(1) The parts enlisted in “Parts/Drawing List, Part 572Subpart T, Hybrid III 10 Year Old Child Test Dummy (HIII-10C), March, 2015” (incorporated by reference, see § 572.170),

(a) The head assembly for this test consists of the complete head (drawing 420-1000), a six-axis neck transducer (drawing SA572-S11, included in drawing 420-0000), or its structural replacement (drawing 420-383X), and 3 accelerometers (drawing SA572-S4, included in drawing 420-0000) (all incorporated by reference, see § 572.170).

(a) The neck assembly for the purposes of this test consists of the assembly of components shown in drawing 420-2000 (incorporated by reference, see § 572.170).

(a) The thorax consists of the part of the torso assembly designated as the upper torso (drawing 420-3000) (incorporated by reference, see § 572.170).

(a) The test objective is to determine the stiffness of the molded lumbar assembly (drawing 420-4100), abdominal insert (drawing 420-4300), and chest flesh assembly (drawing 420-3560) on resistance to articulation between the upper torso assembly (drawing 420-3000) and lower torso assembly (drawing 420-4000) (all incorporated by reference, see § 572.170).

(a) The knee assembly for the purpose of this test is the part of the leg assembly shown in drawing 420-5000 (incorporated by reference, see § 572.170).

(1) The test probe for thoracic impacts is of rigid metallic construction, concentric in shape, and symmetric about its longitudinal axis. It has a mass of 6.89 ±0.05 kg (15.2 ±0.1 lb) and a minimum mass moment of inertia of 2040 kg-cm 2 (1.81 lbf-in-sec 2) in yaw and pitch about the CG. One-third ( 1/3) of the weight of the suspension cables and their attachments to the impact probe is included in the calculation of mass, and such components may not exceed five percent of the total weight of the test probe. The impacting end of the probe, perpendicular to and concentric with the longitudinal axis, is at least 25.4 mm (1.0 in) long, and has a flat, continuous, and non-deformable 121 ±0.25 mm (4.76 ±0.01 in) diameter face with a maximum edge radius of 12.7 mm (0.5 in). The probe's end opposite to the impact face has provisions for mounting of an accelerometer with its sensitive axis collinear with the longitudinal axis of the probe. No concentric portions of the impact probe may exceed the diameter of the impact face. The impact probe has a free air resonant frequency of not less than 1000 Hz, which may be determined using the procedure listed in the PADI (incorporated by reference, see § 572.170).
