Of the original 150+ slides, appx. 30 were left requiring further processing, e.g.

Definitions Annex 4 Road Load (new text, road load family, text improvements, missing

terms in some equations) Annex 5 Test Equipment (improved diagrams, consistency in the use of SI units,

some paragraphs on additional pollutants) Annex 6 Test Procedure (comments from Japan on testing vehicles H and L,

regenerating systems, net heating value) Annex 7 Calculations (mass of an individual vehicle, missing explanation of terms

in some equations) Annex 8 (OVC-HEV tests, NOVC-HEV tests, utility factors)

The content of those slides which were approved were integrated into the GTR.

Since the Brussels meeting, another 40 slides have been added to be processed.

The latest version of the GTR incorporating the results of the 3-day Brussels meeting was uploaded to the UN ECE server as: WLTP-10-04e-GTR Version 03.04.2015 This version contains all tracking changes, as they are necessary for the UN ECE

Secretariat's work

WLTP-10-34e

For the Drafting Subgroup and its work tomorrow, three documents have been uploaded to the UN ECE server:

The GTR, version 03.04.2015 including all tracking changes.

The GTR, version 03.04.2015 incorporating all GTR corrections (see next page), and material confirmed since the first days of the GTR. As a result, many tracking change bubbles have been eliminated, making the GTR more readable. This was requested during the Brussels meeting.

The 70+ slides mentioned on the previous page.

Types of corrections incorporated into the GTR: elimination of "must", use of the word "will", use of

sample/samples/sampling/sampled, formatting, spelling, spacing, paragraph/equation/figure numbers were checked, use of weighing and weighting.

BTW: according to the UN ECE, "must" may not be used, only "shall". "Shall" is for obligations and "may" for options. However, the GTR uses "must" on at least one occasion. These

uses can be justified.

Future work

Processing those items adopted during WLTP IWG meeting 10. Processing the unfinished slides. Incorporating decisions made by the VPSD group once they have

been approved by the appropriate experts. Deciding on future Drafting Subgroup meetings:
