With the dummy’s jacket in place, seat the dummy on a flat, rigid, smooth, clean, dry,
horizontal surface. The seating surface must be at least 406 mm (16-in) wide and 406-mm
(16-in) deep, with a vertical section at least 406 mm (16 in) wide and 914-mm (36 in) high
attached to the rear of the seating fixture. The dummy’s midsagittal plane is vertical and
centered on the test surface.
Seat the dummy in the test fixture so that the torso is against the vertical surface of the
fixture (Figure 1).

Take the following measurements and record on Table V1. Verify that each measurement
meets the specification by indicating “Pass” or “Fail” in the far right column.
Chest Circumference (Y): With the jacket on, using a tape measure positioned 114 mm
(4.5”) below the top surface of the non-struck side shoulder, measure the chest
circumference.
Remove the chest jacket. Position the dummy against the vertical back plate so that
dummy is in contact with the surface. Level the top surface of the top rib guide laterally.
Extend the dummy’s neck so that the base of the skull is level side-to-side, within 0.5
degrees. The rear surface of the skull cap should be 43 +/- 3 mm (1.70 +/- 0.10 in) from the
vertical surface of the test fixture (parameter H). A 43-mm wide block mounted to the
vertical surface of the seat behind the head will aid in this process. In addition, a strap or
bungee cord may be placed around the forehead of the dummy to stabilize the head in this
position.
