of the dummy and measured according to paragraph 5.2.4. of annex 3.
5.2.  The tibia index is calculated on the basis of the bending moments (Mx and My) measured according to paragraph 5.1. by the following expression:
 where:

 MX = bending moment about the x axis
 MY = bending moment about the y axis
 (MC)R = critical bending moment and shall be taken to be 225 Nm
 FZ = compressive axial force in the z direction
 (FC)Z = critical compressive force in the z direction and shall be taken to be 35,9 kN and
 MR=
 The tibia index is calculated for the top and the bottom of each tibia; however, FZ may be measured at either location. The value obtained is used for the top and bottom TI calculations. Moments MX and MY are both measured separately at both locations.
6.  PROCEDURE FOR CALCULATING THE VISCOUS CRITERIA (V * C) FOR HYBRID III DUMMY
6.1.  The viscous criterion is calculated as the instantaneous product of the compression and the rate of deflection of the sternum. Both are derived from the measurement of sternum deflection.
6.2.  The sternum deflection response is filtered once at CFC 180. The compression at time t is calculated from this filtered signal as:
 The sternum deflection velocity at time t is calculated from the filtered deflection as:
 where D(t) is the deflection at time t in metres and  t is the time interval in seconds between the measurements of deflection. The maximum value of  t shall be 1,25 x 10-4 seconds. This calculation procedure is shown diagrammatically below:

ARRANGEMENT AND INSTALLATION OF DUMMIES AND ADJUSTMENT OF RESTRAINT SYSTEMS

1. ARRANGEMENT OF DUMMIES
1.1. Separate seats
 The plane of symmetry of the dummy shall coincide with the vertical median plane of the seat.
1.2. Front bench seat
1.2.1. Driver
 The plane of symmetry of the dummy shall lie in the vertical plane passing through the steering wheel centre and parallel to the longitudinal median plane of the vehicle. If the seating position is determined by the shape of the bench, such seat shall be regarded as a separate seat.
1.2.2. Outer passenger
 The plane of symmetry of the dummy shall be symmetrical with that of the driver dummy relative to the longitudinal median plane of the vehicle. If the seating position is determined by the shape of the bench, such seat shall be regarded as a separate seat.
1.3. Bench seat for front passengers (not including driver)
 The planes of symmetry of the dummy shall coincide with the median planes of the seating positions defined by the manufacturer.
2. INSTALLATION OF DUMMIES
2.1. Head
 The transverse instrumentation platform of the head shall be
