Salt Spray Test for LED Lamps

With the development of the times and the improvement of people’s environmental awareness, LED lamps have become a popular choice for various applications. For buyers, the reliability and durability of lamps are crucial, especially for those lamps used in harsh environments such as coastal and industrial areas, because those lamps are easily degraded due to corrosion. Therefore, LED lamp manufacturers will conduct strict salt spray tests on lamps to ensure the quality and life of lamps.

The salt spray test of LED lamps refers to exposing LED lamps to salt spray environments to simulate the use of marine climate or high salinity environments to test the corrosion resistance of LED lamps. Salt spray testing can evaluate the corrosion resistance of LED lamps in harsh environments and verify whether they can work stably for a long time. Through salt spray testing, the external materials, sealing performance, surface coating and other properties of LED lamps can be detected to ensure that LED lamps can still work reliably in harsh environments. Salt spray testing of LED lamps is one of the essential quality tests in the LED lamp industry and an important means to ensure the quality and stable performance of LED lamps.

Relevant standards and protocols manage the salt spray testing process to ensure consistency and reliability. Some commonly used standards include:

ASTM B117: Standard Specification for Operating Salt Spray (Fog) Apparatus

ISO 9227: Corrosion Tests in Artificial Atmospheres – Salt Spray Tests

ISO 16701: Corrosion of Metals and Alloys – Corrosion in Artificial Atmospheres – Accelerated Corrosion Tests Including Exposure to and Intermittent Spraying of Salt Solutions Under Controlled Humidity Conditions

These standards provide detailed guidelines for conducting salt spray tests, including sample preparation, test conditions, evaluation criteria, and reporting requirements.

After the test is completed, the results are documented in a detailed report. The report typically includes information about the test procedure, test conditions, evaluation criteria, and overall observations and findings. Photographic evidence and data sheets may also be included to support conclusions drawn from the test results. Purchasers can choose the most appropriate lamp based on the salt spray test report provided by the lamp manufacturer.
