- Commodity name: Solar Simulation Test
Solar simulation testing, also known as solar radiation testing, uses a xenon lamp light source to simulate the full solar spectrum (ultraviolet UV + visible light + infrared thermal radiation). Within the test chamber, it replicates outdoor exposure and high-temperature sunlight conditions found in automotive engine compartments or dashboards, while simultaneously controlling temperature and humidity. This assessment evaluates the product’s weathering reliability under combined light and high-temperature stress and is commonly employed for reliability verification of outdoor and in-vehicle electronic products, as well as for reproducing RMA‑related failures caused by prolonged sun exposure.
Test Method
1. Place the specimen under standard atmospheric conditions (23°C ± 2°C, 50% ± 5% RH) for at least 2 hours, and record its initial state (appearance and performance parameters).
2. Start the equipment according to the set parameters (radiant intensity, temperature, and cycling mode), and expose the test specimen to the irradiation environment. (If a cycling mode is used, during the dark phase, control both temperature and humidity—for example, reduce the temperature to 30°C and increase the relative humidity to 95% to simulate nighttime condensation.)
3. After the test is completed, allow the specimen to equilibrate under standard atmospheric conditions for 2 hours.
During the test, equipment parameters were checked regularly to ensure stability.
