Proposal to amend Annex 7 (based on the documents ECE/TRANS/WP.29/GRRF/2015/39 and GRRF-80-16 from Slovakia) and Annex 10. This proposal would:

1. change measurement units for drum speed in Annex 7 from min-1 to km.h-1 to align the requirements with other tyre regulations;
2. correct the wording from “speed category symbol” to “speed symbol” (as defined in para. 2.33);
3. correct the wording from “load capacity index” to “load index” (as defined in para. 2.32);
4. correct a reference to para. 3.2.13. of the Regulation in Annex 7, Appendix 1;
5. correct a boundary value of load index in Annex 7, Appendix 1;
6. delete in paragraph 2.1 in Annex 7, the possibility to use the 2.0 m drum diameter to perform the endurance test.

In Annex 10, the proposal aligns the text with Annex 7 of UN R117, 02 series of amendments, Supplement 5.

Document GRRF/2015/39 proposes to change measurement units for drum speed from min-1 to km.h-1 to align the
requirements with other tyre regulations. This amendment proposal would clarify wording:
1. “speed category symbol” to “speed symbol”,
2. “load capacity index” to “load index”,
3. correct reference to para. 3.2.13. of the Regulation in Annex 7, Appendix 1, and
4. correct the boundary value of the load index in Annex 7, Appendix 1.

Document GRRF/2015/38 proposes to change the measurement units for drum speed from min-1 to km.h-1 in alignment with the requirements with other tyre regulations. This proposal would clarify a footnote reference by replacing “speed categories N or P” with “speed category symbols N or P”.
