annex 7 to this Regulation.
    6.2. The safety-belts or other restraint systems, which are specified for the vehicle, shall be used.  Belts should be of an approved type, conforming to Regulation No. 16 or to other equivalent requirements and mounted on anchorages conforming to Regulation No. 14 or to other equivalent requirements.
    6.3. The safety-belt or restraint system shall be adjusted to fit the dummy in accordance with the manufacturer's instructions; if there are no manufacturer's instructions, the height adjustment shall be set at middle position; if this position is not available, the position immediately below shall be used.

    7. MEASUREMENTS TO BE MADE ON THE SIDE IMPACT DUMMY
    7.1. The readings of the following measuring devices are to be recorded.
    7.1.1. Measurements in the head of the dummy
     The resultant triaxial acceleration referring to the head centre of gravity. The head channel instrumentation shall comply with ISO 6487:1987 with:
      CFC:  1000 Hz, and
      CAC:  150 g
    7.1.2. Measurements in the thorax of the dummy
     The three thorax rib deflection channels shall comply with ISO 6487:1987
      CFC:  1000 Hz
      CAC:  6 mm
    7.1.3. Measurements in the pelvis of the dummy
     The pelvis force channel shall comply with ISO 6487:1987
      CFC:  1000 Hz
      CAC:  15 kN
    7.1.4. Measurements in the abdomen of the dummy
     The abdomen force channels shall comply with ISO 6487:1987
      CFC:  1000 Hz
      CAC:  5 kN

    DETERMINATION OF PERFORMANCE DATA

    The required results of the tests are specified in paragraph 5.2. of this Regulation.

    l. HEAD PERFORMANCE CRITERION (HPC)
     When head contact takes place, this performance criterion is calculated for the total duration between the initial contact and the last instant of the final contact.
     HPC is the maximum value of the expression:
     where a is the resultant acceleration at the centre of gravity of the head in metres per second per second divided by 9.81 recorded versus time and filtered at channel frequency class 1000 Hz; t1 and t2 are any two times between the initial contact and the last instant of the final contact.

    2. THORAX PERFORMANCE CRITERIA
    2.1. Chest deflection:  the peak chest deflection is the maximum value of deflection on any rib as determined by the thorax displacement transducers, filtered at channel frequency class 180 Hz.
    2.2. Viscous criterion:  the peak viscous response is the maximum value of VC on any rib which is calculated from the instantaneous product of the relative thorax compression related to the half thorax and the velocity of compression derived by differentiation of the compression, filtered at channel frequency class 180 Hz.  For the purposes of this calculation the standard width of the half thorax rib cage is 140 mm.
