A UV aging test chamber simulates sunlight, moisture, and temperature to evaluate the degree of damage products may suffer under such conditions, such as fading, cracking, or chalking. The primary function of the instrument depends on two key factors.
Generally, UV aging chambers commonly use two types of lamps: UVA and UVB.
-
UVA Lamps:
- Have a longer wavelength and stronger penetration, making them suitable for testing material degradation caused by long-term UV exposure.
- Also known as "long-wave blacklight effect ultraviolet lamps."
-
UVB Lamps:
- More widely used in the market compared to UVA lamps.
- Cause faster material degradation due to their shorter, more intense wavelength.
Safety Precautions When Using UV Lamps
- Avoid direct skin exposure – UV radiation can cause skin damage.
- Do not touch lit or recently turned-off lamps – The surface temperature is extremely high and may cause burns.
- Allow a 10-minute cooldown before restarting or opening the lamp cover – Immediate restarting may damage the lamp or cause burns.
Choosing the Right UV Lamp
Based on years of production experience, Shanghai Linpin advises customers that different UV lamps produce different test results. Therefore, when purchasing a UV aging test chamber, it’s essential to select the appropriate lamp type based on specific testing requirements. Currently, UVA and UVB lamps are the most common options in the market.
