10、of Materials 3. DEFINITIONS 3.1 A LICENSE PLATE ILLUMINATION DEVICE A device that illuminates the license plate on the rear of a vehicle. 4. LIGHTING IDENTIFICATION CODE License plate illumination devices may be identified by the code “L“ in accordance with SAE J759. 5. TESTS 5.1 SAE J575 is a part
11、of this document. The following tests are applicable with modifications as indicated. 5.1.1 Vibration Test 5.1.2 Moisture Test 5.1.3 Dust Test 5.1.4 Corrosion Test 5.1.5 Warpage Test on Devices With Plastic Components 5.2 Color Test SAE J578 is part of this document. 5.3 Photometry Test 5.3.1 Test E
12、quipment 5.3.1.1 Test Plate All luminance measurements shall be made on a rectangular test plate of clean, smooth, matte white blotting paper or an equivalent material with a diffuse white surface. The test plate shall have a total reflectance factor of 85% 5% when measured in accordance with ASTM E
13、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 be located on the face of the test plate as shown in Figure 1. For devices used on motorcycles, the test stations sha
14、ll be located on the face of the test plate as shown in Figure 2. SAE INTERNATIONAL J587 NOV2017 Page 3 of 5 Figure 1 - Test plate for vehicles other than motorcycles Figure 2 - Test plate for motorcycles 5.3.1.2 Luminance Meter A luminance meter shall be used to measure the luminance over the entir
15、e area of each circular test station on the test plate. The meter shall be calibrated to measure luminance in cd/m2. Measurements shall not include any area beyond that of the test station. SAE INTERNATIONAL J587 NOV2017 Page 4 of 5 5.3.2 Test Procedure 5.3.2.1 The test plate shall be mounted in the
16、 position ordinarily taken by the license plate. The face of the test plate that is measured by the luminance meter, shall be pointed toward the luminance meter and located 2 mm from the plane of the license plate holder. 5.3.2.2 Luminance measurements shall be made with the optical axis of the lumi
17、nance meter perpendicular to the test plate surface within 5. 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 over all specified test points. For
18、 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 the average of the two lowest lumin
19、ance values recorded at the six test stations shall be taken as maximum and minimum, respectively. 5.4 Plastic Materials SAE J576 is a part of this report. 6. REQUIREMENTS 6.1 Performance Requirements A device, when tested in accordance with the test procedures specified in Section 5, shall meet the
20、 following requirements: 6.1.1 Vibration - SAE J575 6.1.2 Moisture - SAE J575 6.1.3 Dust - SAE J575 6.1.4 Corrosion - SAE J575 6.1.5 Warpage - SAE J575 6.2 Color The color of the light from the license plate illumination device(s) shall be white as specified in SAE J578. 6.3 Photometry The lamp shal
21、l be designed to conform to the following 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
22、 ratio of maximum to minimum luminance shall not exceed 25/1. 6.3.3 If a tail or stop lamp is combined with a license plate illumination device, the combination shall also meet the requirements for these devices. 6.4 Plastic Materials Plastic materials used in the optical parts shall meet the requir
23、ements of SAE J576. Since some license plate illumination devices are mounted in shaded or protected locations, attention is called to the section of SAE J576 which covers exposure time and conditions. SAE INTERNATIONAL J587 NOV2017 Page 5 of 5 6.5 Design Requirements 6.5.1 License plate illuminatio
24、n 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 periphery. License plate illumination devices for motorcycles shall be of such size and design as to pr
25、ovide 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 than 1.2 m from the ground, the angle between the plane of the license plate and a vertical plane perp
26、endicular to the plane of the ground on which the vehicle stands shall be 15. If the upper edge of the license plate is not more than 1.2 m from the ground, the plate surface bearing the license numbers shall face between 30 upward and 15 downward from the vertical plane. 6.6 Installation Requiremen
27、ts 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 feature unless the device(s) is designed to comply with the obstructions considered. 6.6.2 Except for a 13 mm wide border around
28、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 the vehicle. 6.6.3 The license plate illumination device(s) shall be installed so that no white light is projected from the illum
29、ination 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 illuminate the plate from the top or sides. Illumination from the bottom of the plate is permitted provided other illumination is also p
30、rovided 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 considered part of the requirements. 7.1 The license plate holding device shall be designed and constructed to provide a substantia
31、l plane surface on which to mount the plate. 8.
