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 1,350 ± 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 1,350 ± 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.
6.4.7. Test in the case of side-facing seats
6.4.7.1. The anchorage points shall be tested according to the forces prescribed in paragraph 6.4.3. for M3 vehicles.
6.4.7.2. The test load shall be directed forward in relation to the vehicle, corresponding to the procedure prescribed in paragraph 6.3. In the case that side-facing seats are grouped together on a basic structure, the safety-belt anchorage points of each seating position in the group shall be tested separately. In addition the basic structure has to be tested as described in paragraph 6.4.8.
6.4.7.3. Traction device adapted for the test of side-facing seats is shown in Annex 5, Figure 1b.
6.4.8. Test of the basic structure of side-facing seats
6.4.8.1. The basic structure of a side-facing seat or a group of side-facing seats shall be tested according to the forces as prescribed in paragraph 6.4.3. for M3 vehicles.
6.4.8.2. The test load shall be directed forward in relation to the vehicle, corresponding to the procedure prescribed in paragraph 6.3. In the case that side-facing seats are grouped together the basic structure shall be tested simultaneously for each seating position in the group.
6.4.8.3. The point of application of the forces prescribed in paragraphs 6.4.3. and 6.4.4. shall be as close as possible to the H-Point and on the line defined by a
