FAQ

1. What types of materials can be tested using the ATLAS UVTest Ultraviolet Weathering Test Chamber?

The ATLAS UVTest chamber is suitable for accelerated ultraviolet aging tests on a wide range of materials, including coatings, paints, inks, plastics, resins, adhesives, packaging materials, aluminum profiles, and automotive components. It is also commonly used in electronics, cosmetics, pharmaceutical packaging, and research applications. By combining UV exposure with controlled temperature and moisture conditions, the chamber helps evaluate material durability, surface degradation, and resistance to weathering effects.

2. How does black panel temperature (BPT) control contribute to test accuracy?

Black panel temperature control allows the chamber to simulate surface temperatures experienced by materials during real outdoor exposure. By directly controlling BPT during UV and condensation stages, the UVTest chamber ensures consistent thermal conditions across specimens. This improves test repeatability and allows meaningful comparison of results obtained under different test cycles or standards, particularly for coatings and polymer materials sensitive to temperature variations.

3. What safety features are integrated into the UVTest chamber?

The UVTest chamber incorporates multiple safety protection mechanisms, including hardware and software interlocks that stop operation when the door is opened, low water level protection, and over-temperature protection. These features help protect operators and equipment while maintaining stable test conditions. Compliance with CE requirements and certification by UL and CSA further confirms the chamber’s safety design.

4. How is irradiance controlled and verified during testing?

Irradiance is controlled through dedicated UV lamp configurations and can be adjusted within specified UVA and UVB ranges. A dedicated irradiance calibration safety interface and optional handheld calibration meter allow verification of light output. This ensures that exposure conditions remain within required tolerances for relevant international test standards.
