Xenon Arc UV Testing is an advanced accelerated weathering test used to evaluate how materials respond to prolonged exposure to sunlight, heat, and moisture. This testing method closely simulates real outdoor environmental conditions, making it one of the most reliable ways to predict long-term material performance.
Industries such as plastics, automotive, coatings, textiles, packaging, rubber, and construction rely on xenon arc testing to ensure product durability, color stability, and resistance to degradation. Presto Group offers high-precision xenon arc weathering test chambers designed to meet international testing standards and industry requirements.
What Is Xenon Arc UV Testing?
Xenon arc testing uses a xenon arc lamp to reproduce the full spectrum of natural sunlight, including ultraviolet (UV), visible, and infrared radiation. By combining light exposure with controlled temperature, humidity, and water spray or condensation cycles, the test accelerates the aging process of materials.
This allows manufacturers to observe changes that would normally occur over months or years in real outdoor environments within a much shorter time frame.
Why Xenon Arc Testing Is Important
Exposure to sunlight and environmental factors can cause materials to fade, crack, become brittle, lose strength, or change color. Xenon arc UV testing helps manufacturers:
-
Predict long-term outdoor performance
-
Evaluate color fastness and gloss retention
-
Identify material degradation and failure modes
-
Compare formulations or coatings
-
Ensure compliance with global standards
-
Reduce warranty claims and product failures
How Xenon Arc UV Testing Works
A xenon arc weathering tester subjects samples to controlled cycles of:
-
Light Exposure: Simulates natural sunlight
-
Temperature Control: Accelerates thermal aging
-
Humidity and Moisture: Mimics rain, dew, and condensation
-
Water Spray (Optional): Reproduces weather effects
These combined stresses accelerate the aging process while maintaining high correlation with real-world exposure.
Key Properties Evaluated
Xenon arc UV testing helps assess:
-
Color change and fading
-
Tensile strength loss
-
Surface cracking and chalking
-
Yellowing and discoloration
-
Gloss reduction
-
Coating adhesion failure
Common Testing Standards
Xenon arc UV testing is conducted according to internationally recognized standards, including:
-
ASTM G155 – Xenon arc light exposure of non-metallic materials
-
ISO 4892-2 – Plastics exposure to xenon arc light
-
SAE J2527 / J2412 – Automotive interior and exterior testing
-
AATCC TM16 – Textile colorfastness to light
Presto Group xenon arc test chambers are fully compliant with these global standards.

Xenon Arc UV Testing vs. Fluorescent UV Testing
While fluorescent UV testing focuses mainly on short-wavelength UV exposure, xenon arc testing offers a full-spectrum simulation, making it ideal for products exposed to real outdoor conditions. Xenon arc testing provides more realistic and comprehensive results, especially for color-sensitive and appearance-critical materials.
