French to English Tech/Engineering Automotive / Cars & Trucks quality plan inspection

This comes in a table where the contractor sets out the quality controls for all the equipment it uses ((marking it NF compliant etc.).
In the section for vehicles, which includes cars, cranes and trucks, they are marked "CONTROLE CF". Does anyone expert know if this is a technical check (eddy current testing for instance) or a more general abbreviation in quality that I've not connected with? Please?
