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 means. The close-proximity rear-view field of vision shall be obtained from the minimum number of mirrors and monitors.
         15.2.4. In the case of mirrors consisting of several reflecting surfaces which are either of different curvature or make an angle with each other, at least one of the reflecting surfaces shall provide the field of vision and have the dimensions specified for the class to which they belong.
         15.3. Field of detection
         The field of detection shall be bounded by the following planes (see figure 4):
              (a)                    A transverse vertical plane passing through a point 200 mm from the outermost point of the rear of the vehicle;
              (b)                   A transverse vertical plane passing through a point 1,000 mm behind the outermost point of the rear of the vehicle;
              (c)                    Two longitudinal vertical planes parallel to the longitudinal vertical median plane passing through the outermost point of each side of the vehicle.

Field of detection

         15.3.1. When tested under the conditions defined in Annex 10 the requirement for field of detection shall be considered to be satisfied if the information as defined in paragraph 17.2 is provided to the driver.
         15.4. Devices for reversing motion
         15.4.1. Position
         15.4.1.1. Devices for means of rear visibility or detection shall be so placed that the driver, when sitting on the driving seat in a normal driving position, has a clear view of the road to the rear, side(s) or front of the vehicle.
         15.4.1.2. In the case of any vehicle, which is in chassis/cab form when the field of vision or detection is measured, the minimum and maximum body widths, heights and lengths shall be stated by the manufacturer and, if necessary, simulated by dummy headboards. All vehicles and devices for means of rear visibility or detection configurations taken into consideration during the tests shall be shown on the type-approval certificate for a vehicle with regard to the installation of devices for means of rear visibility or detection (see Annex 4). This includes information related to a range of device installation positions (in length, width and height).
         15.4.1.3. Devices for means of rear visibility or detection shall not project beyond the external bodywork of the vehicle substantially more than is necessary to comply with the requirements concerning fields of vision or fields of detection.
         15.4.1.4. Devices for means of rear visibility or detection shall be fitted in such a way that the devices do not move so as significantly to change the field of
