the axis of rotation;

       1.4.3. the wheel supports at the other axles shall be adjusted so that the vertical longitudinal centre plane (VLCP) of the vehicle shall be parallel to the axis of rotation.

       1.5. The tilting platform shall be constructed to prevent the vehicle moving along its longitudinal axis.

       1.6. The impact area of the ditch shall have a horizontal, uniform, dry and smooth concrete surface.

       2. Preparation of test vehicle

       2.1. The vehicle to be tested need not be in a fully finished, "ready for operation" condition. Generally, any alteration from the fully finished condition is acceptable if the basic features and behaviour of the superstructure are not influenced by it.  The test vehicle shall be the same as its fully finished version in respect of the following:

       2.1.1. the position of the centre of gravity, the total value of vehicle mass (unladen kerb mass, or total effective vehicle mass where restraints are fitted) and the distribution and location of masses, as declared by the manufacturer.

       2.1.2. all of those elements which – according to the manufacturer - contribute to the strength of the superstructure shall be installed in their original position (see Annex 4 to this Regulation).

       2.1.3. elements, which do not contribute to the strength of the superstructure and are too valuable to risk damage (e.g. drive chain, dashboard instrumentation, driver's seat, kitchen equipment, toilet equipment, etc.) can be replaced by additional elements equivalent in mass and method of installation.  These additional elements must not have a reinforcing effect on the strength of superstructure.

       2.1.4. fuel, battery acid and other combustible, explosive or corrosive materials may be substituted with other materials provided that the conditions of paragraph 2.1.1. are met.

       2.1.5. In the case where occupant restraint devices are part of the vehicle type, a mass shall be attached to each seat fitted with an occupant restraint following one of these two methods, at the choice of the manufacturer:

2.1.5.1.  First  method: That mass shall be:

2.1.5.1.1  50 per cent of the individual occupant mass (Mmi) of 68 kg,

       2.1.5.1.2.  placed to have its centre of gravity 100 mm above and 100 mm forward of the R point of the seat as defined in Regulation No. 21, Annex 5.

2.1.5.1.3.  fixed rigidly and securely so that it does not break away during the test.

       2.1.5.2                 Second method:  That mass shall be

       2.1.5.2.1 an anthropomorphic ballast with a mass of 68 kg and shall be restrained with a 2 point safety-belt.  The ballast must allow guiding and positioning for safety-belts.

2.1.5.2.2. placed to have its centre of gravity and dimensioning according to figure A5.2.

       2.1.5.2.3.        fixed rigidly and securely so that it does not break away during
