6. RequIrements
6.1 Performance Requirements—A device when tested in accordance with the test procedures specified in
Section 5 shaH meet the following requirements:
6.1.1 VIBRATION—SAE J575.
6.1.2 MO4STURE—SAE 1575.
6.1.3 D0ST—SAE 1575.
6.1.4 CoRnosIoN—SAE 1575.
6.1.5 PHOTOiIETRV—SAE J575.
16.1.5.1 The lamp shall be designed to conform to the zone total photometric requirements of Table 1 and its
footnotes.The summation of the luminous intensity measurements at the test points In a zone shall be at least the value shown.
6.1.5.2 A multiple compartment lamp or multiple lamps may be used to meet the photometric requirements. If a multiple compartment lamp or multiple lamps are used and the distance between adjacent light sources does not exceed 560 mm for two compartments or lamp arrangements and does not exceed 410 mm for three compartments or lamp arrangements. then the combination of the compartments or lamps must be used to meet the photometric requirements for the corresponding number of lighted sections in Table 1. 11 the distance between adjacent light sources exceeds the previous dimensions, each compartment or lamp shall comply with the photometric performance requirements for one lighted section in Table 1.
6.1.5.3 When a tail lamp is combined with the turn signal or stop lamp, the signal lamp intensity shall not be less than three times the luminous intensity of the tail lamp at any test point, except that at H•V, H•51, H5R, and 5U-V. the turn signal or stop lamp intensity shall not be less than five times the luminous Intensify of the tail lamp. It a multiple compartment or multiple lamp arrangement is used and the distance between optical axes for both the tail lamp and the turn signal or stop lamp is within the dimensions specified in 6.1.5.2, the ratio of the turn signal or stop lamp to the tail lamp shall be computed with all the compartments or lamps lighted. If a multiple compartment or multiple lamp arrangement is used and the distance between optical axes for one of the functions exceeds the dimensions specified in 6.1.5.2. the ratio shall be computed for only those compartments or lamps where the tail lamp and turn signal or stop lamp are Optically combined. When the tail lamp is combined with the turn signal or stop lamp and the maximum luminous intensity of the tail lamp is located below honzontal and within an area generated by a 1.0 degree radius around a test point, the ratio for the test point may be corruted using the lowest value of the tall lamp luminous intensity within the generated area,
6.1.6 WARPAGE—SAE J575.
6.1.7 COLOn—The color of the light from a tail lamp shall be red as specified in SAE 1578.
7.1.2 The luminous intensity of incandescent filament bulbs will vary with applied voltage. The electrical wiring In the vehicle should be adequate to supply design voltage to the lamp filament.
7.1.3 Performance of lamps may deteriorate significantty as a result of diii, grime, and/or snow accumulation on their optical surfaces. Installation of lamps on vehides should be considered to minimize the effect of these factors.
7.1.4 Where lt is expected that lamps must perform in extremely severe envrorlrnents, such as in off-highway, mining, fuel haulage, or where it is expected that they will be totally immersed in water, the user should specify lamps specifically designed for such use.
