This is an extract from the standard

5 STRUCTURAL INTEGRITY
5.1 Structural integrity When tested in accordance with Appendix C, a vehicle ramp shall
not show any sign of a break or fracture. Permanent deformation shall not exceed 2% of the
ramp height.
5.2 Overload test When tested in accordance with Appendix D, a vehicle ramp shall be
tested with a force not less than 3 times the nominated capacity in accordance with
Clause 3.5 and shall not break or fracture, or permanently deform by more than 5% of the
ramp height.

In the structural integrity test, the ramp is subjected to a load 1.5 times the nominated capacity. In the overload test, the ramp is subjeted to a load 3 times the nominated capacity, or until the ramp fails.
