The minimum distance between the adjacent rear wing sections at any longitudinal vertical plane was checked on car numbers 03, 14, 16 and 55.
It was confirmed for car numbers 03, 14, 16 and 55 that any vertical cross section of bodywork normal to the car centre line and situated in the volumes defined in Article 3.5.7 form one tangent continuous curve on its external surface with a radius no less than 75mm.
The concave radius of sections of the two rear wing elements which are in contact with the external air stream was checked on car numbers 03, 14, 16 and 55.

The lap energy release and recovery limits were checked on all cars.
The MGU-K power limits were checked on all cars.
The maximum MGU-K speed was checked on all cars.
The maximum MGU-K torque was checked on all cars.
The maximum MGU-H speed was checked on all cars.
The session type has been confirmed for all cars.
Chassis FIA checksum was checked on all cars taking part in the race.

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 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 MD5 checksum of the PCU8 (dash board display) used on the car matched the configuration lodged with the FiA prior to the qualifying session.
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.
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 checked.
The total fuel mass consumed by all cars during the race was checked.
A fuel sample was taken from car number 16.
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 16.
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.
