Document:	Revision 1 \| Amendment 1
Corresponds to:	00 series of amendments \| Supplement 1 (Entered into force on 25 Sep 2020)
Based on:	Document WP.29/2020/18 Proposal to clarify test procedures allowing non-random selection of parameter combinations and provide for protrusion requirements for Blind Spot Information Systems (BSIS) external elements. Document WP.29-180-05 Proposal to correct values presented in document WP.29/2020/18 and clarification of “first point of information” application in assessment of BSIS.

Regulation:	UN Regulation No. 117 \| Tire Rolling Sound Emissions, Adhesion on Wet Surfaces, and Rolling Resistance
Document:	Revision 4 \| Amendment 3
Corresponds to:	02 series of amendments \| Supplement 11 (Entered into force on 25 Sep 2020)
Based on:	Document WP.29/2020/6 Proposal for an amendment to complement the content of working document GRVA/2018/5. The proposal includes amendments to: The Standard Reference Test Tyre (SRTT) denominations Remove the discrimination between the two Class C3 tyres Clarify that there are no C3 tyres in the scope of this UN Regulation “not marked with speed symbol” Align Annex 6 with the most recent amendments made to standard ISO 28580 Define “standard deviation” as appropriate in the text Clarify that, in the cases of C2 and C3 tyres, the “Reference (test) pressure” and the value “Pr” correspond to the indication of the inflation pressure which is always marked on the sidewall Use “repeatable” instead of references to “reproducibility” Update test report forms Include the date on which the new proposed supplement of UN Regulation No. 117 will apply Improve the description of the evaluation of the rolling sound emission test Correct the figure in Annex 2, Appendix 2, and Update cross references pursuant to paragraph renumbering.
