it shall not degrade the transducer responses.
    2.2.2. The rigid barrier shall be either anchored in the ground or placed on the ground with, if necessary, additional arresting devices to limit its displacement.  A rigid barrier with load cells having different characteristics but giving results that are at least equally conclusive may be used.

    3. PROPULSION OF THE MOBILE DEFORMABLE BARRIER
     At the moment of impact the mobile deformable barrier shall no longer be subject to the action of any additional steering or propelling device.  It shall reach the obstacle on a course perpendicular to the collision barrier.  Impact alignment shall be accurate to within 10 mm.

    4. MEASURING INSTRUMENTS
    4.1. Speed
     The impact speed shall be 35 +2 -2 km/h.  The instrument used to record the speed on impact shall be accurate to within one per cent.
    4.2. Loads
     Measuring instruments shall meet the specifications set forth in ISO 6487-1987
     CFC for all blocks = 60 Hz
     CAC for blocks 1 and 3 = 120 kN
     CAC for blocks 4, 5 and 6 = 60 kN
     CAC for block 2 = 140 kN
    4.3. Acceleration
     The acceleration in the longitudinal direction shall be measured at a place not subject to bending.  The instrumentation shall comply with ISO 6487:1987 with the following specifications:
     CFC 1000 Hz (before integration)
     CFC 60 Hz (after integration)
     CAC 50 g

    5. GENERAL SPECIFICATION OF BARRIER
    5.1. The individual characteristics of each barrier shall comply with paragraph 1 of annex 5 and shall be recorded.

    6. GENERAL SPECIFICATION OF THE IMPACTOR TYPE
    6.1. The suitability of an impactor type shall be confirmed when the outputs from the six load cells each produce signals complying with the requirements indicated in annex 5, paragraph 2.2. to this Regulation when recorded.
    6.2. Impactors shall carry consecutive serial numbers including the date of manufacture.
