A Qualitest xenon arc test chamber recreates daylight exposure, heat, and moisture to examine how manufactured materials break down over time. Each xenon test chamber simulates real-world conditions by managing light emission, surface temperature, and humidity for specimen evaluations. We build these systems for technical teams evaluating coatings, polymers, textiles, and automotive parts across commercial facilities.

Xenon Arc Test Chamber Overview
A xenon arc test chamber speeds up the natural degradation of materials by reproducing full-spectrum daylight alongside heat and moisture. Inside the enclosure, an air-cooled or water-cooled gas-discharge lamp in a quartz tube projects continuous light across your test pieces.
Humidifiers supply moisture while internal heating elements regulate sample and chamber temperatures. These instruments help quality engineers observe premature color fading, surface cracking, and chalking under repeatable laboratory conditions.
At Qualitest, we configure these cabinets with exposure surfaces spanning from 1,000 square centimeters up to 6,500 square centimeters. The apparatus tracks light intensity through automated closed-loop systems at targeted wavelengths such as 340 nm and 420 nm, adjusting output to offset natural burner aging. This continuous regulation keeps the overall xenon test consistent from the start of an evaluation through to completion.
Compliance & Standards
Qualitest builds every xenon test chamber to align with globally accepted accelerated weathering specifications. For worldwide testing laboratories handling polymer, textile, and coating evaluations, primary benchmarks include ISO 4892-1 and ISO 4892-2 for plastics, alongside ASTM G151 and ASTM G155 for nonmetallic materials. Surface-treatment and paint evaluations follow ASTM D6695 and ISO 16474-2.
Automotive component assessments also align with international vehicular criteria like SAE J2412 and SAE J2527. Depending on the model selected, our test cabinets support specialized international procedures including ISO 11341, ISO 12040, ASTM D3451, ASTM D4303, ASTM D6577, ASTM C1442, and ISO 4049. This multi-standard compliance gives testing facilities the ability to deliver audit-ready data recognized by international quality inspection bodies.
Key Features
- Xenon Light Source and Optical Filtration: Cabinets run single or triple American-made xenon burners ranging from 1.8 kW to 6.5 kW in air-cooled or water-cooled designs. Paired with daylight, window glass, or extended UV filters, the optical system allows you to simulate direct exterior sunlight or filtered indoor radiation for xenon arc uv testing.
- Specimen Capacity and Exposure Surface: Configurations provide exposure areas from 1,000 cm2 on compact benchtop units up to 6,500 cm2 on floor-standing models. This accommodates between 9 and 65 standard test specimens (150 mm x 70 mm), allowing laboratories to match equipment capacity to routine sample throughput.
- Closed-Loop Irradiance Management: Automated sensors monitor narrow wavelengths (340 nm or 420 nm) or broad spectrums (300 to 400 nm and 300 to 800 nm). The system automatically counteracts lamp aging degradation, delivering stable radiation for tests running up to 2,000 hours.
- Corrosion-Resistant Enclosure and Thermal Sensors: Interiors feature SUS304 or SUS316 stainless steel to resist persistent humidity. Built-in Pt100 probes regulate Black Panel Temperatures up to 110 °C and Black Standard Temperatures up to 120 °C with ±1 °C stability for repeatable thermal stress.
- Controlled Moisture and Surface Spray: Front and rear spray nozzles pair with high-pressure ultrasonic humidifiers to sustain relative humidity levels up to 95%. This setup reproduces rain, dew, and condensation cycles to identify paint blistering or material spalling.
- Programmable Logic Controls and Data Export: Systems use Siemens PLC touch-screen interfaces capable of storing up to 9,999 programmable sequences. Real-time run data transfers via USB in Excel format, while built-in safety interlocks automatically shut off the lamp if an operator opens the access door.
Product Applications & Operating Environments
In commercial and industrial laboratories, technicians use a xenon test chamber to evaluate the service life of finished goods and raw materials. Documented production applications include:
- Paints and Protective Coatings: Identifying gloss reduction, color shift, coating peel, and surface chalking.
- Automotive Exterior and Interior Trims: Testing lightfastness on dashboard polymers and clarity retention in laminated vehicle safety glass.
- Plastics and Polymer Additives: Checking resistance to photo-oxidation, thermal embrittlement, and stress cracking.
- Adhesives, Wood Treatments, and Textiles: Inspecting bond durability, veneer discoloration, and fabric dye fading.
These instruments are intended exclusively for controlled indoor facility settings. Installation requires a dedicated testing room with at least 12 square meters of floor space and a ceiling clearance of at least 2.8 meters. The laboratory must provide continuous air conditioning maintaining ambient temperatures between 22 °C and 30 °C, humidity between 30% and 80%, oil-free compressed air at 0.5 MPa, and deionized water with electrical conductivity below 2 µS/cm.
The chamber environment does not recreate abrasive sand, wind speed, or biological mold growth. Regular verification with external instruments like the QualiRadiometer 1000 ensures irradiance sensors maintain calibration within target margins.
