Annex 7, Calculations (mass), §
PROPOSAL:
Mass of the individual vehicle
The selected test masses of vehicles H and L TML and TMH as determined in paragraph of Annex 4 shall be used as input for the interpolation method.
The mass of the optional equipment m_o shall be calculated for the individual vehicle according to the following equation:
m_o = ∑_(i=1)^n▒〖∆m_i 〗 (2229)
where:
m_o is the difference in mass between the individual vehicle and TM_L, kg;
∆m_ii is the mass of an individual option i on the vehicle (∆m_i ∆m_iis positive for an option that adds mass with respect to TM_L and vice versa), kg;
n is the number of options that are different between the individual vehicle and test vehicle L.
TASK: Approval of deletion of the text in red.
Approved by the experts (AP) and incorporated accordingly in the GTR.

OPEN POINT: : DC asks whether a wind tunnel must be certified and if so, by who? C. Lueginger requested to pass onto the appropriate experts for comments.
EXPERT PROPOSAL: : Experts L. Bigi, A. Feucht, C. Lueginger propose to delete "certified".
STATUS AS OF : Entered on in the GTR as an expert proposal.

9. Annex 7, Calculations (mass)
Expert approval required
Proposal from Drafting Co.: Inserting this between and of Annex 7 would make that Annex more coherent.
Annex 7, Calculations (mass)
5. Calculation of cycle energy demand
Basis of the calculation is the target speed trace given in discrete time sample points t i between t start and t end . In case of the Class 2 and Class 3 cycles, t start =0 second and t end =1800 seconds. For a specific cycle phase, t start and t end shall be taken from Annex 1.
For the calculation, each time sample point is interpreted as a time period. The duration ∆t of these periods depends on the sampling frequency (1 second for 1 Hz, 0.5 seconds for 2 Hz or 0.1 seconds for 10 Hz).
TASK: Is the paragraph OK as is?

10. Confirmation
Annex 7, Calculations, §3.1.2.
The mass M of gaseous compounds emitted by the vehicle during the test shall be determined by obtaining the product of the volumetric concentration of the gas in question and the volume of the diluted exhaust gas with due regard for the following densities under the reference conditions of  K (0 °C)   and  kPa:  
STATUS AS OF : Following corrections submitted by T. Adam:
Comment from Drafting Co.: As a rule in chemistry, the "1" in a chemical compound is not included, e.g. C1H1.85 is written simply as CH1.85. T. Adam supports the above chemical annotation using "1".

Annex 7, Calculations, § &
OPEN POINT: : The entire paragraph deals with road load calculations, which paragraphs and do not. If agreed, they should be renumbered as and ?
