Proposal from the European Tyre and Rim Technical Organisation (ETRTO) to amend the snow test method for C3 Tyres.

Proposal from the Netherlands to update requirements on the noise test track to the from ISO 10844:1994 to ISO 10844:2011, including provisions for the repaving of non-compliant tracks. The proposal offers two approaches: reference to IS0 10844:2011 or reproduction of the ISO text.

Submission by the GRB secretariat to correct an editorial error where the noise test track specifications should refer to the requirements of ISO 10844:2011 rather than “Annex 4” as stipulated in the original draft.

Proposal by the Chair and Vice-Chair of GRB to allow the use of the test track complying with ISO 10844:2011 in a new series of amendments to the UN R117. This is based upon document GRB-56-20 from the previous GRB session.

Proposal from the Russian Federation to elaborate on the concept of tyre deceleration (dω/dt) in the test technology. The proposal is based on informal document GRB-56-02 from the previous GRB session.

Proposal to update noise test-track requirements from ISO 19844:1994 to ISO 10844:2011 and incorporates transitional provisions to allow repaving of existing, non-compliant test tracks with the ISO 10844:2011 standards. This supersedes document GRB/2012/9.

Series of editorial corrections and clarifications to the resolution.

Corrections to the proposal from the Russian Federation to elaborate on the concept of tyre deceleration (dω/dt) in the test technology.

Response to the proposal to update references to the permissible test tracks (document GRB/2013/2), arguing that the change from ISO 10844:1994 to ISO 10844:2011 is unnecessary since it does not change the test method to measure the tyre rolling noise.

Amendments to the proposal to amend the snow test method for C3 tyres in order to prescribe the wider of the possible speed ranges. Corrects wording to replace “blocking differential” with “differential lock” and mandatory use of differential lock in certain cases.

Presentation on the development of tire rolling resistance standards by the GRRF and GRB.

Text prepared by the International Organization of Motor Vehicle Manufacturers (OICA) in order to introduce the concept of “revision of approvals” in the regulations under GRB responsibility.
