DEFINITIONS 3.1 Reflex Reflectors Devices that are used on vehicles to give an indication of presence to an approaching driver by reflected light from the headlamps on the approaching vehicle.

14、3.2 The Observation Angle The angle between a line from the observation point to the center of the reflector and a second line from the center of the reflector to the source of illumination. 3.3 The Entrance Angle The angle between the axis of the reflex reflector and a line from the center of the r

15、eflector to the source of illumination. 4. IDENTIFICATION CODE Reflex reflectors may be identified by the Code “A“ in accordance with SAE J759. SAE J594 Revised FEB2010 Page 3 of 65. TESTS 5.1 SAE J575 is a part of this report. The following tests are applicable with the modifications as indicated.

16、5.1.1 Vibration Test 5.1.2 Moisture 5.1.3 Dust Test 5.1.4 Corrosion Test 5.1.5 Photometry In addition to the test procedures in SAE J575, the following apply: 5.1.5.1 Test Setup Photometric measurement shall be made at a test distance of at least 30 m with the reflex reflector setup for testing as s

17、hown in Figure 1. The reflex reflector shall be mounted in a goniometer with the center of the reflex area at the center of rotation and at the same horizontal level as the source of illumination. FIGURE 1 - SETUP FOR TESTING 5.1.5.2 Light Source and Sensor The source of illumination shall be a proj

18、ector with a 50 mm 5 mm effective diameter and a lamp filament operating at 2856 K (nominal) color temperature. In making photoelectric measurements, the opening to the photo cell shall not be more than 13 mm vertical by 25 mm horizontal with the observation point above (geometrically) the source of

19、 illumination. 5.1.5.3 Measurements Reflex reflectors shall be photometered at the observation and entrance angles shown in Figure 2. The entrance angle shall be designated left, right, up, and down in accordance with the position of the source of illumination with respect to the axis of the reflex

20、reflector as viewed from behind the reflector. The H-V axis of reflex reflectors shall be taken parallelto the longitudinal axis of the vehicle for rear reflectors and perpendicular to a vertical plane parallel to the longitudinal axis of the vehicle for side reflectors. SAE J594 Revised FEB2010 Pag

21、e 4 of 6Photometric measurements shall be made photoelectrically. The recorded value for each test point shall be the quotient of luminous intensity of the reflected light expressed as millicandela (candela) divided by the illumination on the reflector measured in lux (foot candle). Also, the illumi

22、nation on the reflex reflector from the source of illumination shall be measured in lux (foot candle). Reflex reflectors may have any linear or area dimension; but, for the photometric test, a maximum projected area of 7740 mm2contained within a 254 mm diameter circle shall be exposed. 5.1.5.4 Rotat

23、ional Position Reflex reflectors that do not have a fixed rotational position with respect to the vehicle shall be rotated 360 degrees about their axis to find the minimum millicandela per incident lux (candela per incident foot candle), which shall be reported for each test point. If the output fal

24、ls below the minimum requirement at any test point, the reflector shall be rotated 5 degrees about its axis from the angle where the minimum output occurred; and the maximum millicandela per lux (candela per foot candle) within the angular range reported as a tolerance value. Reflex reflectors that,

25、 by their design or construction, permit mounting on the vehicle in fixed rotational position shall be tested in this position. A visual locator, such as the word TOP, shall not be considered adequate to establish a fixed rotational position on the vehicle. 5.1.5.5 Uncolored Reflections If uncolored

26、 reflections from the front surface interfere with photometric readings at any test point, the operator shall check 1 degree above, below, right, and left of the test point, and report the lowest reading and location. The latter must meet the minimum requirement for the test point. 5.2 Color Test SA

27、E J578 is a part of this report. Additionally, the test sample may be either the reflex reflector or a disc of the same material, technique of fabrication, and dye formulation as the reflex reflector. If a disc is used for color determination by the transmission technique, the thickness should be tw

28、ice the thickness of the reflector as measured from the face of the lens to the apexes of the reflecting elements. For either sample, a Source “A“ illumination shall be used for color measurement.6. REQUIREMENTS 6.1 Performance Requirements A reflex reflector, when tested in accordance with the test

29、 procedures specified in Section 5, shall meet the following requirements:6.1.1 Vibration SAE J575. 6.1.2 Moisture SAE J575, except that in the case of sealed units the alternate water submersion test (5.2.4) is required. 6.1.3 Dust SAE J575. 6.1.4 Corrosion SAE J575. SAE J594 Revised FEB2010 Page 5

30、 of 66.1.5 Photometry SAE J575. The reflex reflectors under test shall meet the photometric performance requirements contained in Figure 2 or Figure 2A.

32、reflex reflector shall be red, yellow, or white as defined in SAE J578. 6.2 Material Requirements Plastic materials used in the optical portion of each reflex reflector unit shall meet the requirements of SAE J576. 6.3 Photometric Design Requirements 6.3.1 If a reflex reflector is optically combined

33、 with signaling or marking bulb type devices, it shall be photometered independently by masking from the other functions and shall meet the performance values contained in Figure 2 or 2A. 6.4 Installation Requirements Reflex reflectors shall be designed to comply with all photometric requirements of

34、 Figure 2 as installed on the vehicle, with all vehicular obstructions considered. 7. GUIDELINES 7.1 Photometric Design Guidelines Reflex reflectors, when tested in accordance with 5.1.5, should be designed at least equal to the values contained in Figure 2 or 2A. 7.2 Installation Guidelines The fol

35、lowing guidelines apply to reflex reflectors as used on the vehicle and shall not be considered a part of this report: 7.2.1 Reflex reflectors when used on the exterior of vehicles should be mounted to minimize the accumulation of dirt, grime, and/or snow so that adequate illumination is maintained

36、from the low beam headlamps of approaching vehicles.7.2.2 If reflex reflectors must perform in severe environments, such as periodic total immersion in water, the user should specify reflex reflector designs suitable for such use. 8.
