Revised floor flex test 29 August 2010
The FIA carry out load tests to check whether a car's floor flexes beyond the permitted 5mm (yellow highlighted area) under a 200kg load. The test, which uses a piston in the centre of the floor, was introduced at the 2007 Spanish Grand Prix following the controversy surrounding Ferrari's 'moveable' floor device. Stricter front-wing flex tests have been introduced here at Spa and at the next round in Italy a stricter floor test will be added. Whilst the same weight will be used, the test will be applied to the side of the floor too. It will also be prohibited to run a section of plank less than 100cm in length.
