the manufacturer and agreed by the Technical Service.

In the case of vehicles in categories M2 and N2, this force must be equal to 10 times the mass of the complete seat; for categories M3 and N3 it shall be equal to 6.6 times the mass of the complete seat.

6.4.5.                         Test in configuration of a special-type belt

6.4.5.1.                   A test load of 1350 ± 20 daN shall be applied to a traction device (see annex 5, figure 2) attached to the belt anchorages of such a safety-belt by means of a device reproducing the geometry of the upper torso strap or straps.

6.4.5.2.                   At the same time, a tractive force of 1350 ± 20 daN shall be applied to a traction device (see annex 5, figure 3) attached to the two lower belt anchorages.

6.4.5.3.                   In the case of vehicles of categories other than M1 and N1, this test load shall be 675 ± 20 daN,  except  that  for  M3  and  N3  vehicles  the  test  load  shall be 450 ± 20 daN.

         6.4.6.                         Test in the case of rearward-facing seats

6.4.6.1.                   The anchorage points shall be tested according to the forces prescribed in paragraphs 6.4.1., 6.4.2. or 6.4.3., as appropriate. In each case the test load shall correspond to the load prescribed for M3 or N3 vehicles.

6.4.6.2.                   The test load shall be directed forward in relation to the seating position in question, corresponding to the procedure prescribed in paragraph 6.3.

6.5.                               In the case of a group of seats as described in paragraph 1. of annex 7, the dynamic test of annex 7 can be performed, at the option of the car manufacturer, as an alternative to the static test prescribed in paragraphs 6.3. and 6.4.

         6.6.                               Static test requirements.

6.6.1.                         The strength of the ISOFIX anchorage systems shall be tested applying the forces, as prescribed in paragraph 6.6.4.3., to the static force application device (SFAD) with ISOFIX attachments well engaged.

In case of ISOFIX top tether anchorage an additional test shall be performed as prescribed in paragraph 6.6.4.4.

All the ISOFIX positions of a same seat row, which can be used simultaneously, shall be tested simultaneously.

6.6.2.                         The test may be carried out either on a completely finished vehicle or on sufficient parts of the vehicle so as to be representative of the strength and rigidity of the vehicle structure.

Windows and doors may be fitted or not and closed or not.

Any fitting normally provided and likely to contribute to the vehicle structure may be fitted.

The test may be restricted to the ISOFIX position relating to only one seat or group of seats on the condition that:

            a)         The ISOFIX position concerned have the same
