LIB Industry has launched a new customized Xenon Arc Test Chamber designed for customers requiring a different specimen layout and
larger testing space than conventional xenon arc weathering chambers. The new chamber adopts a small walk-in structure with a flat specimen placement design, while the xenon arc lamp is installed at the top of the chamber to provide direct and uniform exposure to the test specimens.
Unlike LIB's standard xenon arc chambers, which typically use a rotating sample rack, this customized design places the specimens horizontally and exposes them from above. This configuration provides greater flexibility for testing larger, heavier, or specially shaped materials that are not convenient to mount on a rotating rack.
The customized chamber is developed for accelerated weathering tests of plastics, coatings, automotive materials, building materials, outdoor products, and other materials that require long-term exposure to simulated sunlight, heat, humidity, and water spray.
【LIB Launches Customized Xenon Arc Weathering Test Chamber】
The new customized Xenon Arc Test Chamber retains the core functions required for xenon arc weathering testing while adapting the
chamber structure to the customer's specific testing requirements.
Small Walk-In Design: The walk-in structure provides more usable testing space while allowing operators to conveniently load and unload larger specimens.
Flat Specimen Placement: Unlike conventional rotating sample racks, the customized chamber uses a flat testing surface. This makes it suitable for large, heavy, irregularly shaped, or difficult-to-mount specimens.
Top-Mounted Xenon Arc Lamp: The xenon arc lamp is positioned above the test area, providing direct exposure to specimens placed horizontally below the light source.
Customized Testing Space: The chamber dimensions, specimen layout, sample fixtures, and exposure configuration can be customized according to the customer's material size and testing requirements.
Flexible Exposure Control: The system can be programmed for light, dark, water spray, humidity, and temperature cycles to reproduce different outdoor weathering conditions.
Customized Structure for Different Testing Requirements
The customized configuration gives laboratories more flexibility when standard rotating xenon arc chambers cannot accommodate their specimens.
For example, large panels, heavy components, sheets, coatings, and specially shaped materials can be positioned directly on the flat test area without requiring complex mounting fixtures. The walk-in design also provides easier access for loading, positioning, inspection, and removal of specimens.
The top-mounted lamp structure simplifies the exposure arrangement while maintaining controlled irradiance and specimen temperature throughout the test.
【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.
