arm of the measuring apparatus is not changed during a particular operation. Each operation starts from the vertical position.

Paragraph 3.

The 25.4 mm dimension means the measurement from a horizontal plane passing through the "H" point to the horizontal tangent to the lower profile of the headform.

      1. GENERAL REQUIREMENTS
          1.            Except as provided in clause 1.2, when the area of the instrument panel that is within the 'Head Impact Area' is impacted in accordance with clause 1.3 by a 6.8 kg, 165 mm diameter head form at a relative velocity as specified in clause 1.1.1 or clause 1.1.2 below, the deceleration of the head form shall not exceed 80 times the acceleration due to gravity continuously for more than 3 milliseconds.
              1.      24.1 km/h for all vehicles other than those specified in clause 1.1.2
              2.      19.2 km/h for vehicles which meet the requirements of ADR 69/... for frontal impact using an inflatable supplementary restraint system for the front outboard passenger seating position.
          2.            The requirements of clause 1.1 do not apply to:
              1.      Console assemblies;
              2.      Areas less than 127 mm inboard from the juncture of the instrument panel attachment to the body side inner structure;
              3.      Areas closer to the windscreen juncture than those statically contactable by the head form with the windscreen in place;
              4.      Areas outboard of any point of tangency on the instrument panel of a 165 mm diameter head form tangent to and inboard of a vertical longitudinal plane tangent to the inboard edge of the steering wheel; or
              5.      Areas below any point at which a vertical line is tangent to the rearmost surface of the instrument panel.
          3.            Test Procedures For Section 1.
              1.      Tests shall be performed as described in SAE document J921 - "Instrument Panel Laboratory Impact Test Procedure", June 1965, using the specified instrumentation or instrumentation that meets the performance requirements specified in SAE document J977 - "Instrumentation for Laboratory Impact Test", November 1966,  except that:
                    1.            the origin of the line tangent to the instrument panel surface shall be a point on a transverse horizontal line through a point 127 mm horizontally 'Forward' of the 'Seating Reference Point' of the front outboard passenger seating position; displaced vertically an amount equal to the rise which results from either a 127 mm 'Forward' adjustment of the 'Seat' or
