                     Subpart B--50th Percentile Male
 
Sec. 572.10  Limbs.

    (a) The limbs consist of the assemblies shown as numbers SA 150 
M070, SA 150 M071, SA 150 M080, and SA 150 M081 in Figure 1 and conform 
to the drawings subtended by these numbers.
    (b) When each knee is impacted at 6.9 ft/sec. in accordance with 
paragraph (c) of this section, the maximum force on the femur shall be 
not more than 2500 pounds and not less than 1850 pounds, with a duration 
above 1000 pounds of not less than 1.7 milliseconds.
    (c) Test procedure: (1) Seat the dummy without back support on a 
surface as specified in Sec. 572.11(i) that is 17.30.2 
inches above a horizontal surface, oriented as specified in 
Sec. 572.11(i), and with the hip joint adjustment at any setting between 
1g and 2g. Place the dummy legs in planes parallel to

its midsagittal plane (knee pivot centerline perpendicular to the 
midsagittal plane) and with the feet flat on the horizontal surface. 
Adjust the feet and lower legs until the lines between the midpoints of 
the knee pivots and the ankle pivots are at any angle not less than 2 
degrees and not more than 4 degrees rear of the vertical, measured at 
the centerline of the knee pivots.
    (2) Reposition the dummy if necessary so that the rearmost point of 
the lower legs at the level one inch below the seating surface remains 
at any distance not less than 5 inches and not more than 6 inches 
forward of the forward edge of the seat.
    (3) Align the test probe specified in Sec. 572.11(a) so that at 
impact its longitudinal centerline coincides within 2 deg. 
with the longitudinal centerline of the femur.
    (4) Impact the knee with the test probe moving horizontally and 
parallel to the midsagittal plane at the specified velocity.
    (5) Guide the probe during impact so that it moves with no 
significant lateral, vertical, or rotational movement.
