1. Proposal for handling CoP (Conformity of Production)
CO2 Transmission expert group

2. CoP on component level - Transmission
CoP only if Options 2 and/or 3 have been used for certification.
Option 2 and 3 certified loss values are controlled with a simplified option 2 measurement to verify the conformity of production (CoP).
Supplier needs to show the correlation between the certified values and the CoP-values (regarding temperatures, oil quality, oil level, installation angle, sensor accuracy, run-in effect, etc.).

3. Measurement of CoP-values
Measurements are done at the two highest gears for the transmission.
Input speed; the certification speed point closest to 50 % of the maximum rated speed of the transmission.
Each measured CoP-value must not be larger than + 25 % of the corresponding certified loss value.
One transmission of each certified transmission variant (sub-group) is tested per year and CoP-values are stored
If a “worst case”-principle is used when reporting certified loss values, the same principle needs to be used for the CoP-measurements (meaning that the transmission used with a higher loss value for the certification also needs to be used for the CoP).

4. Handling of changes vs. CoP-values
Hardware changes: if considered having negligible influence on power losses: new loss measurements not required.
Still, each measured CoP-value must not be larger than + 25 % of the corresponding (original) certified loss value.
