Accelerated weathering testing plays a critical role in evaluating how materials withstand long-term outdoor exposure. Standards such as
ASTM International ASTM G155-21 provide guidelines for xenon arc exposure testing to simulate sunlight, humidity, and rain in a controlled laboratory environment. LIB Industry's xenon arc weathering chambers are designed according to this internationally recognized standard, delivering reliable and repeatable testing conditions.
Recently, a customer from the Philippines shared positive feedback after installing and relocating a LIB xenon arc weathering chamber to a new testing site. After the relocation, LIB's technical team followed up to confirm the equipment status.
The customer reported:
"It's okay! It's been running smoothly."
During daily operation, the customer also consulted LIB engineers about an IPX6 alarm notification. After technical guidance, it was clarified that the alarm is typically related to the chamber's water system. When the internal water temperature becomes too high during testing, the system automatically discharges hot water, requiring the tank to be refilled. LIB engineers recommended connecting an automatic water supply system to ensure continuous operation and prevent interruptions during long test cycles.
Advanced Xenon Arc Simulation Technology
LIB xenon arc chambers are engineered to replicate natural environmental conditions with high accuracy.
1. Full-Spectrum Xenon Light Simulation
The chamber uses a powerful 4500 W water-cooled xenon lamp to reproduce the full solar spectrum from 280–800 nm, including ultraviolet, visible, and infrared radiation. Interchangeable optical filters allow users to simulate various outdoor conditions such as direct sunlight or sunlight through window glass.
Compared with air-cooled systems, water-cooled xenon lamps maintain stable spectral output and remove excess heat efficiently, ensuring long-term stability in accelerated weathering tests.
2. Stable Irradiance and Temperature Control
ASTM G155-21 emphasizes accurate control of irradiance and specimen temperature. LIB chambers integrate a full-spectrum irradiance sensor and black panel temperature (BPT) sensor, managed by an advanced PID control system. This ensures stable light intensity and precise temperature regulation, improving test repeatability across long exposure cycles.
3. Realistic Humidity and Water Spray Simulation
In addition to sunlight, environmental aging also depends on moisture exposure. LIB xenon chambers feature an automatic deionized water supply system that supports humidification, spray, and xenon lamp cooling. The system simulates natural conditions such as dew, condensation, and rainfall, enabling more realistic durability testing for coatings, plastics, and automotive materials.

Intelligent Design for Efficient Testing
To ensure uniform exposure, the chamber uses a rotating sample rack capable of holding multiple specimens while maintaining consistent irradiance. Built-in sensors continuously monitor key parameters such as temperature and light intensity, ensuring compliance with ASTM G155 documentation requirements and providing full test traceability.
Additionally, LIB chambers support custom programmable exposure cycles, including light, dark, humidity, and spray phases. This flexibility allows laboratories to replicate real-world weather patterns according to different industry requirements.
Reliable Performance and Global Support
LIB Industry provides a 3-year warranty and lifetime technical support, along with global spare-parts availability and rapid delivery within 7–15 days. A 24-hour English-speaking technical support team ensures customers receive timely assistance whenever needed.
The positive feedback from the Philippine customer highlights the chamber's stable operation and LIB's responsive technical service. With advanced environmental simulation technology and reliable after-sales support, LIB xenon arc weathering chambers continue to support laboratories worldwide in validating the durability of materials under simulated sunlight and climate conditions.
