Salt spray test of road vehicle lamps

The purpose of the salt spray test is to assess the salt spray corrosion resistance of products or metal materials, and the judgment of the salt spray test results is a judgment on the product quality. Whether its judgment results are correct and reasonable is the key to correctly measuring the salt spray corrosion resistance quality of the product or metal. The salt spray test of road vehicle lamps can determine the salt spray corrosion resistance of exterior lighting and light signaling devices on motor vehicles and trailers.
Zhongke Testing Reliability Experiment Center has the ability to test the environmental durability of various lighting devices, and provides professional salt spray testing services for external lighting and light signaling devices of road vehicles.

Vehicle front lights include: low beam, high beam, front position lights, daytime running lights, front turn lights, front fog lights, corner lights, side turn lights, parking lights;
Vehicle rear lights include: brake lights, rear position lights, rear turn lights, reversing lights, rear fog lights, rear retroreflectors, high-mounted brake lights, license plate lights;
Common lights for large vehicles include: front profile lights, rear profile lights, side marker lights, reflective logos, and tail sign boards.

1. Open all drain holes or other openings on the sample and place the sample in the test box.
2. The sample should undergo 10 cycles of testing, with each cycle spraying for 23 hours and drying for 1 hour. The test should end in the drying phase.
3. After the test, the test surface was cleaned with deionized water for 5 minutes and dried under natural convection conditions.
4. Result judgment: The sample should be free of corrosion, and the light distribution performance should meet the requirements of relevant standards.
