Test Methods and Equipment for Lighting Devices and Components for Use on Vehicles Less than 2032 mm in Overall Width J575_200611

Revision for photometric measurement and scan

It has been the intent that signal lamp luminous intensity measurements in the required angular domain maintains a good continuity with no visible dark streaks or points. This will ensure the signal lamps' visibility for drivers and pedestrians. The intent of the current requirement has not been clearly stated in this document. The revision is to clarity the measurement and scan requirement to ensure adequate beam pattern continuity for a lamp.

Revision for addition of forward lighting environmental tests to this document

During the SAE Lighting Committee meetings held in Santa Fe, NM in spring 2006, an agreement was reached that all tests, including tests only required for forward lighting devices, should be specified and required in this document as much as possible. In this revision, these tests include Impact Test, Chemical Resistance Test, Abrasion Test, Thermal Cycle Test, Internal Heat Test, and Corrosion Resistance Test that are specified and required in SAE J1383. The information transferred from SAE J1383 is not changed except for editorial format for this document. This is to make this document more centralized with all lighting related tests and will be more user friendly for individuals using this document for lamp design and testing.
