Rotating-bending test
› An endurance test that simulates the lateral forces experienced in a curve.
Rolling test
› Simulates the forces that act on the wheel when the vehicle is driving in a straight line.
Radial impact test
› Primarily tests the strength of the wheel’s rim well.
Ridge test
› Simulates driving over a curb, over potholes, etc.
Testing the material characteristics
› A tensile strength test and a crystallographic image determine the energy absorption characteristics of the rim flange to ensure a high level of casting quality.
CASS test
› A copper accelerated acetic acid spray solution tests the hardness and integrity of the paintwork.
Climate and condensation test
› The wheel paintwork is exposed to extreme heat and high humidity.
X-ray and computer tomography tests
› These tests detect any small inclusions or gas bubbles in the wheel.
