Requirement of FMVSS No.223 - Rear underrun protective devices (RUPDs)Apply force to the guard in a forward direction such that the displacement rate of the force
application device is constant and not less than 2 cm and not more than 9 cm per minute until the force specified for each test location below has been exceeded, or until the displacement of
the force application device has reached 130 mm +0, -5 mm, whichever comes first.
