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 7.9.1. below.
              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. above. 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 2.14.6. 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:
              6.4.1.2.3.1. 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 for testing may, at its discretion, apply the provisions of paragraph 7.7.1. below;
              6.4.1.2.3.2. If a flexible shoulder adjustment device for height is part of the belt, it shall be tested as a restraint system and the Technical Service responsible for testing shall apply the provisions under paragraph 7.7.1. that count for testing on the part of the vehicle structure to which the restraint system is normally fitted.
              6.4.1.2.4. In the case of safety-belt with a preloading device the minimum displacement specified in paragraph 6.4.1.3.2. below may be reduced by half. For the purpose of this test, the preloading device shall be in operation.
              6.4.1.2.5. In the case of a safety-belt with tension-reducing device, it shall be subjected to a durability test with such a device in operation mode according to paragraph 6.2.5.3.5 before a dynamic test. The dynamic test shall then be conducted with the tension-reducing device in operation mode.
              6.4.1.3. During this test, the following requirements shall be met:
              6.4.1.3.1. No part of the belt assembly or a restraint system affecting the restraint of the occupant shall break and no buckles or locking system or displacement system shall release or unlock; and
              6.4.1.3.2. The forward displacement of the manikin shall be between 80 and 200 mm at pelvic
