Test procedure proposal updated with comments from the 2nd REG58-QRTV group session.

Proposal for an alternative to the proposal (document GRRF/2015/9) to restore transitional provisions incorrectly deleted by Supplement 6 to the 02 series of amendments.

This proposal is an alternative to that represented in document GRRF/2015/9 and GRRF-79-19.

The overall aim of the study is to propose policy options concerning the use of tyres for improvement of traffic safety. Centrally to this, is the idea that end users need to make the correct assessment in relation to the tyre condition in order to achieve a level of safety as high as possible. Within this context, the tyre condition is considered in relation to technical elements (tyre inflation pressure, tyre tread depth, tyre damage, tyre age, and meteorological influences) and one information element (driver awareness). The study addresses the topics of tyre usage and the impact on road safety (which are the potential safety improvements related to tyre usage from a technical perspective) and how can road users be supported to use tyres that have a better safety performance by policy options.

This document contains the consolidated text of proposals for the 03 series of
amendments to Regulation No. 51, as adopted by GRB at its sixtieth and sixty-first
sessions:
- ECE/TRANS/WP.29/GRB/58, para. 5, based on ECE/TRANS/WP.29/GRB/2014/5,
as amended by Annex III to ECE/TRANS/WP.29/GRB/58;1 and
- ECE/TRANS/WP.29/GRB/59, paras. 8-10, based on ECE/TRANS/WP.29/GRB/2015/3 and Corr.1, as amended by Annex III to ECE/TRANS/WP.29/GRB/59.

Following a decision of GRB, this consolidated text will be submitted to the June
2015 session of WP.29 for consideration and possible adoption.

Working draft version pursuant to the 3rd REG58-QRTV informal working group session.

Reference prepared by the WP.29 secretariat

“Cleaned-up” version of the draft text as developed during the 3rd session of the QRTV informal group.

Proposal to update the reference to the latest version of the ISO 10844 and to introduce transitional provisions for the shift of the test track requirements from ISO 10844: 1994 to ISO 10844: 2014.

Proposal to allow vehicles to be run at idle during the test procedures and to change the minimum sound level requirement for vehicles of category M and N and motorcycles of a power greater than 7 kW from 93 dB to 87 dB.

Proposal to introduce a calculated engine speed (in addition to measured engine speed) for MT vehicles and for continuously variable transmission (CVT)/automatic transmission (AT) with locked gear mechanism into UN Regulation No. 41 for the tests in Annex 3 and Annex 7 (Additional sound emission provisions – ASEP)

Proposal for a new time measurement accuracy for instrumentation involved in the rolling resistance method (Annex 6 of the UN Regulation) and to restore transitional provisions incorrectly deleted by Supplement 6 to the 02 series of amendments. The proposal also updates the test-track references to the recently published ISO 10844:2014.

Proposal to update the reference to the latest version of ISO 10844 and to introduce transitional provisions for the shift of the test track requirements from ISO 10844: 1994 to ISO 10844: 2014.

Further refinements to the 02 series of amendments prepared by the Informal Working Group on UN Regulations Nos. 51 and 59. This submission proposes to clarify the amended text of document WP.29/2015/4 which was adopted during the March 2015 WP.29 session.
