Merc may argue the TD does not specifically apply to their car issue.
Technical Directive TD039
A metric value is defined as a criterion for the extent of the oscillations. An analysis of how this parameter is determined is ongoing and will continue over the two practice sessions on Friday.
The so-called "Az signal" for the vertical acceleration during the up and down movements is transmitted directly to the FIA control unit. Scrutineers can see at any time how hard the car hits the road at high speeds.
It is still being discussed how the Az signal should be evaluated, whether peak values or average forces should be taken into account. The teams measuring these values for their own setup analysis are invited to share their methodology with the FIA.
The teams still don't know what the rule holders consider an acceptable value. Acceptable value will be determined before 3rd practice.
Test: Teams then need to determine the oscillations over three consecutive laps with DRS disabled at race speed. If there is a suspicion that the driver is deliberately driving slowly, the attempt is considered failed. The same applies when you close the gap on another car.
Once the FIA has determined a "safe set-up" for each individual vehicle, the ride height, spring rates and damper settings, and aerodynamic configuration may no longer be changed. Exceptions include weather changes, adjustments to cooling needs, tire pressures, front wing adjustment.
If a competitor wishes to return to a previously used setup, they must first demonstrate to the FIA that these adjustments meet safety criteria. All parameters such as vehicle height, suspension travel and the aerodynamic configuration must be submitted to the FIA in the voting sheets after the third practice session, together with the corresponding oscillation values.
If a competitor is not able to reach the FIA required limits and thus a safe setup, he must use the setup that is closest to the limits and then increase the rear ground clearance by another ten millimeters without changing the suspension travel or the aerodynamic configuration.
