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: - change measurement units for drum speed in Annex 7 from min-1 to km.h-1 to align the requirements with other tyre regulations;
- correct the wording from “speed category symbol” to “speed symbol” (as defined in para. 2.33);
- correct the wording from “load capacity index” to “load index” (as defined in para. 2.32);
- correct a reference to para. 3.2.13. of the Regulation in Annex 7, Appendix 1;
- correct a boundary value of load index in Annex 7, Appendix 1;
- 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.
