              3. Assembly of the dummy

              3.1. Head-neck

              3.1.1. The required torque on the half-spherical screws for assembly of the neck is 10 Nm.

              3.1.2.  The head-upper neck load cell assembly is mounted to the head-neck interface plate of the neck by four screws.

              3.1.3. The neck-thorax interface plate of the neck is mounted to the neck-bracket by four screws.

              3.2. Neck-shoulder-thorax

              3.2.1. The neck-bracket is mounted to the shoulder block by four screws.

              3.2.2. The shoulder-block is mounted to the top-surface of the thoracic spine box by three screws.

              3.3. Shoulder-arm

              3.3.1.  The arms are mounted to the shoulder clavicles by means of a screw and an axial bearing. The screw shall be tightened to obtain a 1 - 2 g holding force of the arm on its pivot.

              3.4. Thorax-lumbar spine-abdomen

              3.4.1. The mounting direction of rib modules in the thorax shall be adapted to the required impact side.

              3.4.2. A lumbar spine adapter is mounted to the T12 load cell or load cell replacement at the lower part of the thoracic spine by two screws.

              3.4.3. The lumbar spine adapter is mounted to the top of the lumbar spine with four screws.

              3.4.4. The mounting flange of the central abdominal casting is clamped between the lumbar spine adapter and the lumbar spine top plate.

              3.4.5. The location of the abdominal force transducers shall be adapted to the required impact side.

              3.5. Lumbar spine-pelvis-legs

              3.5.1. The lumbar spine is mounted to the sacrum block cover plate by three screws. In case of using the lower lumbar spine load cell four screws are used.

              3.5.2. The lumbar spine bottom plate is mounted to the sacrum block of the pelvis by three screws.

              3.5.3. The legs are mounted to the upper femur bracket of the pelvis hip joint assembly by a screw.

              3.5.4. The knee and ankle links in the legs can be adjusted to obtain a 1 - 2 g holding force.

              4. Main characteristics

              4.1.  Mass

              4.1.1. The masses of the main dummy components are presented in table 2 of this annex.
