11、ite surface. The test plate shall have a total reflectance factor of 85% 5% when measured in accordance with ASTM E 179 (0/t illumination/viewing geometry). The size of the test plate is shown in Figure 1 or 2, as applicable. For devices used on vehicles other than motorcycles, test stations shall b

15、EP2003 - 4 - 5.3.2 TEST PROCEDURE 5.3.2.1 The test plate shall be mounted in the position ordinarily taken by the license plate. The face of the test plate shall be located 2 mm from the plane of the license plate holder toward the luminance meter. 5.3.2.2 Luminance measurements shall be made with t
16、he optical axis of the luminance meter perpendicular to the test plate surface within 5 degrees. Measurements shall be recorded at each of the circular test station areas specified in Figure 1 or Figure 2, as applicable. 5.3.2.3 Calculate and record the ratio of the maximum to the minimum luminance
17、over all specified test points. For test plates conforming to Figure 1, the average of the two highest and the two lowest luminance values recorded at the eight test stations shall be taken as maximum and minimum, respectively. For test plates conforming to Figure 2, the highest luminance value and
18、the average of the two lowest luminance values recorded at the six test stations shall be taken as maximum and minimum, respectively. 6. Requirements 6.1 Performance Requirements A device, when tested in accordance with the test procedures specified in Section 5, shall meet the following requirement

20、wing requirements: 6.3.1 The luminance at each of the test station areas on the applicable test plate shall be at least 2.0 cd/m2. 6.3.2 For tests based on Figure 1, the ratio of maximum to minimum luminance shall not exceed 30/1. For tests based on Figure 2, the ratio of maximum to minimum luminanc
21、e shall not exceed 25/1.

22、n shall also meet the requirements for these devices. 6.4 Materials Requirements Plastic materials used in the optical parts shall meet the requirements of SAE J576. Since some license plate illumination devices are mounted in shaded or protected locations, attention is called to the section of SAE
23、J576 which covers exposure time and conditions. 6.5 Design Requirements 6.5.1 License plate illumination devices for vehicles other than motorcycles shall be of such size and design as to provide illumination on all parts of a 150 x 300 mm test plate, except for a 13 mm wide border around the plate
24、periphery. License plate illumination devices for motorcycles shall be of such size and design as to provide illumination on all parts of a 100 x 175 mm test plate. 6.5.2 The design shall be such that, when the plate is mounted on a vehicle as intended and the upper edge of the license plate is more
25、 than 1.2 m from the ground, the angle between the plane of the license plate and a vertical plane perpendicular to the plane of the ground on which the vehicle stands shall be 15 degrees. If the upper edge of the license plate is not more than 1.2 m from the ground, the plate surface bearing the li
26、cense numbers shall face between 30 degrees upward and 15 degrees downward from the vertical plane. 6.6 Installation Requirements 6.6.1 The license plate illumination device(s) for vehicles other than motorcycles shall be mounted so as to illuminate the plate without obstruction from any designed fe
27、ature unless the device(s) is designed to comply with the obstructions considered. 6.6.2 Except for a 13 mm wide border around its periphery, visibility of the license plate shall not be obstructed by any part of the vehicle when any point on the license plate is projected directly to the rear of th
28、e vehicle. 6.6.3 The license plate illumination device(s) shall be installed so that no white light is projected from the illumination device(s) directly to the rear of the vehicle. 6.6.4 The license plate illumination device(s) for vehicles other than motorcycles shall be mounted so as to illuminat
29、e the plate from the top or sides. Illumination from the bottom of the plate is permitted provided other illumination is also provided from the top or sides of the plate. 7. Installation Guidelines The following apply to license plate illumination devices as used on the vehicle and shall not be cons
30、idered part of the requirements. 7.1 The license plate holding device shall be designed and constructed to provide a substantial plane surface on which to mount the plate.
