annually to the requirements of ASTM E4.
Levelton & Associates
proof test three 7" High and three 9” High Wheel Chocks described

The load was applied perpendicular to the tire bearing surface and the chock base was restrained.
All Wheel Chocks withstood the proof load without failure or permanent deformation.
