Scope:

The purpose of this test is to evaluate the axial strength of the nut seat of wheels intended for use on passenger cars, light trucks, and multipurpose vehicles. In addition, a minimum contact area is recommended to ensure enough strength for the rotational force in tightening a nut against the nut seat. While this test ensures the minimum strength of the nut seat, the wheel must also have a degree of flexibility. This flexibility, as well as bolt tension, are important to maintain wheel retention.

Rationale:

1. Table 1 description is editorial, purpose to change from “deformance test” to “deformation test” for clarity. 2. Table 2 and 3 has the M14 x 2.0 size added and treated same as M14 x 1.5 and 9/16 - 18. The M14 X 2.0 is new to the wheel industry. 3. Test report for 3.3 Deformation test and 3.4.2 yield strength test is added for uniformity of reporting. 4. SAE J2530 is added to SAE Publications to inform aftermarket wheel manufacturers. 5. 3.3.2 b. a suspension of loading is noted at twice (2X) minimum load at elastic limit. The suspension defines when the test can be suspended. 6. Table 2 is renamed from Yield load to Minimum load at yield for clarification.
