SAE J575 Test Methods and Equipment for Lighting Devices Used in Vehicles With Total Width Less Than 2032 mm

Developed by the Society of Automotive Engineers (SAE), the SAE J575 standard is designed as a guide to standard practice and is subject to occasional updates to keep up with experience and technical developments. This standard contains requirements for standardized laboratory tests, test methods and equipment, and lighting devices within the scope of practices and standards recommended by the Society of Automotive Engineers (SAE). This standard is designed for devices used in vehicles with a width of less than 2032 mm. Tests for vehicles with an overall width greater than 2032 mm are covered by the SAE J2139 standard. Device-specific tests and requirements are contained in current Society of Automotive Engineers (SAE) technical reports.

The test methods defined in the framework of this standard are:

• Vibration test. This test evaluates the sampler's ability to resist damage caused by stresses from vibration.
• humidity test. This test evaluates the ability of the sampler to resist moisture leakage from a spray of water and determines the drainage capacity of devices with drain holes or other exposed openings in the device.
• Dust test. This test evaluates the sampler's ability to resist dust infiltration, which significantly affects its photometric output.
• Corrosion test. This test evaluates the sampler's ability to resist salt corrosion that can degrade the functional properties of the instrument.
• Photometry test. This test measures light intensities at test points throughout the light distribution pattern as specified in the Society of Automotive Engineers (SAE) technical report applicable to the sample device.
• Warping test on devices with plastic components. This test evaluates the ability of the plastic components of the sampler to resist damage from ambient and light source heat.

These test methods are individual test methods that do not need to be performed in a particular order. These test methods are performed simultaneously on separately mounted samples, accelerating the completion of the tests.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides testing services for lighting devices used in vehicles with a total width of less than 575 mm, within the scope of SAE J2032 standard, with its trained and expert staff and advanced technological equipment. .
