box (part No. 4a) is made of steel. On the rear surface a steel spacer and curved, polyurethane (PU)-resin, back plate is mounted (part No. 4b).

              2.5.4. The top surface of the thoracic spine box is inclined 5° backwards.

              2.5.5. At the lower side of the spine box a T12 load cell or load cell replacement (part No. 4j) is mounted.

              2.5.6. A rib module (part No. 4c) consists of a steel rib bow covered by a flesh-simulating open-cell polyurethane (PU) foam (part No. 4d), a linear guide system assembly (part No. 4e) linking the rib and spine box together, a hydraulic damper (part No. 4f) and a stiff damper spring (part No. 4g).

              2.5.7. The linear guide system (part No. 4e) allows the sensitive rib side of the rib bow (part No. 4d) to deflect with respect to the spine box (part No. 4a) and the non-sensitive side. The guide system assembly is equipped with linear needle bearings.

              2.5.8. A tuning spring is located in the guide system assembly (part No. 4h).

              2.5.9. A rib displacement transducer (part No. 4i) can be installed on the spine box mounted part of guide system (part No. 4e) and connected to the outer end of the guide system at the sensitive side of the rib.

              2.6. Arms

              2.6.1. The arms are shown as part No. 5 in Figure 1 of this annex.

              2.6.2. The arms have a plastic skeleton covered by a polyurethane (PU) flesh representation with a polyvinylchloride (PVC) skin. The flesh representation consists of a high density polyurethane (PU) moulding upper part and a polyurethane (PU) foam lower part.

              2.6.3. The shoulder-arm joint allows for discrete arm positions at 0, 40 and 90° setting with respect to the torso axis.

              2.6.4. The shoulder-arm joint allows for a flexion-extension rotation only.

              2.7. Lumbar spine

              2.7.1. The lumbar spine is shown as part No. 6 in Figure 1 of this annex.

              2.7.2. The lumbar spine consists of a solid rubber cylinder with two steel interface plates at each end, and a steel cable inside the cylinder.

              2.8. Abdomen

              2.8.1. The abdomen is shown as part No. 7 in Figure 1 of this annex.

              2.8.2. The abdomen consists of a rigid central part and a foam covering.

              2.8.3. The central part of the abdomen is a metal casting (part No. 7A). A cover plate is mounted on top of the casting.

              2.8.4. The covering (part No. 7b) is made of polyurethane (PU) foam. A curved slab of rubber filled with lead-pellets is integrated in the foam covering at both sides.

              2.8.5. Between the foam covering and the rigid casting at each side of the abdomen, either three force transducers (part No. 7c) or
