SAE J583_201510

This SAE standard provides test procedures, performance requirements, design guidelines and installation guidelines for front fog lamps. Revised Figure 2 - Photometric requirements for harmonized front fog lamp luminous intensity (cd) to correct errors and harmonize with current ECE R19 requirements. 1 Revised left side of drawn Line 1, 2, 3, 4, 5, 6, and 7 in the figure to end at correct angular value. Current lines extend to the left beyond specified angular extent of each line. 2 Reordered footnotes to list in a more logical order. 3 Separated current footnote #3 into footnote #4 for Line 6 and #5 for Line 7 to help with clarity. 4 Corrected footnote #4 that line 6 is a maximum and minimum measured line. 5 Corrected footnote #5 to state Line 7 is required to be less than 50% of Line 6 maximum. Current footnote incorrectly states Line 7 is required to be less than 50% of Line 6 minimum. 6 Revised drawn Line 6 and 7 along with modifying the text box pointing to each to indicate there is an asymmetric option to reduce the inboard angular extent if the lamps are a pair of lamps with an asymmetric beam pattern. This harmonizes with the current ECE R19. 7 Added footnote #7 allowing inboard angular relief for lines 6 and 7 consistent with figure modification above.
