572.189—Instrumentation and test conditions.

(a) The test probe for lateral shoulder, thorax without arm, abdomen, and pelvis impact tests is the same as that specified in § 572.36(a) and the impact probe has a minimum mass moment of inertia in yaw of 9,000 kg-cm 2, a free air resonant frequency not less than 1,000 Hz and the probe's end opposite to the impact face has provisions to mount an accelerometer with its sensitive axis collinear with the longitudinal axis of the probe. All hardware attached directly to the impactor and one-third ( 1/3) of the mass of the suspension cables must be included in the calculations of the total impactor mass. The sum mass of the attachments and 1/3 cable mass must not exceed 5 percent of the total pendulum mass. No suspension hardware, suspension cables, or any other attachments to the test probe, including velocity vane, shall make contact with the dummy during the test.

(b) Accelerometers for the head, the thoracic spine, and the pelvis conform to specifications of SA572-S4.

(d) Linear position transducer for the thoracic rib conforms to SA572-S69.

(e) Load sensors for the abdomen conform to specifications of SA572-S75.

(f) Load sensor for the pubic symphysis conforms to specifications of SA572-77.

(g) Load sensor for the lumbar spine conforms to specifications of SA572-76.

(h) Instrumentation and sensors conform to the Recommended Practice SAE J-211 (Mar. 1995)—Instrumentation for Impact Test unless noted otherwise.

(i) All instrumented response signal measurements shall be treated to the following specifications:

(1) Head acceleration—Digitally filtered CFC 1000;

(2) Neck and lumbar spine rotations—Digitally filtered CFC 180;

(3) Neck and lumbar spine pendulum accelerations—Digitally filtered CFC 60;

(4) Pelvis, shoulder, thorax without arm, and abdomen impactor accelerations—Digitally filtered CFC 180;

(5) Abdominal and pubic symphysis force—Digitally filtered at CFC 600;
