Editorial corrections from the WLTP informal to its original submission.

Proposal for inclusion of CoP requirements into global technical regulation No. 15 (Worldwide harmonized Light vehicles Test Procedures (WLTP)) and UN global technical regulation No. 19.

1. The text for this proposal is based on the CoP requirements in Section 4 of Annex I to European Commission Regulation (EU) 2017/1151, as last amended by Regulation (EU) 2018/1832.
2. The text has been edited to reflect the wording used in the GTR 15 and 19, and references to the applicable annexes and paragraphs have been revised.
3. The text is presented in the format and style of GTR, while containing all elements that will be needed for the UNR WLTP.
4. Editorial changes have been made to improve the text.
5. Issues that have to be discussed within the CoP TF are indicated in [text brackets].
6. Regional specific issues (such as for Europe on the OBFCM, eco-innovations, and family criteria for commercial vehicles etc.) are left out of this text, and will be added in a later stage.
7. The scope of vehicles is not specifically indicated in this text proposal, this is therefore identical to the scope and application specified for GTRs 15 and 19.
8. The final text proposal has to be in agreement with the outcome of discussions within the Transposition TF.
9. The administrative elements will be excluded from this text, to only reflect the technical elements for the GTRs.
