Proposal for changes to the definitions of vehicle type (adding tire dimensions), ‘pre-acceleration’, and reference points (para. 2.11) and to the Annex 10 test procedures for medium to heavy vehicles.

Presentation by the China Automotive Technology and Research Center.

Presentation by the Norwegian Public Roads Administration on noise abatement activities of the Conference of European Directors of Roads.

This proposal would revise the transitional provisions of the proposed 03 series of amendments to Regulation No. 51 (see GRB/2012/2). OICA believes the preceding text may create problems in the granting or accepting of type approvals under the previous series.

JASIC presentation in support of Japanese positions for the 03 series of the UN regulation on vehicle noise (UN R51). The presentation addresses a three-stage, six-year transition to more stringent noise limitations and proposes additional vehicle subcategories.

European Commission presentation on plans for adopting new noise emissions test procedures, limit values, and minimum noise requirements for quiet vehicles.

Revised presentation by the China Automotive Technology and Research Center (CATARC) on proposed new noise limit values.

Updated JASIC presentation in support of Japanese positions for the 03 series of the UN regulation on vehicle noise (UN R51). The presentation addresses a three-stage, six-year transition to more stringent noise limitations and proposes additional vehicle subcategories.

Proposal of transitional provisions for the 03 series of UN R51 on vehicle noise. Importantly, the proposal seeks to address the handling of transitions and extensions between the 02 and 03 series, perhaps offering a template for transitional provisions in general.

Netherlands presentation to explain the background and rationale behind the working documents GRB/2012/02 and GRB/2012/03, respectively addressing the current status of decisions in GRB and proposals for further improvement (based on GRB and ISO work) to UN R51 on vehicle noise.

Table offering the Japanese position on new limit values for 03 series of amendments to Regulation No.51. The limit values are based on the TNO assessment study and German proposal with sub-categories proposed by Japan based upon a database of noise levels of Japanese vehicles.
