              4.                                    "Superstructure" means the load-bearing components of the bodywork as defined by the manufacturer, containing those coherent parts and elements which contribute to the strength and energy absorbing capability of the bodywork, and preserve the residual space in the rollover test.
              5.                                    "Body section" means a section containing at least two identical vertical pillars on each side representative of a part or parts of the structure of the vehicle.

              6.                                    "Total energy" means the energy assumed to be absorbed by the complete structure of the vehicle. This may be determined as shown in clause 8.

              1.                                    The superstructure of the vehicle shall be of sufficient strength to ensure that during and after it has been subjected to one of the methods of test or calculation prescribed in clause 3.:
              2.                                    No displaced part of the vehicle intrudes into the residual space, as specified in clause 4., and
              3.                                    No part of the residual space projects outside the deformed structure.
              4.                                    The requirements of paragraph 2.1. above shall apply to the vehicle including all its structural parts, members and panels and all projecting rigid parts such as luggage racks, ventilation equipment, etc. However, bulkheads, partitions, rings or other members reinforcing the superstructure of the vehicle and fixed appliances such as bars, kitchenettes or toilets shall be ignored for the purposes of paragraph 2.1.
              5.                                    In the case of an articulated vehicle each part of the vehicle shall comply with the requirements specified in paragraph 2.1. above.

              1.                                    Each type of vehicle shall be verified according to one of the following methods at the discretion of the manufacturer or according to an alternative method approved by the 'Administrator ':
                  1.                              A roll-over test on a complete vehicle in accordance with the procedure set out in clause 6.;
                  2.                              A roll-over test on a body section or sections representative of a complete vehicle in accordance with clause 7.;
                  3.                              A pendulum test on a body section or sections in accordance with clause 8.; or
                  4.                              A verification of strength of superstructure by calculation in accordance with clause 9.
                  5.                              If the methods prescribed in paragraphs 3.1.2., 3.1.3. or 3.1.4. cannot take account of a significant variation between one section of the vehicle and another, for example an air-conditioning installation on the roof, additional test methods or calculations shall be conducted.
