            Subpart F--Side Impact Dummy 50th Percentile Male
 
Sec. 572.43  Lumbar spine and pelvis.

    (a) When the pelvis of a fully assembled dummy (SA-SID-M001A 
revision B, dated September 12, 1996, (incorporated by reference; see 
Sec. 572.40) is impacted laterally by a test probe conforming to 
Sec. 572.44(a) at 14 fps in accordance with paragraph (b) of this 
section, the peak acceleration at the location of the accelerometer 
mounted in the pelvis cavity in accordance with Sec. 572.44(c) shall be 
not less than 40g and not more than 60g. The acceleration-time curve for 
the test shall be unimodal and shall lie at or above the +20g level for 
an interval not less than 3 milliseconds and not more than 7 
milliseconds.
    (b) Test Procedure. (1) Adjust the dummy legs as specified in 
Sec. 572.44(f). Seat the dummy on a seating surface as specified in 
Sec. 572.44(h) with the limbs extended horizontally forward.
    (2) Place the longitudinal centerline of the test probe at the 
lateral side of the pelvis at a point 3.9 inches vertical from the 
seating surface and 4.8 inches ventral to a transverse vertical plane 
which is tangent to the back of the dummy's buttocks.
    (3) Align the test probe so that at impact its longitudinal 
centerline coincides with the line formed by intersection of the 
horizontal and vertical planes perpendicular to the midsagittal plane 
passing through the designated impact point.
    (4) Adjust the dummy so that its midsagittal plane is vertical and 
the rear surfaces of the thorax and buttocks are tangent to a transverse 
vertical plane.
    (5) Impact the pelvis with the test probe so that at the moment of 
impact the probe's longitudinal centerline falls within 2 degrees of the 
line specified in paragraph (b)(3) of this section.
    (6) Guide the test probe during impact so that it moves with no 
significant lateral, vertical or rotational movement.
    (7) Allow a time period of at least 2 hours between successive tests 
of the pelvis.
