(a)

Ensure testing within the entire vehicle floor contact surface defined for individual i-Size seating positions;

| (b) | Be rigidly fixed to the SFAD so that the forces applied to the SFAD will directly induce test forces into the vehicle floor, without reduction of the reactive test forces due to damping within or deformation of the support leg test device itself. |
