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.
67. Agenda item 4.8.1, Regulation No. 117, document ECE/TRANS/WP.29/2013/55, add at the end:
Annex 4, the title, insert the reference to footnote 1 and footnote 1, to read:
“1 The specifications for the test site reproduced in this annex are valid until the end of the period indicated in paragraph 12.9.”
16. The expert from ETRTO introduced ECE/TRANS/WP.29/GRB/2013/5, drafted in cooperation with the experts from Poland and the United Kingdom, proposing to update the test track requirements to ISO 10844:2011 as a supplement to the UN Regulation rather than a new series of amendments. He stated that the new test track with tighter tolerances would maintain the same nominal noise behaviour and that its introduction as a new series of amendments was not justified (GRB-57-02). The experts from France endorsed the proposal and stated that technical variations introduced by the new track would not justify a new series of amendments. The experts from Italy and Japan also endorsed ECE/TRANS/WP.29/GRB/2013/5.
17. GRB finally adopted ECE/TRANS/WP.29/GRB/2013/5 (superseding ECE/TRANS/WP.29/GRB/2013/2, ECE/TRANS/WP.29/GRB/2012/15 and ECE/TRANS/WP.29/GRB/2012/18) as reproduced in Annex II to this report. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration and vote at their June 2013 sessions as draft Supplement 4 to the 07 series of amendments to UN Regulation No. 117. Moreover, GRB agreed that extensions of type approvals, granted by using the test track in accordance to ISO 10844:1994, may be carried out with the test track built in accordance with ISO 10844:2011, taking into account that this last would not negatively affect type approval noise test results.
