FAQ

1. What is the primary purpose of the SI220 Xenon Arc Weathering Test Chamber?

The SI220 is designed to evaluate textile light colorfastness and material aging performance by simulating natural sunlight and controlled climatic conditions using a xenon arc light source. By reproducing full-spectrum daylight along with temperature, humidity, and water spray, the chamber allows accurate assessment of color fading, performance change, and durability. This makes it suitable for predicting product service life under real environmental exposure conditions while maintaining high test repeatability and reproducibility.

2. How does the SI220 ensure accurate simulation of natural sunlight?

The chamber uses a 2200 W air-cooled xenon lamp combined with interchangeable optical filters and irradiance feedback control. This configuration enables precise control of irradiance at 420 nm or within the 300–400 nm range, closely matching the spectral distribution of natural sunlight. Multi-point energy monitoring and stable airflow further contribute to consistent and reliable light exposure throughout the test area.

3. What environmental parameters can be controlled during testing?

The SI220 provides automatic control of temperature, relative humidity, irradiance, and water spray. Chamber temperature can be set from 25 °C to 100 °C, while humidity is adjustable across different ranges for light and dark cycles. Black panel or black standard temperatures can also be controlled, allowing comprehensive simulation of various climatic conditions specified by international test standards.

4. What types of materials can be tested with the SI220?

The chamber is suitable for testing textiles, dyes, vulcanized rubber, and other materials requiring evaluation of lightfastness or artificial weathering performance. It is also applicable to printed materials and coated substrates where resistance to light exposure and environmental aging must be assessed under standardized laboratory conditions.
