SAE J575 – Test Methods and Equipment for Lighting Devices for Use on Vehicles Less than 2032 mm in Overall Width

Standard: SAE J575: Test Methods and Equipment for Lighting Devices for Use on Vehicles Less than 2032 mm in Overall Width

Scope: SAE J575 outlines standardized test methods for evaluating the durability, performance, and reliability of automotive exterior lighting devices. These procedures are designed to simulate environmental and operational conditions that lighting components may encounter during their service life.

Applicable Products:
This standard applies to:

Automotive OEMs
Tier 1 and Tier 2 suppliers
Lighting component manufacturers

Test Procedure: Intertek offers comprehensive SAE J575 testing services through its global network of accredited laboratories. The test procedures include:

Photometric Testing: Verifies luminous intensity and beam pattern compliance.
Vibration Testing: Assesses structural integrity under mechanical stress.
Moisture and Water Intrusion Testing: Evaluates resistance to rain, splash, and immersion.
Dust Exposure: Determines sealing effectiveness against particulate ingress.
Corrosion Resistance: Simulates exposure to salt spray and other corrosive environments.
Thermal Shock and Temperature Cycling: Tests resilience to rapid temperature changes.
Chemical Resistance: Assesses impact of automotive fluids and cleaning agents.

End Result: Successful completion of SAE J575 ensures that lighting systems meet minimum safety and performance criteria under real-world conditions. It is often used in conjunction with regulatory standards such as FMVSS 108 to validate compliance for road use.
