FAQ

1. How does the UV-master simulate outdoor aging?

The UV-master reproduces natural environmental factors including ultraviolet light, temperature, humidity, and rainfall. Samples are exposed to high-intensity UVA/UVB lamps combined with programmable environmental cycles. This accelerated aging process reproduces months or years of outdoor exposure in days or weeks, enabling the assessment of photodegradation, color fading, embrittlement, and mechanical property changes.

2. What is the lamp lifetime and replacement schedule?

The UV fluorescent lamps have a rated lifetime of ≥5000 hours. Regular monitoring ensures consistent irradiance, and lamps should be replaced when output falls below the specified irradiance, ensuring test accuracy and repeatability.

3. What materials can be tested?

The chamber supports a wide range of materials including geosynthetics, plastics, coatings, inks, textiles, automotive materials, photovoltaic films, and outdoor decorative products. It is suitable for evaluating both mechanical and optical properties under accelerated aging conditions.

4. How is irradiance controlled?

Irradiance is monitored using a quantitative closed-loop system for 313 nm and 340 nm lamps, which automatically compensates for lamp aging and maintains uniform exposure across all samples, ensuring accurate and repeatable results.
