On the grid it was checked that all cars had fitted their tyres when the "3-Minutes" signal was given.
On the grid it was checked that the top ten cars had fitted the tyres which they had used when doing their fastest lap in Q2.
On the grid the temperature of the LHS and RHS front and rear tyre was checked on car numbers 44, 05, 18 and 10.
On the grid the minimum tyre starting pressure of the LHS and RHS front and rear tyre was checked on all cars.

1) Bodywork around the front wheels 2) Front wing height and overhang 3) Rear wing height and overhang 4) Front and rear wing width 5) Rear wing configuration 6) Rear bodywork area 7) Rear winglet height 8) Skidblock thickness 9) Stepped bottom 10) Diffuser height 11) Diffuser area 12) Overall height 13) Overall width
The profile of the in Article 3.3.2 of the 2018 Formula One Technical Regulations prescribed front wing section was checked on car numbers 11, 31, 14, 09 and 16.
The minimum distance between the adjacent rear wing sections at any longitudinal vertical plane was checked on car numbers 11, 31, 14, 09 and 16.
It was confirmed for car numbers 11, 31, 14, 09 and 16 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 11, 31, 14, 09 and 16.
The front and rear brake air duct dimensions were checked on car numbers 11, 31, 14, 09 and 16.
It was checked that no classified car exceeded 80 km/h when leaving the formation grid prior to the start of the race.
The units locking status 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.
Single clutch paddle use for the race start has been checked on all cars.
The race start data of car number 77, 05, 07, 03, 33, 11, 31, 18, 35, 27, 55, 08, 20, 14, 02, 09 and 16 have been checked.
The plenum temperature was checked on all cars.
The oil consumption was checked on car numbers 05, 03, 11, 08, 09 and 16.
The brake temperature warnings were checked on car numbers 05, 07, 33, 11, 31, 08, 20 and 14.
The ES state of charge on-track limits were checked on car numbers 33, 11 and 14.
The lap energy release and recovery limits were checked on car numbers 33, 11 and 14.
The MGU-K power limits were checked on car numbers 33, 11 and 14.
The maximum MGU-K torque was checked on car numbers 33, 11 and 14.
The maximum MGU-K speed was checked on car numbers 33, 11 and 14.
The maximum MGU-H speed was checked on car numbers 33, 11 and 14.
It was checked on car numbers 44, 77, 05, 07, 03, 33, 11, 31, 18, 35, 27, 55, 28, 10, 08, 20, 02, 09 and 16 that the MGU-K was not used below 100 km/h at the start.
It was checked on car numbers 33, 11 and 14 that the ES was not charged while the car was stationary in the pits.
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.
The fuel temperature of all cars was checked.
The instantaneous fuel flow of all cars was checked.
Fuel flow meter calibration checksums were checked on all cars.
The total fuel mass used by every classified car 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 14.
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 2018 FIA Formula One Technical Regulations.
