Xenon Arc Light Fastness Tester
Xenon Arc Light Fastness Tester
Xenon Arc Light Fastness Tester is a laboratory instrument used to evaluate the color fastness of textiles and materials when exposed to sunlight or artificial light. It simulates full-spectrum sunlight using a xenon arc lamp, making it ideal for assessing how materials resist fading over time.
Purpose of Xenon Arc Light Fastness Tester:
To determine how well a fabric or material maintains its color and integrity under prolonged light exposure, especially for outdoor or light-sensitive applications.
Working Principle of Xenon Arc Light Fastness Tester :
A xenon arc lamp emits light similar to natural sunlight. Fabric samples are exposed under controlled temperature, humidity, and light intensity. The degree of fading is compared to standard blue wool scales to assign a light fastness rating.
Main Components Xenon Arc Light Fastness Tester :
– Xenon Arc Lamp: Simulates sunlight (UV, visible, and infrared).
– Sample Holder: Rotates samples for uniform exposure.
– Environmental Controls: Maintains specific temperature and humidity.
– Control Panel/Software: Sets test parameters (light, time, humidity, etc.).
– Filters: Control the light spectrum (e.g., daylight, window glass).
Applications:
– Textiles
– Automotive interiors
– Plastics, paints, and coatings
– Outdoor fabrics and furnishings
Benefits of Xenon Arc Light Fastness Tester:

- Standard Compliance – Meets international standards like ISO 105-B02, AATCC TM16, and ASTM G155, ensuring globally accepted results.
- Improves Product Durability – Helps manufacturers assess and improve resistance to color fading, cracking, or degradation from light exposure.
- Versatile Applications – Suitable for testing textiles, plastics, paints, leather, and coatings.
- Controlled Test Conditions – Offers precise control over temperature, humidity, and light intensity, improving test consistency and repeatability.
- Supports Quality Assurance – Detects early failures in colorfastness, enabling better product design and material selection.
- Automated Operation – Programmable tests and automatic monitoring reduce operator involvement and errors.
- Accelerated Testing – Speeds up evaluation by simulating months or years of sun exposure in a few days or weeks.
Features of Xenon Arc Light Fastness Tester:
- Xenon Arc Lamp – Provides full-spectrum light (UV, visible, IR) to simulate natural sunlight accurately.
- Programmable Control System – Digital or touchscreen interface for setting test parameters like exposure time, temperature, humidity, and irradiance.
- Humidity and Temperature Control – Maintains precise environmental conditions inside the test chamber.
- Rotating Sample Carousel – Ensures uniform light exposure on all test specimens.
- Light Spectrum Filters- Adjustable filters simulate different light conditions (e.g., daylight, window glass, outdoor).
- Standards Compliance- Meets ISO, AATCC, ASTM, and other global test methods for light fastness.
- Automatic Irradiance Control – Maintains constant light intensity throughout testing, improving accuracy.
- Safety Features – Includes overheating protection, door interlock, and lamp monitoring system.
- Data Logging and Export – Some models offer USB or software integration for saving and analyzing test data.
- Durable and Insulated Chamber – Built with high-quality materials for stable testing and long-term use.
How to Use Xenon Arc Light Fastness Tester:
- Prepare the Samples
– Cut fabric or material into standard-size specimens.
– Label and condition samples (usually 24 hrs at 21°C, 65% RH).
- Mount the Samples – Attach samples onto holders or clips, placing them evenly on the rotating drum or carousel.
- Insert Blue Wool Standards- Include standard blue wool reference fabrics to compare light fastness.
- Set Test Parameters
– Use the control panel to set:
– Irradiance (e.g., 0.35 W/m² at 420 nm)
– Temperature and humidity
– Test duration (e.g., 24–72 hrs or more)
- Start the Test – Close the chamber door and begin the exposure cycle.
- Monitor Progress- System auto-adjusts irradiance and logs test conditions. Periodically check if needed.
- End and Remove Samples – After completion, stop the test and remove the samples and blue wool references.
- Evaluate Results – Compare the sample fading to the blue wool scale to assign a light fastness rating (1–8 scale).
