7.4.1.1. the breaking load of the strap, determined as prescribed in paragraph 7.4.2. below, shall be not less than 1,470 daN.  The difference between the breaking loads of the two samples shall not exceed 10 per cent of the greater of the breaking loads measured.

           6.3.3. Strength after special conditioning

           In the case of the two strap samples conditioned in conformity with one of the provisions of paragraph 7.4.1. (except 7.4.1.1.) below, the breaking load of the strap shall be not less than 75 per cent of average of the loads determined in the test referred to in paragraph 6.3.2. and not less than 1,470 daN.  The technical service conducting the tests may dispense with one or more of these tests if the composition of the material used or information already available renders the test or tests superfluous.

6.4. Belt assembly or restraint system

6.4.1. Dynamic test

           6.4.1.1. The belt assembly or restraint system shall be subjected to a dynamic test in conformity with paragraph 7.7. below.

           6.4.1.2. The dynamic test shall be performed on two belt assemblies which have not previously been under load, except in the case of belt assemblies forming part of restraint systems when the dynamic test shall be performed on the restraint systems intended for one group of seats which have not previously been under load.  The buckles of the belt assemblies to be tested shall have met the requirements of paragraph 6.2.2.4. above.  In the case of safety‑belts with retractors, the retractor shall have been subjected to the dust resistance test laid down in paragraph 7.6.3.; in addition, in the case of safety‑belts or restraint systems equipped with a pre‑loading device comprising pyrotechnic means, the device shall have been subjected to the conditioning specified in paragraph 7.9.2.

           6.4.1.2.1. The belts shall have undergone the corrosion test described in paragraph 7.2., after which the buckles shall be subjected to 500 additional opening and closing cycles under normal conditions of use.

           6.4.1.2.2. Safety‑belts with retractors shall have been subjected either to the tests described in paragraph 6.2.5.2. or to those described in paragraph 6.2.5.3.  If, however, a retractor has already been subjected to the corrosion test in accordance with the provisions of paragraph 6.4.1.2.1., above, this test need not be repeated.

           6.4.1.2.3. In the case of a belt intended for use with a belt adjustment device for height, as defined in paragraph 2.9.6. above, the test shall be carried out with the device adjusted in the most unfavourable position(s) chosen by the technical service responsible for testing.  However, if the belt adjustment device for height is constituted by the belt anchorage, as approved in accordance with the provisions of Regulation No. 14, the technical service responsible
