《GB/T 5909-2009商用车辆车轮性能要求和试验方法》由TC114（全国汽车标准化技术委员会）归口，主管部门为工业和信息化部。
本标准规定了商用车辆车轮的试验方法和性能要求。
本标准适用于商用车辆辐板式车轮、辐条式车轮和可拆卸式轮辋的车轮。

1 Scope

This standard specifies the test methods and performance requirements of commercial vehicle wheels.

This standard is applicable to the disc wheels, spoke wheels and wheels with demountable rim for commercial vehicles.

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. The mating surface of the test adaptor and wheel shall be free of excessive scoring and deformation, and excessive build-up of paint, dirt or foreign matter.
