be perpendicular to the final part of the run‑up track and shall be covered with plywood boards 19  1 mm thick.  At least 90 tonnes of earth shall be compressed behind the block of reinforced concrete.  The barrier of reinforced concrete and earth may be replaced by obstacles having the same front surface, provided that they give equivalent results.

        2.2. At the moment of impact the vehicle shall run free.  It shall reach the obstacle on a course perpendicular to the collision wall; the maximum lateral misalignment allowed between the vertical median line of the front of the vehicle and the vertical median line of the collision wall shall be  30 cm; at the moment of impact the vehicle shall no longer be subjected to the action of any additional steering or propelling device.  The speed on impact shall be between 48.3 km/h and 53.1 km/h.

        2.3. The fuel feed system shall be filled to at least 90 per cent of its capacity with fuel or an equivalent liquid.

TEST PROCEDURE FOR DEVICES INTENDED TO PROTECT THE OCCUPANTS
AGAINST DISPLACEMENT OF LUGGAGE

          1.  Test blocks

          Rigid blocks, with the centre of inertia in the geometric centre.

          Type 1

                          Dimensions:  300 mm x 300 mm x 300 mm
                          all edges and corners rounded to 20 mm

                          Mass:   18 kg

          Type 2

                          Dimensions:  500 mm x 350 mm x 125 mm
                          all edges and corners rounded to 20 mm

                          Mass:   10 kg

          2.  Test preparation

          2.1.  Test of seat-backs (see figure 1)

          2.1.1.  General requirements

          2.1.1.1.  At the option of the car manufacturer, parts whose hardness is lower than 50 Shore A can be removed from the tested seat and head restraint for the tests.

          2.1.1.2.  Two type 1 test blocks shall be placed on the floor of the luggage compartment.  In order to determine the location of the test blocks in the longitudinal direction, they shall first be positioned such that their front side contacts that part of the vehicle which constitutes the forward boundary of the luggage compartment and that their lower side rests on the floor of the luggage compartment.  They shall then be moved backwards and parallel to the longitudinal median plane of the vehicle until their geometrical centre has traversed a
