Xenon Arc Weathering Test Chamber for Material Aging Tests

Product Applications (Applications)

A Xenon Lamp Aging Test Chamber is designed to simulate full-spectrum sunlight using a xenon arc lamp, enabling accelerated aging evaluation of materials exposed to outdoor environments. It helps manufacturers assess color stability, aging resistance, and durability under light, temperature, humidity, and rain conditions.
 

Typical Applications

Lightfastness & Weathering Tests

Evaluate color fading, gloss loss, cracking, and mechanical degradation under long-term light exposure.

Automotive Materials

Testing automotive textiles, plastic trims, dashboards, rubber seals, coatings, and interior parts.

Plastics & Rubber

PE, PP, PVC, ABS, silicone rubber, sealing rings, outdoor plastic parts.

Coatings & Paints

Powder coatings, automotive coatings, industrial coatings, wood coatings.

Textiles & Dyes

Lightfastness testing for fabrics, upholstery fibers, dyed materials.

Construction Materials

PVC boards, exterior wall panels, flooring, waterproof materials.

Electronics & Optical Components

Plastic housings, light-transmitting materials, lenses, display covers.

Frequently Asked Questions (FAQ)

Q1: What is the purpose of using a xenon arc lamp?

A xenon arc lamp simulates the full spectrum of natural sunlight, including UV, visible, and infrared radiation. This enables accurate prediction of outdoor product aging.

Q2: What materials can be tested in a xenon aging chamber?

It is suitable for plastics, rubber, textiles, leather, coatings, automotive parts, packaging materials, and construction materials.

Q3: How long is one standard test cycle?

Test cycles vary depending on the standard:

ISO 4892: typically 102 minutes of light + 18 minutes of light & spray

ASTM G155: multiple cycle options

The testing period can range from 24 hours to 1,000+ hours depending on aging requirements.

Q4: Is water spray necessary during testing?

Yes. Many weathering standards require water spray or rain simulation to replicate natural erosion, thermal shock, and humidity cycling.

Q5: What type of filters are used in xenon lamps?

Different filters simulate different natural environments:

Daylight filters — outdoor exposure

Window glass filters — indoor sunlight exposure

Extended UV filters — special accelerated tests

Q6: How often should the xenon lamp be replaced?

Typically every 1,500–2,000 hours, depending on the model and intensity.

Q7: Do xenon chambers require external water purification?

Yes. Most chambers require deionized (DI) or purified water to ensure accurate humidity and spray functions.
