etc. where fitted, shall also be included.
8.2.3                                Every door and opening window of the body section shall be closed and latched but not locked. Windows and glazed bulkheads or screens may be glazed or unglazed at the applicant's discretion.
8.2.4                                Where appropriate seats may also be included, at the option of the manufacturer, in their normal position in relation to the structure of the body section. The normal fixings and joints between all members and attachments shall be incorporated. The backrests if adjustable shall be in their most upright position and the height of the seats if adjustable shall be the highest position.
8.2.5                                The side of the body section to be impacted shall be at the discretion of the manufacturer. Where more than one body section is required to be tested both shall be impacted on the same side.
8.2.6                                High speed photography, deformable templates or other suitable means shall be used to determine that the requirement specified in clause 2.1 has been met. Templates shall be fixed to a substantially non-deformable part of the structure.
8.2.7                                The body section to be tested shall be firmly and securely attached to the mounting frame through the cross-bearers or parts which replace these in such a way that no significant energy is absorbed in the support frame and its attachments during the impact.
8.2.8                                The pendulum shall be released from such a height that it strikes the body section at a speed of between 3 and 8 m/s.
8.3                                      DESCRIPTION OF THE PENDULUM
8.3.1                                The striking face of the pendulum shall be made of steel, or plywood 20 mm ±  5 mm thick, and the mass of the pendulum shall be evenly distributed. Its striking face shall be rectangular and flat, having a width of not less than the width of the body section being tested and a height of not less than 800 mm. Its edges shall be rounded to a radius of curvature of not less than l5 mm.
8.3.2                                The body of the pendulum shall be rigidly attached to two rigid bars. The axis of the bars shall be not less than 3,500 mm from the geometric centre of the body of the pendulum.

         8.4                                      REQUIREMENTS FOR THE DISTRIBUTION OF THE MAIN ENERGY ABSORBING PARTS OF THE SUPERSTRUCTURE

8.4.1                                A sufficient number of tests shall be carried out for the test facility to be satisfied that the complete vehicle meets the requirements of clause 2.1. This shall not necessarily require more than one test.

8.4.2                                Calculations based on data obtained from a test on a body section may be used to demonstrate the acceptability of another body section which is not identical with the body section already
