FAQ

1. What makes the Xenotest 440 suitable for high-irradiance weathering tests?

The Xenotest 440 uses XenoLogic™ dual-lamp operating technology, which allows the system to reach irradiance levels up to 120 W/m² in the 300–400 nm wavelength range. This high UV output enables accelerated testing while maintaining stable exposure conditions. At the same time, the dual-lamp configuration distributes operating load between lamps, supporting consistent performance across extended test durations.

2. How does XenoLogic™ technology extend xenon lamp service life?

XenoLogic™ technology optimizes the operation of two xenon lamps by alternating and balancing their usage. Under standard test conditions of 40–60 W/m², this approach allows the lamps to operate for more than 4000 hours. Extended lamp life reduces maintenance frequency and operating costs while preserving stable irradiance and reproducible test conditions throughout long-term testing programs.

3. What specimen configurations are supported by the Xenotest 440?

The Xenotest 440 supports multiple specimen sizes and configurations through its rotating specimen rack. Depending on specimen dimensions, the chamber accommodates 38. 33. 22. or 11 test positions. This flexibility allows efficient testing of textiles, plastics, coatings, and automotive materials within the same system while maintaining uniform exposure conditions.

4. How are temperature and humidity controlled during testing?

Temperature control includes direct regulation of black standard temperature, black panel temperature, and chamber air temperature, with optional dual control modes reaching up to 115 °C. Relative humidity during light cycles is controlled between 10% and 75% using an ultrasonic humidification system. These combined controls ensure stable environmental conditions aligned with international test standards.
