# §572.188. Pelvis.

- (a) **The pelvis (175-6000) is part of the torso assembly shown in drawing 175-0000.** The pelvis is equipped with a pubic symphysis load sensor in conformance with [§ 572.189(f)](/cfr/49/572.189.md?p=f) and mounted as shown in drawing (175-0000 sheet 4). When subjected to tests procedures specified in [paragraph (b)](#b) of this section, the pelvis assembly shall meet performance requirements specified in [paragraph (c)](#c) of this section.
- (b) **Test procedure.**
  - (1) Soak the dummy assembly (175-0000) without suit (175-8000) and shoulder foam pad (175-3010) as specified in [§ 572.189(n)](/cfr/49/572.189.md?p=n);
  - (2) The dummy is seated as specified in Figure U6 in appendix A to this subpart;
  - (3) The pelvis impactor is the same as specified in [§ 572.189(a)](/cfr/49/572.189.md?p=a);
  - (4) The impactor is guided, if needed, so that at contact with the pelvis its longitudinal axis is within ±0.5 degrees of a horizontal plane and perpendicular to the midsagittal plane of the dummy and the centerpoint on the impactor's face is within 5 mm of the center of the H-point in the pelvis, as shown in Figure U6 in appendix A to this subpart;
  - (5) The impactor impacts the dummy's pelvis at 4.3 ±0.1 m/s.
  - (6) Time zero is defined in [§ 572.189(k)](/cfr/49/572.189.md?p=k).
- (c) **Performance criteria.**
  - (1) The impactor force (probe acceleration multiplied by its mass) shall be not less than 4,700 N and not more than 5,400 N, occurring between 11.8 ms and 16.1 ms from time zero;
  - (2) The pubic symphysis load, measured with load cell specified in [§ 572.189(f)](/cfr/49/572.189.md?p=f) shall be not less than 1,230 N and not more than 1,590 N occurring between 12.2 ms and 17.0 ms from time zero.
