# §572.116. Instrumentation and test conditions.

- (a) The test probe for lateral thoracic and pelvis impact tests are the same as those specified in [§ 572.44(a)](/cfr/49/572.44.md?p=a).
- (b) Accelerometer mounting in the thorax is the same as specified in [§ 572.44(b)](/cfr/49/572.44.md?p=b).
- (c) Accelerometer mounting in the pelvis is the same as specified in [§ 572.44(c)](/cfr/49/572.44.md?p=c).
- (d) Head accelerometer mounting is the same as specified in [§ 572.36(c)](/cfr/49/572.36.md?p=c).
- (e) Neck transducer mounting is the same as specified in [§ 572.36(d)](/cfr/49/572.36.md?p=d).
- (f) Instrumentation and sensors used must conform to SAE Recommended Practice J211, March 1995, “Instrumentation for Impact Tests.”
- (g) The mountings for the spine, rib and pelvis accelerometers shall have no resonance frequency within a range of 3 times the frequency range of the applicable channel class.
- (h) Limb joints of the test dummy shall be set at the force between 1 to 2 g's, which just supports the limb's weight when the limbs are extended horizontally forward. The force required to move a limb segment does not exceed 2 g's throughout the range of the limb motion.
- (i) Performance tests must be conducted at a temperature between 20.6 and 22.2 degrees C. (69 to 72 degrees F.) and at a relative humidity between 10 percent and 70 percent after exposure of the dummy to those conditions for a period of at least four (4) hours.
- (j) For the performance of tests specified in [§ 572.114](/cfr/49/572.114.md) and [§ 572.115](/cfr/49/572.115.md), the dummy is positioned the same as specified in [§ 572.44(h)](/cfr/49/572.44.md?p=h).
