This SAE Recommended Practice is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances. This document provides standardized laboratory tests, test methods and equipment, and requirements for lighting devices covered by SAE Recommended Practices and Standards. It is intended for devices used on vehicles less than 2032 mm in width. Tests for vehicles larger than 2032 mm in overall width are covered in SAE J2139. Device specific tests and requirements can be found in applicable SAE technical reports.
Rationale
1. To provide better flow, the document was re-numbered to separate the tests into the following groups. Group A – Photometry, Group B – Mechanical, Group C – Thermal, Group D – Water, Group E – Other.
2. The scope was changed to clarify purpose and to reflect that the test procedures described in this document are generic and not lamp specific. All references to specific lamps to be tested has been removed (i.e. tests for headlamps and fog lamps is now a test for a lamp)
3. The reference document for salt fog testing was updated to the 2003 version reflecting the change in the salt purity requirement.
4. A review of this document revealed no mention of how DRL function should be tested. Changes to photometry voltage and lamp testing operation reflect specific test requirements of DRL functions
5. Numbering in Vibration test was corrected, as well as the test procedure added for the J577 vibration machine, removing the reference to J2139 for the procedure.
6. Updated thermal cycle figure to provide better resolution for dwell times. Changed text to reflect the actual minimum and maximum test durations based on the temperature transition rates.
7. Due to comments in the last ballot, wording to better clarify solar irradiation direction was added. In recent years many tests have been added to this document and the numbering was mostly chronological.
8. References to historical origins of a test and references to non-existent tables removed from the document.

We wanted to make subscribers to the Technical Papers 1998-Present collection aware of an improvement that has been made (if you do not subscribe to this collection, you can disregard this notice). Effective January 2020, SAE has restructured the existing collections to provide a better user experience. Named collections within SAE MOBILUS will be better aligned to reflect the content contained within. The collections will now be broken out as follows:
- Journal Articles 2008-2017: includes all journal content published within the specified date range
- Conference Journal Articles 2018-Present: includes all event/conference papers that have been selected for journal publication and SAE International Journal of Advances and Current Practices in Mobility, which publishes the top papers from SAE events
Please note that there is nothing you need to do at this time and access to your content will not be affected.
Search Tips
Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
