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 brake temperature warnings were checked on car numbers 44 and 05.
The plenum temperature was checked on all cars.
The oil consumption was checked on car numbers 44, 77, 05, 07, 33, 11, 31, 18, 55 and 08.
The MGU-K use at the race start was checked on car numbers 44, 77, 05, 07, 33, 11, 31, 18, 55 and 08.
It was checked on car numbers 44, 77, 05, 07, 33, 11, 31, 18, 55 and 08 that the ES was not charged while the car was stationary in the pits.
The ES state of charge on-track limits were checked on car numbers 44, 77, 05, 07, 33, 11, 31, 18, 55 and 08.
The lap energy release and recovery limits were checked on car numbers 44, 77, 05, 07, 33, 11, 31, 18, 55 and 08.
The maximum MGU-K speed was checked on car numbers 44, 77, 05, 07, 33, 11, 31, 18, 55 and 08.
The maximum MGU-K torque was checked on car numbers 44, 77, 05, 07, 33, 11, 31, 18, 55 and 08.

The maximum MGU-H speed was checked on car numbers 44, 77, 05, 07, 33, 11, 31, 18, 55 and 08.
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 flow of all cars was checked.
The total fuel mass used by every classified car during the race was checked.
The fuel temperature of all cars was checked.
A fuel sample was taken from car number 33.
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 44.
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 above items checked were found to be in conformity with the 2018 FIA Formula One Technical Regulations.
