Cockpit rim tests

In Simple Terms

The FIA tests the cockpit rim (the edge around the driver's cockpit) to ensure it's strong enough to protect drivers. They apply a powerful sideways force equivalent to about 5 tons of pressure on a small 50mm area, and the rim must barely bend (less than 10mm) and snap back to its original shape when released.

• A 50mm diameter pad simulates impact force on the cockpit rim at a specific location
• The rim must withstand 50kN (50,000 Newtons) of sideways force without structural failure
• Maximum deformation during the test is limited to 10mm to prevent driver injury
• The rim must return to nearly its original shape, with permanent deformation under 1.0mm, ensuring structural integrity
