ASTM G155 UV Test Chamber

Looking for a reliable solution to meet ASTM G155 light aging standards? LIB's advanced UV test chambers deliver precise spectral simulation, stable irradiance control, and flexible test programming to ensure high-performance weathering results.

ASTM G155 Conformance Features of LIB UV Test Chamber

Irradiance and Spectral Matching

• Standard full-spectrum xenon arc lamp covering the 280–800 nm wavelength range, accurately simulating the UV and visible light spectrum of sunlight.
• Built-in radiometer for real-time monitoring of black panel temperature (BPT) irradiance, compliant with ASTM G155 requirements of 0.35 W/(m²·nm) (340 nm) or 1.10 W/(m²·nm) (420 nm), with fluctuations controlled within ±0.02 W/(m²·nm).

Precise control of black panel temperature (BPT)

• Multi-point temperature sensors combined with a PID controller maintain the black panel temperature within ±2 °C in modes such as 63±3 °C and 70±1 °C;
• An automatic xenon lamp water-cooling system ensures uniform and stable temperature throughout the entire test cycle.

Spray/wet cycle simulation

• An independent water supply system supports front/back spraying of samples, with a spray rate adjustable up to 0.35 ml/cm²·min;
• Spray and drying cycles can be freely set (1 min–9999 h 59 min), fully compliant with multiple light-wet cycle schemes specified in the ASTM G155 standard.

Precise Spectral Simulation and Irradiance Control in LIB UV Test Chamber

Full-spectrum high-fidelity simulation

Utilizes high-energy xenon arc lamps + filters. Three types of filters include Window glass, Daylight, and UV extended. The spectral power distribution closely matches real light, accurately reproducing both short and long wavelengths.

Precise light control

The irradiance meter automatically synchronizes with the BPT system. The water-cooled xenon lamp tube maintains irradiance fluctuations within ±3%.

Energy-saving and environmentally friendly design

Condensate water recovery system: spray water and lamp cooling water are recycled, achieving a water-saving rate of up to 30%. 4500W/6500W xenon arc lamps operate for 1600 hours to meet testing requirements.

Data management and export

• The PID controller's color touchscreen allows editing of over 100 test programs, with each segment independently setting irradiance, BPT temperature, and spray mode.
• Supports USB/Ethernet export of raw irradiance/temperature/humidity/spray data, facilitating quality traceability and third-party audits.

LIB Accelerated Weathering Series: Xenon, UV, & Preconditioning Chambers

Xenon Arc Test Chamber

• Spectral Coverage: 280–800 nm full spectrum simulation, corresponding to natural light with full UV/visible coverage.
• Application Scenarios: Testing of outdoor plastics, coatings, building materials, etc., requiring full-spectrum light aging; short-cycle assessment of fading, cracking, chalking, and other phenomena.

UV Weathering Test Chamber

• Focused UV Band: 300–400 nm narrowband high-stability output, combined with spray and humidity cycling, to achieve UV-specific aging of materials such as plastics, coatings, and textiles.

UV Preconditioning Chamber

• Purpose: To perform preconditioning of photovoltaic panel samples at a temperature of 60°C ±5°C while subjected to UV irradiation, ensuring test consistency and sample stability prior to formal light aging.
• Features: Both UVA and UVB bulbs are utilized for all accelerated weathering test methods as requested in the UV preconditioning test.

The above are the core advantages and application scenarios of the LIB accelerated aging series in terms of ASTM G155, spectral simulation, and product series, helping you achieve more accurate, efficient, and environmentally friendly material weathering testing.
