Select the Appropriate UV Lamp Type:
UVA-340 Lamp: Its spectrum closely simulates the short-wave ultraviolet portion of sunlight (wavelength range 295–360 nm), suitable for realistic outdoor aging simulation.
UVB-313 Lamp: Emits stronger short-wave UV radiation to accelerate material aging, commonly used for rapid screening or high weathering-resistance testing, but may cause non-natural damage if not carefully controlled.
Set Key Test Parameters (Typical Reference Ranges):
Irradiance Control: UVA lamps typically 0.35–1.55 W/m² @ 340 nm; UVB lamps ≤ 1.23 W/m² @ 313 nm.
Black Panel Temperature: Adjustable between 35–80°C, with common experimental settings at 50–65°C.
Humidity Conditions: Relative humidity during condensation can reach 100%; standard requirement not less than 95% RH.
Sample-to-Lamp Distance: Maintain 50 ± 3 mm to ensure uniform irradiation.
Sample Installation and Placement:
Standard sample sizes are typically 75 mm × 150 mm or 75 mm × 300 mm; capacity depends on the model, generally accommodating 24–48 samples simultaneously.
Ensure that sample surfaces are parallel to the UV lamps to guarantee uniform exposure.
Operation Procedure
Power-On and Preheating:
Connect to a suitable power supply (typically AC 220V ±10%, 50 Hz).
Check and set the water level in the test chamber tank, using deionized or distilled water with a resistivity ≥ 500 Ω·m.
Program Test Cycles:
Set cycles for light exposure, condensation, and spraying according to the test requirements. A common cycle is 4 hours of light (temperature 60°C, irradiance 0.76 W/m²) followed by 4 hours of condensation (temperature 50°C, RH 100%).
Spraying mode is primarily used to simulate thermal shock effects caused by rainfall and may be enabled based on actual test needs.
Total test duration can be set between 1–9999 hours.
Start the Device and Run the Test:
