2 Test sample
Only fully processed new wheels which are representative of wheels intended for the vehicle shall be used for the test. No wheel shall be used for more than one test.
3 Disc wheel dynamic cornering fatigue test
3.1 Test equipment
The test machine shall have a driven rotatable device whereby either the wheel rotates under the influence of a stationary and is subjected to a rotating bending moment. See Figure 1.
3.2 Procedure
3.2.1 Preparation
Clamp the rim of the wheel securely to the test fixture in accordance with Figure 1a) or 1b). The adaptor face of the test machine shall have equivalent mounting systems to those used on the vehicle.
