Tests for Signal and Marking Devices Used on Vehicles 2032 mm or More in Overall Width
This SAE Recommended Practice provides standardized laboratory tests, test methods, and performance requirements applicable to signal and marking devices used on vehicles 2032 mm or more in overall width.
Changed 126.96.36.199.7 - Photometric measurements and scan shall be performed with the light source(s) steady burning. The luminous intensity measurements (in candela) shall be recorded for each of the test points and zones specified for the function of the device under test. This is consistent with SAE J575
Changed 188.8.131.52 to reference SAE J1455 instead of SAE J1889. Tests are very similar and was already referencing J1455 for the temperatures.
Added 184.108.40.206 - For any signal and marking device, unless otherwise specified in the applicable SAE document, the minimum luminous intensity (candela) requirement between any two adjacent test points shall be no less than 60% of the lower specified minimum value of the two test points on a horizontal or vertical or diagonal line. The specified minimum value is defined by the individual test point value not the zonal value. This is consistent with SAE J575
