5.4.3.7.3.2.      In the case of two anchorages, within whichever of the above defined dihedrals is suitable, provided that each anchorage is not more than 50 mm distant from the
symmetrically-located, mirror-image position of the other anchorage about plane P, as defined in paragraph 5.1.6. of the seat in question.

5.5.                               Dimensions of threaded anchorage holes

5.5.1.                         An anchorage shall have a threaded hole of 7/16 inch (20 UNF 2B).

5.5.2.                         If the vehicle is fitted by the manufacturer with safety-belts which are attached to all anchorages prescribed for the seat in question, these anchorages need not meet the requirement set out in paragraph 5.5.1., provided that they comply with the other provisions of this Regulation. In addition, the requirement set out in paragraph 5.5.1. shall not apply to additional anchorages which meet the requirement set out in paragraph 5.4.3.7.3.

6.1.                               General for seat belt anchorages tests

6.1.1.                         Subject to application of the provisions of paragraph 6.2., and at the request of the manufacturer;

6.1.1.1.                   the tests may be carried out either on a vehicle structure or on a completely finished vehicle;

6.1.1.2.                   The tests may be restricted to the anchorages relating to only one seat or one group of seats on the condition that:

            (i)        the anchorages concerned have the same structural characteristics as the anchorages relating to the other seats or group of seats; and

            (ii)      where such anchorages are fitted totally or partially on the seat or group of seats, the structural characteristics of the seat or group of seats are the same as those for the other seats or groups of seats.

         6.1.1.3.                   windows and doors may be fitted or not and closed or not;

The seats shall be fitted and placed in the position for driving or use chosen by the technical service responsible for conducting approval tests to give the most adverse conditions with respect to the strength of the system. The position of the seats shall be stated in the report. The seat-back shall, if its inclination is adjustable, be locked as specified by the manufacturer or, in the absence of any such specification, in a

position corresponding to an effective seat-back angle as close as possible to 25° for vehicles of categories M1 and N1 and to 15° for vehicles of all other categories.

6.2.                               Securing the vehicle for seat belt anchorages tests and for ISOFIX anchorages tests.
