Xenon Arc Light Fastness and Weathering Tester

Name: Xenon Arc Light Fastness and Weathering Tester
Brand: Xi'an LIB Environmental Simulation Industry

A xenon arc light fastness and weathering tester uses a xenon arc lamp as light source to simulate full-spectrum sunlight, reproducing UV, visible, and infrared wavelengths for accelerated aging evaluations. The system typically offers adjustable irradiance from 35–150 W/m², BPT control 35–85°C, workroom temperature ambient–100°C, relative humidity 50–98% RH, and programmable water spray / moisture condensation cycles,the coordination of temperature and humidity, spray and other systems can accelerate the aging of materials and quickly show the performance changes in long-term outdoor environment.

This xenon arc tester complies with major global standards, including ISO 4892-2, ASTM G155, AATCC TM16, SAE J2527, and etc, ensuring test credibility for international product certification.

The xenon weathering tester is commonly used to evaluate colorfastness, gloss retention, surface cracking, chalking, strength loss, and material aging across industries such as automotive interiors/exteriors, coatings, plastics, rubbers, textiles, packaging, building materials, and photovoltaic components.

Model: XL-S-750 and more customized models

Standard: IEC 60068-2-5, IEC 60068-2-27,ASTM G26,ISO 105, ISO 4892-2, ASTM G155, ASTM G151, ASTM G155,ISO 105-B02 (EN) (DIN), ISO 105-B04 (EN) (DIN).

Features and Benefits of Xenon Arc Light Fastness and Weathering Tester

1. True Full-Spectrum Sunlight Simulation

Using a xenon arc lamp, the tester reproduces UV, visible, and infrared radiation that closely matches natural daylight. This ensures results that accurately reflect real outdoor environmental exposure, providing reliable predictions of long-term material performance.

2. Accelerated Aging with Precise Environmental Control

Independent control of irradiance, black panel temperature, chamber temperature, humidity, and water spray/condensation cycles allows highly repeatable conditions for accelerated light and weather aging tests.

3. Compliance with International Standards

Fully aligned with test requirements such as ISO 4892-2, ASTM G155, AATCC TM16, and SAE J2527. This guarantees test consistency and supports global certification, supplier qualification, and production quality assurance.

4. Energy-Efficient Cooling and Lamp System

Optimized airflow design and high-efficiency water cooling reduce heat load and extend xenon lamp lifespan to 1600 hrs, lowering operating costs and improving long-duration stability for demanding test schedules.

5. Modular Configurations and Customizable Test Profiles

User-defined test programs allow customized cycles for sunlight exposure, humidity, dark periods, and water spray — ideal for comparing materials, simulating specific climates, or recreating end-user environmental conditions for R&D validation.
