Report on the development of Amendment 4 to GTR 15. Amendment 4 is part of the second phase development of the GTR mandated to:

1. Introduce definitions of response time, delay time and rise time harmonized with those in GTR Nos. 4 and 11
2. Introduce improvements to the gear shifting procedures
3. Ensure consistency in the use of the terms accuracy, precision, resolution, tolerance, repeatability and deviation
4. Address bi-fuel and bi-fuel gas vehicles in accordance with UN R83
5. Clearly define the appropriate positioning of payload mass (25 kg plus the mass of vehicle load)
6. Correct terminology such as “classes of rolling resistance coefficients”
7. Correct minor spelling and/or punctuation mistakes, and restructuring some paragraphs
8. orrect some equations and to make them all consistent with Word’s use of mathematical symbols
9. Exclude all Rechargeable Electric Energy Storage Systems (REESSs) that do not contribute to vehicle propulsion from monitoring
10. etter define the purity of certain gases such as nitrogen and synthetic air
11. Define more specifically the difference in mass of CO2 during charge sustaining between the test with the highest and lowest positive and negative electric energy charge

Proposal of amendments to the light vehicle emissions GTR (WLTP) pursuant to the “phase 2” mandate of the WLTP informal group. This proposal is also available in a marked-up version with changes tracked in word and pdf formats.

Proposal for amendments to GTR 19 pursuant to the “Phase 2” mandate of the WLTP informal group. This proposal addresses the evaporative emissions test procedure for sealed fuel tank systems. Versions of this proposal highlighting the changes are available in word and pdf formats.

Proposal from the Evaporative Task Force of the Informal Working Group (IWG) on the Worldwide harmonized Light vehicles Test Procedure (WLTP) to improve the text of the draft Amendment 1 to GTR 19 with regard to evaporative emissions from fuel tanks.

Revised proposal for Amendment 4 to GTR 15 from the WLTP informal group.

Revised proposal from the WLTP informal group pursuant to GRPE-76 discussions for Amendment 4 under the Phase 2 development of GTR 15.

Consolidated version of GTR 15 including the draft Amendment 4 as approved by the Working Party on Pollution and Energy. The amended GTR will be considered for adoption during the June 2018 World Forum session.

Amendment 1 to UN Global Technical Regulation No. 19 on Evaporative emission test procedure for the Worldwide harmonized Light vehicles Test Procedures (WLTP EVAP) as approved by the Working Party on Pollution and Energy. The amendment will be considered for adoption during the June 2018 session of the World Forum.
