vehicle may be tested separately or in combination as described in Annex 5, paragraph 2.3, or in Annex 3, paragraph 2.6.7.

       5.6. Direction of rollover test

        The rollover test shall be carried out on that side of the vehicle which is more dangerous with respect to the residual space.  The decision is made by the technical service on the basis of the manufacturer's proposal, considering at least the following:

       5.6.1. the lateral eccentricity of the centre of gravity and its effect on the reference energy in the unstable, starting position of the vehicle, see paragraph 3.2.2.1;

       5.6.2. the asymmetry of the residual space, see paragraph 5.2.2

       5.6.3. the different, asymmetrical constructional features of the two sides of the vehicle, and the support given by partitions or inner boxes (e.g. wardrobe, toilet, kitchenette).  The side with the lesser support shall be chosen as the direction of the rollover test.

       6. MODIFICATION AND EXTENSION OF APPROVAL OF A VEHICLE TYPE

       6.1. Every modification of the approved vehicle type shall be advised to the Administrative Department which granted the type approval.  The Administrative Department may then either,

       6.1.1. agree that the modifications made are unlikely to have an appreciable effect and that in any case the modified vehicle type still complies with the requirements of this Regulation and constitutes part of a group of vehicle types together with the approved vehicle type; or

       6.1.2. require a further test report from the technical service responsible for conducting the tests to prove that the new vehicle type complies with the requirements of this Regulation and constitutes part of a group of vehicle types together with the approved vehicle type; or

6.1.3. refuse the extension of approval and require a new approval procedure to be carried out.
       6.2. The decisions of the Administrative Department and the technical service shall be based on the threefold criteria of the worst case:

       6.2.1. the structural criterion means whether the superstructure is changed or not (see Annex 4).  If no change, or the new superstructure is stronger, this is favourable.

       6.2.2. the energy criterion means whether the reference energy is changed or not.  If the new vehicle type has the same or smaller reference energy than the approved one, this is favourable.

       6.2.3. residual space criterion is based on the envelope surface of the residual space.  If the residual space of the new vehicle type is everywhere within the approved case residual space, this is favourable.

       6.3. If all three criteria described in paragraph 6.2. are changed favourably, the extension of the approval shall be granted without further investigation.

        If all of three answers are unfavourable, a new approval procedure is required.

        If the answers are mixed, further investigations (tests,
