Close-proximity rear-view field of vision

         15.2.1. Requirements
         When tested under the conditions defined in Annex 9 the requirement for close-proximity rear-view field of vision shall be considered to be satisfied if the defined field of vision can be seen:
              (a)                    For the test objects in the first row (Test objects A, B, and C):
              A 0.15 m x 0.15 m area or the top of the test object shall be visible at least one position on each test object.
              (b)                   For the test objects in the second row (Test objects D, E, and F) and the third row (Test objects G, H, and I);
              The whole test object shall be seen.
         15.2.1.1. Via the direct view from the driver's looking back ocular points; or
         15.2.1.2. Via the direct view from the driver's looking back ocular points combined with a close-proximity rear-view mirror installed at the rear end of the vehicle supporting this direct view; or
         15.2.1.3. Via a device of indirect vision (mirror or CMS or other) approved to UN Regulation No. 46; or
         15.2.1.4. Via a means of rear visibility (mirror or RVCS or other) complying with this Regulation; or
         15.2.1.5. Via a device of detection system that complies with this Regulation except for the field of detection (e.g. very short range); or
         15.2.1.6. Via a combination of devices of paragraphs 15.2.1.3, 15.2.1.4. and 15.2.1.5. except a combination of RVCS and mirror(s) or close-proximity rear-view mirror.
         15.2.1.7. The options 15.2.1.1 and 15.2.1.2 only apply to the vehicle categories M1 and N1, when the distance between looking back ocular point to vehicle rear-end does not exceed 2000 mm and when the vehicle has one seating row.
         15.2.2. The close-proximity rear-view field of vision shall be established using ambinocular vision, the eyes being at the "driver's ocular points" as defined in paragraph 12.1. above. The fields of vision shall be determined when the vehicle is in running order as defined in the consolidated Resolution on the Construction of vehicles (R.E.3) (ECE/TRANS/WP.29/78/Rev.6, para. 2.2.5.4.), plus for M1 and N1 vehicles one front seat passenger (75 kg). When established through windows, the glazing shall have a total light transmission factor in accordance with UN Regulation No. 43, Annex 24.
         In case of direct view from the driver's looking back ocular points the vertical position of rear seat headrests shall be set at the designed position of assumed to use or the highest position if the headrest has multiple position settings or at the position agreed with the Technical Service.
         15.2.3. In the case of a combination of means of rear visibility or detection, each entire transverse row of test objects shall be seen by one of these
