Test Methods and Equipment for Lighting Devices for Use on Vehicles Less than 2032 mm in Overall Width
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.
Underhood Thermal Test added for lamp assemblies with housings exposed to engine compartments. The Underhood Thermal Test is used to ensure lamp assemblies are capable of operating without degradation in conditions of elevated temperatures generated by operation combined with heat input from the surrounding vehicle environment, including engine compartment components. See new sections 4.9 and 5.9. A new figure 5 was added in section 4.9 resulting in re-numbering of two figures and subsequent references in the text. Table of contents updated to reflect additions and omitted 4.1 heading added.
