vehicle shall undergo a test in accordance with Annex 4 to this Regulation.

              5.1.1. The test will be carried out on the driver's side unless asymmetric side structures, if any, are so different as to affect the performance in a side impact. In that case either of the alternatives in paragraph 5.1.1.1. or 5.1.1.2. below may be used by agreement between the manufacturer and Type Approval Authority.

              5.1.1.1. The manufacturer will provide the authority responsible for approval with information regarding the compatibility of performances in comparison with the driver's side when the test is being carried out on that side.

              5.1.1.2. The Type Approval Authority, if concerned as to the construction of the vehicle, will decide to have the test performed on the side opposite the driver, this being considered the least favourable.

              5.1.2. The Technical Service, after consultation with the manufacturer, may require the test to be carried out with the seat in a position other than the one indicated in paragraph 5.5.1. of Annex 4. This position shall be indicated in the test report.[4]

              5.1.3. The result of this test shall be considered satisfactory if the conditions set out in paragraphs 5.2. and 5.3. below are satisfied.

              5.2. Performance criteria

               Additionally, vehicles equipped with electric power train shall meet the requirements of paragraph 5.3.7. below. This can be met by a separate impact test at the request of the manufacturer and after validation by the Technical Service, provided that the electrical components do not influence the occupant protection performance of the vehicle type as defined in paragraphs 5.2.1. to 5.3.5. of this Regulation. In case of this condition the requirements of paragraph 5.3.7. shall be checked in accordance with the methods set out in Annex 4 to this Regulation, except paragraphs 6., 7. and Appendices 1 and 2. But the side-impact dummy shall be installed in the front seat on the impact side.

              5.2.1. The performance criteria, as determined for the collision test in accordance with the Appendix 1 to Annex 4 to this Regulation shall meet the following conditions:

              5.2.1.1. The head performance criterion (HPC) shall be less than or equal to 1,000; when there is no head contact, then the HPC shall not be measured or calculated but recorded as "No Head Contact."

              5.2.1.2. The thorax performance criteria shall be:

                  (a) Rib Deflection Criterion (RDC) less than or equal to 42 mm;

                  (b) Soft Tissue Criterion (VC) less or equal to 1.0 m/sec.

               For a transitional period of two years after the date specified in paragraph 10.2. of this Regulation the V * C value is not a pass/fail criterion for the approval testing, but this value has to be recorded in the test report and
