6. Requirements
6.1 Performance Requirements—A device when tested in accordance with the test procedures specified in Section 5, shall meet the following requirements:
6.1 .1 V IBRATION —SAE J575
6.1 .2 M OISTURE —SAE J575
6.1 .3 D UST —SAE J575
6.1 .4 C ORROSION —SAE J575
6.1 .5 P HOTOMETRY —SAE J575
6.1.5.1 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 of a stop lamp. If a multiple compartment 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 41 0 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 (Table 1 ). If the distance between adjacent light sources exceeds the dimensions, each compartment or lamp shall comply with the photometric requirements for one lighted section (Table 1 ).
6.1.5.3 When a tail lamp is combined with the stop lamp, the stop lamp shall not be less than three times the luminous intensity of the tail lamp at any test point; except that at H-V, H-5L, H-5R, and 5U-V, the stop lamp shall not be less than five times the luminous intensity of the tail lamp. If a multiple compartment or multiple lamp arrangement is used and the distance between optical axis for both the tail lamp and stop lamp is within the dimensions specified in 6.1 .5.2, the ratio of the 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 stop lamp are optically combined. When the tail lamp is combined with the stop lamp, and the maximum luminous intensity of the tail lamp is located below horizontal and within an area generated by a 0.5 degree radius around a test point, the ratio for the test point may be computed using the lowest value of the tail lamp luminous intensity within the generated area.
