The minimum distance between the adjacent rear wing sections at any longitudinal vertical plane was checked on car numbers 27, 10 and 14.
It was confirmed for car numbers 27, 10 and 14 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 27, 10 and 14.
The front and rear brake air duct dimensions were checked on car numbers 27, 10 and 14.
It was checked that no classified car exceeded 80 km/h when leaving the formation grid prior to the start of the race.

The plenum temperature was checked on all cars.
The oil consumption was checked on car numbers 05, 07, 11, 27, 10 and 14.
The ES state of charge on-track limits were checked on car numbers 44, 77, 05, 07, 03, 31, 27, 10, 20 and 14.
The lap energy release and recovery limits were checked on car numbers 44, 77, 05, 07, 03, 31, 27, 10, 20 and 14.
It was checked on car numbers 44, 77, 05, 07, 03, 33, 11, 31, 27, 55, 10, 08, 20, 14, 02, 09 and 16 that the MGU-K was not used below 100 km/h at the start.
The MGU-K power limits were checked on car numbers 44, 77, 05, 07, 03, 31, 27, 10, 20 and 14.
The maximum MGU-K torque was checked on car numbers 44, 77, 05, 07, 03, 31, 27, 10, 20 and 14.
The maximum MGU-K speed was checked on car numbers 44, 77, 05, 07, 03, 31, 27, 10, 20 and 14.
The maximum MGU-H speed was checked on car numbers 44, 77, 05, 07, 03, 31, 27, 10, 20 and 14.
It was checked on car numbers 44, 77, 05, 07, 03, 33, 11, 31, 27, 55, 18, 35, 10, 14, 02 and 09 that the ES was not charged while the car was stationary in the pits.
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 03.
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 10.
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.
