In November 2023, LIB delivered the xenon lamp test chamber manufactured for EDF(Électricité de France S.A.), a French public power company, majority-owned by the French government and headquartered in Paris, France.
In April 2023, EDF sent test criteria and inquiry by mail for cable testing in accordance with EN 50483-6.
Wind turbines operate in harsh environments, which generally have a wide temperature range (about -40 °C to 50 °C) and are exposed to extremely strong ultraviolet radiation. Therefore, to achieve the expected service life, the special cable used needs to be able to withstand low temperatures of -40 °C and resist ultraviolet radiation. According to the requirements of customers, the measuring parts can withstand high intensity solar radiation at low temperatures.
LIB recommended XL-S-750C low temperature xenon test chamber, which meets the irradiation requirements and can reach -40 °C, meeting all the requirements proposed by the customer.

When testing materials for outdoor durability, accurate simulation of sunlight, heat, and humidity is essential. The LIB Xenon Arc Weatherometer replicates natural sunlight using 4500 W water-cooled xenon arc lamps with inner quartz and outer borosilicate filters, providing realistic exposure across the 280–800 nm spectrum. It delivers repeatable, standards-compliant results for plastics, coatings, films, and automotive components.
The chamber ensures precise environmental control with:
|
Heating Range |
Ambient ~ 100 °C ± 2 °C |
|
Black Panel Temperature |
35 ~ 85 °C ± 2 °C |
|
Humidity Range |
50 ~ 98 % RH |
|
Water Spray Cycle |
1 ~ 9999 H 59 M (Adjustable) |
|
Rotating Sample Holder |
1 r/min for uniform irradiance |
LIB's Xenon Arc Weatherometer complies with ASTM G151, G155, D6695, ISO 11341, and D7869, ensuring traceable and repeatable results. The system supports daylight, window-glass, and extended UV filters to simulate diverse sunlight conditions while maintaining black panel temperature and humidity cycling according to international test standards.
For coatings and automotive materials testing under ASTM G151, the LIB Xenon Arc Test Chamber precisely controls irradiance (0.30–1.10 W/m²·nm), black panel temperature (63–77 °C), and humidity (35–70 %), enabling reliable comparison of material durability and accelerated aging performance. Flexible exposure cycles, including illumination and spray phases, replicate real-world conditions such as dew, rain, and temperature fluctuations.
The chamber also features a closed-loop water recovery system, saving up to 80 % of water, along with real-time irradiance monitoring, PID temperature control, and programmable exposure profiles for complete traceability.
