to tests and shall fulfil the requirements specified below, including the tests for strength prescribed in paragraphs 7.5.1. and 7.5.2. below. (These requirements are such that they exclude non-locking retractors.)
              6.2.5.1. Manually unlocking retractors
              6.2.5.1.1. The strap of a safety-belt assembly equipped with a manually unlocking retractor shall not move more than 25 mm between locking positions of the retractor.
              6.2.5.1.2. The strap of a safety-belt assembly shall extract from a manually unlocking retractor within 6 mm of its maximum length when a tension of not less than 1.4 daN and not more than 2.2 daN is applied to the strap in the normal direction of pull.
              6.2.5.1.3. The strap shall be withdrawn from the retractor and allowed to retract repeatedly by the method described in paragraph 7.6.1. until 5,000 cycles have been completed. The retractor shall then be subjected to the corrosion test given in paragraph 7.2. and to the dust test given in paragraph 7.6.3. below. It shall then satisfactorily complete a further 5,000 cycles of withdrawal and retraction. After the above tests, the retractor shall operate correctly and still meet the requirements of paragraphs 6.2.5.1.1. and 6.2.5.1.2. above.
              6.2.5.2. Automatically locking retractors
              6.2.5.2.1. The strap of a safety-belt assembly equipped with an automatically locking retractor shall not move more than 30 mm between locking positions of the retractor. After a rearward movement of the wearer, the belt shall either remain at its initial position or return to that position automatically on subsequent forward movements of the wearer.
              6.2.5.2.2. If the retractor is part of a lap belt, the retracting force of the strap shall be not less than 0.7 daN when measured in the free length between the dummy and the retractor in accordance with paragraph 7.6.4. below.
               If the retractor is part of an upper torso restraint, the retracting force of the strap shall be not less than 0.1 daN and not more than 0.7 daN when similarly measured.
              6.2.5.2.3. The strap shall be withdrawn from the retractor and allowed to retract repeatedly by the method described in paragraph 7.6.1. until 5,000 cycles have been completed. The retractor shall then be subjected to the corrosion test given in paragraph 7.2. and after that to the dust test given in paragraph 7.6.3. below. It shall then satisfactorily complete a further 5,000 cycles of withdrawal and retraction. After the above tests the retractor shall operate correctly and still meet the requirements of paragraphs 6.2.5.2.1. and 6.2.5.2.2. above.
              6.2.5.3. Emergency locking retractors
              6.2.5.3.1. An emergency locking retractor, when tested in accordance with paragraph 7.6.2. below, shall satisfy the conditions below. In the case of a single sensitivity, according to paragraph 2.14.4.1. of this Regulation, only the specifications regarding deceleration
