Sec. 572.86  Test conditions and dummy adjustment.

    (a) With the complete torso on its back lying on a horizontal 
surface and the neck assembly mounted and shoulders on the edge of the 
surface, adjust the neck such that the head bolt is lowered 0.40 
 0.05 inches (10  1 mm) after a vertically 
applied load of 11.25 pounds (50 N) applied to the head bolt is 
released.
    (b) With the complete torso on its back with the adjusted neck 
assembly as specified in Sec. 572.66(a), and lying on a horizontal 
surface with the shoulders on the edge of the surface, mount the head 
and tighten the head bolt and nut firmly, with the head in horizontal 
position. Adjust the head joint at the force between 1-2g, which just 
supports the head's weight.
    (c) Using the procedures described below, limb joints are set at the 
force between 1-2g, which just supports the limbs' weight when the limbs 
are extended horizontally forward:
    (1) With the complete torso lying with its front down on a 
horizontal surface, with the hip joint just over the edge of the 
surface, mount the upper leg and tighten hip joint nut firmly. Adjust 
the hip joint by releasing the hip joint nut until the upper leg just 
starts moving.
    (2) With the complete torso and upper leg lying with its front up on 
a horizontal surface, with the knee joint just over the edge of the 
surface, mount the lower leg and tighten knee joint firmly. Adjust the 
knee joint by releasing the knee joint nut until the lower leg just 
starts moving.
    (3) With the torso in an upright position, mount the upper arm and 
tighten firmly the adjustment bolts for the shoulder joint with the 
upper arm placed in a horizontal position. Adjust the shoulder joint by 
releasing the shoulder joint nut until the upper arm just starts moving.
    (4) With the complete torso in an upright position and upper arm in 
a vertical position, mount the forearm in a horizontal position and 
tighten the elbow hinge bolt and nut firmly. Adjust the elbow joint nut 
until the forearm just starts moving.
    (d) With the torso assembled in an upright position, the adjustment 
nut for the lumbar vertebrae is tightened until the spring is compressed 
to \2/3\ of its unloaded length.
    (e) Performance tests are conducted at any temperature from 66 to 78 
degrees F and at any relative humidity from 10 percent to 70 percent 
after exposure of the dummy to these conditions for a period of not less 
than four hours.
    (f) Performance tests of the same component, segment, assembly or 
fully assembled dummy are separated in time by a period of not less than 
20 minutes unless otherwise specified.
    (g) Surfaces of the dummy components are not painted except as 
specified in the part or in drawings incorporated by this part.
