level specified by the manufacturer. Shock absorbers shall operate normally.
6.1.5                                Fuel, battery acid and other combustible, explosive or corrosive materials may be substituted by other materials provided that the conditions prescribed in clause 6.1.1 above are met.
6.1.6                                The impact area shall consist of concrete or other rigid material.
6.2                                      TEST PROCEDURES (see figure 2)
6.2.1                                The vehicle shall be placed on a platform in order to be rolled over on one side. This side shall be specified by the manufacturer.
6.2.2                                The position of the vehicle on the platform shall be such that when the platform is horizontal:
6.2.2.1                          the axis of rotation is parallel to the longitudinal axis of the vehicle,
6.2.2.2                          the axis of rotation is 0-200 mm from the vertical step between the two levels,
6.2.2.3                          the axis of rotation is 0-l00 mm from the side of the tyre at the widest axle,
6.2.2.4                          the axis of rotation is 0-l00 mm below the horizontal starting plane on which the tyres stand, and
6.2.2.5                          the difference between the height of the horizontal starting plane and the horizontal lower plane on which impact takes place shall be not less than 800 mm.
6.2.3                                Means shall be provided to prevent the vehicle moving along its longitudinal axis.
6.2.4                                The test apparatus shall prevent the tyres from sliding sideways in the direction of roll-over by means of side walls.
6.2.5                                The test apparatus shall ensure the simultaneous lifting of the axles of the vehicle.
6.2.6                                The vehicle shall be tilted without rocking and without dynamic effects until it rolls over. The angular velocity shall not exceed 5 degrees per second (0.087 rad/sec).
6.2.7                                High-speed photography, deformable templates or other suitable means shall be used to determine that the requirement of clause 2.1 has been met. This shall be verified by the test facility at not less than two positions, nominally at the front and rear of the passenger compartment, the exact positions being chosen to ensure that compliance is demonstrated in the worts position(s).
         Templates shall be fixed to substantially non-deformable parts of the structure, e.g. the floor of the vehicle.

7.                                          ROLL-OVER TEST ON A BODY SECTION
7.1                                      TEST CONDITIONS
7.1.1                                The body section shall represent a section of the unladen vehicle.
7.1.2                                The geometry of the body section, the axis of rotation and the position of the centre of gravity in the same vertical and lateral directions shall be representative of the complete vehicle.
7.1.3                                The mass of the body section, expressed as a percentage of the unladen mass of the vehicle, shall be specified by the manufacturer.
7.1.4                                The energy to be absorbed by the body section, expressed as a percentage of the total
