- (a)The test probe for shoulder, lateral thorax, and pelvis-acetabulum impact tests is the same as that specified in 49 CFR 572.137(a) except that its impact face diameter is 120.70 ±0.25 mm and it has a minimum mass moment of inertia of 3646 kg-cm 2.
- (b)The test probe for the lateral abdomen impact test is the same as that specified in 572.137(a) except that its impact face diameter is 76.20 ±0.25 mm and it has a minimum mass moment of inertia of 3646 kg-cm 2.
- (c)The test probe for the pelvis-iliac impact tests is the same as that specified in 49 CFR 572.137(a) except that it has a rectangular flat impact surface 50.8 × 88.9 mm for a depth of at least 76 mm and a minimum mass moment of inertia of 5000 kg-cm 2.
- (d)Accelerometers for the head, the thoracic spine, and the pelvis conform to specifications of SA572-S4.
- (e)Rotary potentiometers for the neck-headform assembly conform to SA572-S51.
- (f)Instrumentation and sensors conform to the Recommended Practice SAE J-211 (March 1995), Instrumentation for Impact Test, unless noted otherwise.
- (g)All instrumented response signal measurements shall be treated to the following specifications:
- (1)Head acceleration—digitally filtered CFC 1000;
- (2)Neck-headform assembly translation-rotation—digitally filtered CFC 60;
- (3)Neck pendulum, T1 and T12 thoracic spine and pelvis accelerations—digitally filtered CFC 180;
- (4)Neck forces (for the purpose of occipital condyle calculation) and moments—digitally filtered at CFC 600;
- (5)Pelvis, shoulder, thorax and abdomen impactor accelerations—digitally filtered CFC 180;
- (6)Acetabulum and iliac wings forces—digitally filtered at CFC 600;
- (7)Shoulder, thorax, and abdomen deflection—digitally filtered CFC 600.
- (h)Mountings for the head, thoracic spine and pelvis accelerometers shall have no resonant frequency within a range of 3 times the frequency range of the applicable channel class;
- (i)Leg joints of the test dummy are set at the force between 1 to 2 g, which just support the limb's weight when the limbs are extended horizontally forward. The force required to move a limb segment does not exceed 2 g throughout the range of the limb motion.
- (j)Performance tests are conducted, unless specified otherwise, at any temperature from 20.6 to 22.2 degrees C. (69 to 72 degrees F.) and at any relative humidity from 10% to 70% after exposure of the dummy to those conditions for a period of 4 hours.
- (k)Coordinate signs for instrumentation polarity shall conform to the Sign Convention For Vehicle Crash Testing, Surface Vehicle Information Report, SAE J1733, 1994-12 (refer to § 572.191(a)(5)).
