Outdoor products face years of sunlight, rain, humidity, and temperature changes throughout their service life. Waiting several years to evaluate material durability is impractical for manufacturers. This is why accelerated weathering testing has become an essential part of product development and quality control.

This article explains how long LIB typical test takes in a Xenon Lamp Aging Test Chamber, which standards determine testing duration, which industries benefit most from xenon testing, and why leading organizations such as Electricite De France selected LIB's customized xenon weathering solution for critical cable performance verification.

1. ASTM G155 Exposure Cycles and Typical Test Duration

ASTM G155 is one of the world's most widely recognized standards for xenon arc weathering testing. It specifies the use of xenon arc lamps to simulate full-spectrum sunlight, including ultraviolet (UV), visible light, and infrared radiation.

Unlike pass/fail standards, ASTM G155 provides exposure methods and test cycles. Typical testing durations include:

① 500 hours for preliminary material screening

② 1000 hours for coating and plastic durability evaluation

③ 1500–2000 hours for automotive exterior materials

④ 3000 hours or longer for high-reliability outdoor applications

For example, ASTM G155 Cycle 1 commonly uses:

① 102 minutes light exposure

② 18 minutes light exposure with water spray

③ Black Panel Temperature (BPT): 63°C

Under these conditions, manufacturers can simulate years of outdoor weather exposure within several weeks or months.

High-Precision Xenon Light Simulation

ASTM G155 requires xenon arc lamps to reproduce the full spectrum of natural sunlight, including ultraviolet, visible, and infrared wavelengths. LIB Xenon Lamp Aging Test Chamber is equipped with a 4500W water-cooled xenon lamp and professional optical filter system, providing a spectral range of 280–800 nm. The chamber accurately simulates real outdoor sunlight conditions, making it suitable for weathering tests on plastics, coatings, cables, automotive parts, and construction materials.

Accurate Irradiance and Temperature Control

To meet ASTM G155 requirements, irradiance and specimen temperature must remain stable throughout the test. LIB integrates a full-spectrum irradiance sensor and Black Panel Temperature (BPT) monitoring system. Combined with intelligent PID control technology, the chamber continuously adjusts operating conditions to maintain precise light intensity and temperature, ensuring highly repeatable and reliable test results over long exposure periods.

Automatic Moisture and Spray Simulation

ASTM G155 emphasizes the importance of moisture exposure when evaluating outdoor durability. LIB Xenon Lamp Aging Test Chamber includes automatic humidity control and water spray systems that simulate rain, dew, and condensation. The integrated deionized water supply system supports continuous operation while reducing maintenance requirements. By combining sunlight, humidity, and water spray in a single test cycle, the chamber provides a more realistic simulation of natural weathering environments.

Water-Cooled Design for Long-Term Stability

Compared with conventional air-cooled xenon systems, LIB's water-cooled design removes heat more efficiently and maintains a more stable light spectrum during extended testing. This reduces irradiance fluctuations, extends xenon lamp service life, and improves overall testing consistency. For long-duration weathering programs ranging from 1000 to 3000 hours or more, stable operation is essential for generating dependable aging data.

Flexible Programming for ASTM G155 Test Cycles

Different products often require different exposure conditions. LIB chambers support fully programmable test profiles, allowing users to create customized sequences of light exposure, water spray, humidity control, and temperature changes. Whether following ASTM G155 Cycle 1, ISO 4892-2 procedures, or customer-specific requirements, the chamber can automatically execute complex weathering programs while maintaining precise control of all critical parameters.

3. Which Industries Need Long-Term Xenon Weathering Tests?

xenon Lamp Aging Test Chamber and Achieved Excellent Results

In April 2023, Electricite De France, one of Europe's largest electricity transmission organizations, contacted LIB with a testing requirement for cable performance evaluation according to EN 50483-6.

The customer needed:

• Accurate solar radiation simulation

• Stable low-temperature operation

• Long-term reliability testing

• Compliance with international standards

After reviewing the testing requirements, LIB recommended the customized XL-S-750C Low-Temperature Xenon Lamp Aging Test Chamber.

Key specifications included:

① Temperature range down to -40°C

② ASTM G155 compliant xenon light system

③ Precise irradiance control

④ Automatic humidity and spray functions

⑤ Large-capacity sample area

The Xenon Lamp Aging Test Chamber successfully met the irradiance requirements specified in EN 50483-6 while providing low-temperature environmental simulation not commonly available in standard xenon chambers.

In November 2023, the customer received the equipment and completed installation successfully.

Several advantages received positive feedback:
