3. (b) Light vehicles: Global Technical Regulations Nos. 15 (WLTP) and 19 (WLTP EVAP)
|
14. The Chair of the IWG on the Worldwide harmonized Light vehicles Test Procedures (WLTP) reported on the ongoing activities (GRPE-76-25). He confirmed that the IWG on WLTP would need some additional time to finalize all Phase 2 activities due to the complex and heavy workload. The Chair of GRPE noted that the mandate of the IWG on WLTP had been extended until December 2019.

Report on the development of Amendment 4 to GTR 15. Amendment 4 is part of the second phase development of the GTR mandated to: - Introduce definitions of response time, delay time and rise time harmonized with those in GTR Nos. 4 and 11
- Introduce improvements to the gear shifting procedures
- Ensure consistency in the use of the terms accuracy, precision, resolution, tolerance, repeatability and deviation
- Address bi-fuel and bi-fuel gas vehicles in accordance with UN R83
- Clearly define the appropriate positioning of payload mass (25 kg plus the mass of vehicle load)
- Correct terminology such as “classes of rolling resistance coefficients”
- Correct minor spelling and/or punctuation mistakes, and restructuring some paragraphs
- orrect some equations and to make them all consistent with Word’s use of mathematical symbols
- Exclude all Rechargeable Electric Energy Storage Systems (REESSs) that do not contribute to vehicle propulsion from monitoring
- etter define the purity of certain gases such as nitrogen and synthetic air
- 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

19. The expert from EC, leading the task force on the transposition of WLTP into the 1958 Agreement, GRPE-76-24 on the activities of his group with the development of three alternatives for the construction of a UN Regulation on WLTP, which were presented to the IWG on International Whole Vehicle Type Approval (IWVTA). He recalled the task force’s intention to proceed with a new series of amendments (08) of the existing Regulations Nos. 83 on emissions, including, e.g. Real Driving Emissions (RDE) and that would refer to the new UN Regulation on WLTP to gain approval for tests Types 1 and 4.
20. GRPE discussed the possible alternatives to structure the future UN Regulation on WLTP to address regional specificities. GRPE decided to request the secretariat to consult the Office of Legal Affairs (OLA) as noted in the Appendix of GRPE-76-24.
