A status report was given by Cova Astorga (doc. WLTP‐DTP‐10‐11). Much progress has been made regarding the measurement methodology and in the GTR drafting. NO/NOx will be measured by all labs. N2O and NH3 will be measured by some labs. The AP Group is confident to have sufficient validation data for NO/NOx measurement. For further components further measurements will likely be necessary.
