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 the test.

2.2. The test vehicle shall be prepared as follows:

       2.2.1. tyres shall be inflated to the pressure prescribed by the manufacturer.

       2.2.2. the suspension system of the vehicle shall be blocked, i.e. the axles, the springs and the suspension elements of the vehicle shall be fixed in relation to the bodywork.  The floor height above the horizontal tilting platform shall be according to the manufacturer's
       specification for the vehicle, dependent on whether it is loaded to unladen kerb mass or total vehicle mass.

       2.2.3. every door and opening window of the vehicle shall be closed but not locked.

       2.3. The rigid sections of an articulated vehicle may be tested separately or in combination.

       2.3.1. For testing the articulated sections as a combination, the sections of the vehicle shall  be fixed to each other in such a way that,

       2.3.1.1. there is no relative movement between them during the roll-over process.

       2.3.1.2. there is no significant change in mass distribution and centre of gravity positions.

       2.3.1.3. there is no significant change in the strength and deformation capability of the superstructure.

       2.3.2. For testing the articulated sections separately, the single-axle sections shall be attached to an artificial support which keeps them in fixed relation to the tilting platform during its movement from the horizontal to the point of roll-over.  This support shall meet the following requirements:

       2.3.2.1. it shall be fixed to the structure in such a way that it does not cause either reinforcement or extra additional load to the superstructure.

       2.3.2.2. it shall be constructed so that it does not suffer any deformation which could change the direction of the rollover of the vehicle.

       2.3.2.3. its mass shall be equal to the mass of those elements, parts of the articulated joint, which nominally belong to the section being tested, but which are not placed on it (e.g. turntable and its floor, handholds, rubber sealing curtains, etc.).

       2.3.2.4. its centre of gravity shall have the same height as the common centre of gravity of those parts which are listed in paragraph 2.3.2.3.

       2.3.2.5. it shall have an axis of rotation  parallel to the longitudinal axis of the multi-axle section of the vehicle, and passing through the points of  contact of the tyres of that section.

       3.1. The rollover test is a very rapid,
