ASTM G155 Xenon Arc Weathering Testing
When conducting accelerated aging tests, selecting the right test chamber is critical. ASTM G155-21 is an internationally recognized standard specifically developed for xenon arc exposure testing. It outlines how to scientifically simulate real-world conditions such as sunlight, humidity, and rain to evaluate a material's resistance to long-term outdoor use.
LIB's ASTM G155 xenon arc weathering chambers are engineered in strict accordance with this standard, ensuring reliable, repeatable results that align with globally accepted testing norms.
【How Does LIB Xenon Arc Chamber Simulate Real Weather?】
High-Fidelity Light System That Mimics Natural Sunlight
ASTM G155-21 requires the use of specially filtered xenon arc lamps to reproduce the full spectrum of sunlight, including UV, visible, and infrared radiation. LIB utilizes a powerful 4500W water-cooled xenon lamp, with interchangeable filters (e.g., daylight, window glass types) to match different environmental conditions. The system ensures spectral coverage from 280–800 nm, fully meeting the standard's light spectrum simulation requirements.
Compared to air-cooled systems, water cooling removes heat quickly and maintains the stability of the xenon lamp's light spectrum. By combining Black Panel Temperature (BPT) control with spectrum-specific radiometers, the system ensures precise light and temperature regulation, enabling more accurate and efficient results in plastic aging tests.
This intelligent water supply system is designed for sustainability, automatically delivering water to the spray, humidification, and xenon lamp cooling systems. It features condensate recovery, precise refilling, and partial recycling functions, significantly reducing water consumption and supporting environmentally responsible testing operations.
Stable Temperature and Irradiance for Reproducible Testing
The standard G155 emphasizes precise control of irradiance and specimen temperature. LIB's chamber integrates a full-spectrum irradiance sensor and black panel temperature sensor, governed by an advanced PID control system. This ensures spectral stability and high data consistency over long test periods, enabling reliable inter-lab comparisons.
Humidity and Water Spray to Simulate Dew, Rain, and Condensation
In addition to light, G155 highlights the importance of moisture exposure through condensation and water spray. LIB chambers feature an automatic deionized water supply system for spray, humidification, and cooling. A built-in condensation cycle enhances energy efficiency while accurately reproducing natural moisture cycles.
【Meeting the Requirements of ASTM G155-21】
Supports Standard Exposure Cycles
While ASTM G155 does not define specific pass/fail results, it provides recommended test cycles such as Cycle 1 (commonly used for coatings and automotive components). LIB chambers support custom programming of exposure sequences including light/dark, spray, and humidity phases.
Uniform Exposure with Real-Time Monitoring
A rotating sample rack ensures uniform irradiance across up to 42 specimens. Built-in sensors continuously monitor critical parameters like light intensity and temperature, in compliance with Section 10 of G155 regarding test documentation and data traceability.
