the proposal at its September 2013 session and invited Japan to provide a more detailed justification for such systems, including a cost-benefit analysis if possible.

38. The expert from Japan withdrew ECE/TRANS/WP.29/GRRF/2013/6 as amended by GRRF-74-05. Referring to GRRF-75-34, he presented GRRF-75-33 with statistical data and estimations on LKAS benefits and invited interested experts to a meeting to further discuss this item. The expert from OICA introduced GRRF-75-12 as well as GRRF-75-04 correcting GRRF-74-18 containing comments on the Japanese proposal to regulate LKAS and PAS. The expert from the Russian Federation noted that including specific requirements on LKAS into Regulation No. 79 would be against the spirit of IWVTA. GRRF agreed to resume consideration of this subject at its next session.

Text prepared by the International Motorcycle Manufacturers Association (IMMA) in order to introduce amendments to clarify the current text for the use of Combined Braking Systems (CBS).

18. The expert from IMMA introduced GRRF-74-35, superseding GRRF-73-10, proposing to clarify some provisions and to simplify the test procedures in Regulation No. 78. The proposal received several comments, including GRRF-74-34, introduced by the expert from India. GRRF agreed to reconsider IMMAs proposal on the basis of an updated official document taking into account the comments received. The expert from IMMA volunteered to prepare the document and to submit it in due time to the secretariat. The expert from IMMA introduced ECE/TRANS/WP.29/GRRF/2013/7, a proposal to amend certain requirements in Regulation No. 78. GRRF considered that clarification of the intention of the proposal and further justification was necessary. The expert from IMMA agreed to amend the document in line with the comments received and submit for consideration at GRRFs September 2013 session.
