ISO 8645 Mopeds — Light-alloy wheels — Test method Specifies methods Wheel Radial Load Fatigue Testing for determining the reliability of lightalloy road wheels for mopeds under normal use stress. Applies to wheels for mopeds with two or three wheels, as defined in ISO 3833, of the following types: unit construction wheels; composite construction wheels. It include radial fatigue testing, cornering fatigue testing, impact testing, and more. These tests simulate real-world driving conditions and help to ensure that the wheels can withstand the stresses and strains of regular use over time. So, By adhering to the standards outlined in the standard, manufacturers can ensure that their passenger car wheels are safe and reliable for use on the road.

Requirements of ISO 8645

Radial fatigue testing: This test is used to evaluate the resistance of the wheel to repeated bending loads applied in a radial direction. The test measures the number of cycles the wheel can withstand before failure occurs.

Cornering fatigue testing: This test evaluates the ability of the wheel to withstand repeated bending loads applied in a lateral direction. The test measures the number of cycles the wheel can withstand before failure occurs.

Impact testing: This test evaluates the ability of the wheel to withstand an impact from a curb or other obstacle. The test measures the force required to cause visible damage to the wheel.

Coating adhesion testing: This test evaluates the adhesion of the coating to the wheel. The test measures the force required to peel off the coating from the wheel surface.

Dynamic cornering fatigue testing: This test evaluates the ability of the wheel to withstand repeated bending loads applied in a lateral direction while the wheel is rotating at high speeds. The test measures the number of cycles the wheel can withstand before failure occurs.

Dynamic radial fatigue testing: This test evaluates the ability of the wheel to withstand repeated bending loads applied in a radial direction while the wheel is rotating at high speeds. The test measures the number of cycles the wheel can withstand before failure occurs.
