After the second free practice session:
Car number 43 was weighed.
The fuel pressure of all cars during the second free practice session was checked.
The logged pressure within the engine cooling system during the second free practice session was checked on all cars.
The maximum turbocharger speed was checked on all cars.
The DC sensor code and calibration checksums were checked on all cars.
The on-track ES state of charge was checked on all cars.
The ERS recharge limits were checked on all cars.
The maximum MGU-K power limits were checked on all cars.
Chassis FIA checksum was checked on all cars.
The rear brakes pressure control was checked on car numbers 12, 44, 05 and 11.
The custom software versions were checked on all cars.
The SECU software versions were checked on all cars.
The tyres used by all drivers during the sessions today have been checked.
A fuel sample was taken from car number 55.
The results of fuel analyses show that the fuels were the same as ones, which had been approved for use by the relevant competitors prior to the Competition. Further the density change of the fuel samples taken today was within the permitted limits.
An engine oil sample was taken from car number 55.
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 Competition.
