The rear brakes pressure control was checked on all cars.
The brake temperature warnings were checked on all cars.
The race start data of all cars have been checked.
Single clutch paddle use for the race start has been checked on all cars.
The MGU-K use at the race start was checked on all cars.
It was checked on all cars that the ES was not charged while the car was stationary in the pits.
It was checked that no classified car exceeded 80 km/h when leaving the formation grid prior to the start of the race.
It was verified on all cars that the PCU dash board display configuration was not changed in Parc Fermé.
The tyre starting pressures of all cars during the race were checked.
The tyres used by all drivers during the race today have been checked.
It was checked that all cars did not exceed 15000 rpm during the race.
The fuel pressure of all cars during the race was checked.
Fuel flow meter calibration checksums were checked on all cars.
The instantaneous fuel mass flow of all cars was checked.
The fuel temperature of all cars was checked.
A fuel sample was taken from car number 05.
The fuel samples have been checked for density and analysed by gas chromatography.
The results of all the fuel analyses show that the fuels were the same as ones, which had been approved for use by the relevant competitors prior to the Event. Further the density change of the fuel samples taken today was within the permitted limits.
An engine oil sample was taken from car number 05.
The engine oil samples have been analysed by FTIR spectroscopy and viscometry. The results of the FTIR analyses show that the sampled oils were consistent with reference engine oil samples which had been approved for use by the relevant competitors prior to the Event.
All car weights and the items checked were found to be in conformity with the 2021 FIA Formula One Technical Regulations.
