Article C16.5.3
Fuel Conformity Testing
Chapter: C16
In Simple Terms
The FIA tests fuel samples from F1 cars using a scientific method called gas chromatography to make sure they match the approved fuel specification. Small differences due to fuel evaporation are allowed, but the FIA can always do additional testing if needed.
- Gas chromatographic technique is the official testing method for fuel conformity
- Fuel samples must match the FIA-approved fuel specification
- Minor evaporative losses during storage/transport are considered acceptable
- The FIA reserves the right to conduct further testing at any time
Official FIA Text
Fuel samples checked for conformity using gas chromatographic technique comparing with approved fuel. Samples differing only by evaporative loss considered compliant. FIA retains right to further testing.
