Overview
The Yuelian YL-XD1000LA Xenon Arc Weathering Test Chamber is an engineered environmental simulation system designed to accelerate material degradation under controlled exposure to full-spectrum solar radiation, temperature, humidity, and moisture cycling. It employs a water-cooled, long-arc xenon lamp emitting continuous radiation across 290–1200 nm — closely replicating terrestrial sunlight when paired with precision optical filters. This enables quantitative assessment of photostability, color fading, chalking, cracking, gloss loss, and mechanical property deterioration in polymeric, organic, and composite materials. Unlike narrowband UV chambers, the YL-XD1000LA delivers spectrally accurate irradiance in the UV-A (315–400 nm), visible (400–700 nm), and near-infrared (700–1200 nm) regions — critical for evaluating real-world outdoor durability and indoor light-induced aging (e.g., retail lighting, automotive interiors). The chamber complies with fundamental photometric calibration requirements per ISO 4892-2 and ASTM G155, ensuring traceable spectral power distribution and irradiance uniformity across the test plane.
Key Features
- Water-cooled 6.5 kW xenon arc lamp with integrated voltage/current regulation for stable irradiance output and automatic energy compensation
- Programmable irradiance control in key UV bands: 30–120 W/m² (300–400 nm), 0.3–1.0 W/m² (340 nm), and 0.8–1.5 W/m² (420 nm)
- Black panel temperature sensor with ±3 °C accuracy and adjustable setpoint (up to 65 °C) for surface heating simulation
- Full-range relative humidity control (30–98 %RH) with platinum resistance (PT100) sensors and steam-based humidification

- Motor-driven sample rotation carousel (≥1 rpm, stepless) ensuring uniform exposure across irregularly shaped specimens
- Robust thermal management: dual French Tecumseh industrial compressors, R404A refrigerant, and forced-air heat exchange
- Stainless steel (SUS304) interior chamber with high-efficiency polyurethane + glass fiber insulation; non-condensing external surfaces
- 7-inch full-color TEMI2700 touchscreen controller supporting up to 120 programs / 1200 segments, PID auto-tuning, and USB data logging
Sample Compatibility & Compliance
The YL-XD1000LA accommodates flat, curved, or three-dimensional samples up to standard dimensions via adjustable stainless steel specimen racks and custom mounting fixtures. Its irradiated area (~7500 cm²) and lamp-to-sample distance (350–380 mm) meet spatial uniformity requirements defined in ISO 4892-2 Annex B. The system supports compliance with over 15 international standards including: ASTM D2565 (plastics), ASTM D4329 (paints), ISO 11341 (rubber), ISO 105-B02 (textiles), GB/T 16422.2 (China national standard for plastics), GB/T 8427 (textile colorfastness), and GB/T 1865 (coatings). Optional configurations enable adherence to FDA 21 CFR Part 11-compliant audit trails when integrated with validated software environments. All humidity and temperature controllers are calibrated to NIST-traceable references, and irradiance sensors are periodically verifiable against certified reference cells per ISO/IEC 17025 laboratory practice.
Software & Data Management
The TEMI2700 controller provides embedded data acquisition at 1-second resolution for irradiance, black panel temperature, chamber air temperature, and relative humidity. Real-time PV curve visualization (0–8 days history), alarm event logging with timestamps, and configurable digital outputs support GLP/GMP-aligned documentation workflows. USB storage (UDC100-compatible) allows export of CSV-formatted test reports, program archives, and calibration logs. RS485/Modbus RTU interface enables integration into centralized LIMS or MES platforms. Firmware supports firmware-level password protection, user access levels (operator/engineer/admin), and automatic backup of all parameter settings to internal flash memory (retention >10 years). No proprietary drivers or cloud dependencies are required — all functions operate autonomously on the embedded microcontroller.
Applications
This chamber serves as a primary tool for accelerated weathering validation across regulated and industrial sectors. In automotive R&D, it evaluates dashboard polymers, exterior trim coatings, and headlamp lenses under SAE J2527 cyclic protocols. For packaging development, it quantifies UV barrier efficacy of multilayer films and printed inks per ASTM D7209. In pharmaceuticals, it supports ICH Q1B photostability testing of drug substances and primary packaging under Option 2 (xenon lamp) conditions. Building material manufacturers use it to qualify roofing membranes, sealants, and façade composites per ASTM D4459 and EN 1297. Quality assurance labs deploy it for incoming raw material screening, batch-to-batch consistency verification, and failure root cause analysis following field complaints. Its ability to decouple UV intensity from thermal load makes it uniquely suitable for studying photochemical vs. thermally driven degradation mechanisms.
FAQ
What standards does the YL-XD1000LA comply with?
It meets core requirements of ISO 4892-2, ASTM G155, ASTM D2565, GB/T 16422.2, and multiple textile, coating, and rubber aging standards listed in its technical documentation.
Can the chamber simulate indoor lighting conditions?
Yes — by selecting appropriate filter combinations and reducing irradiance output, it replicates fluorescent, halogen, and LED spectra relevant to retail, museum, and office environments.
Is humidity control mandatory during irradiation cycles?
No — humidity can be deactivated independently while maintaining UV exposure, enabling dry-heat or dark-cycle conditioning per test protocol requirements.
How often must the xenon lamp be replaced?
At nominal irradiance (e.g., 0.55 W/m² @ 340 nm), lamp life averages 1600 hours; replacement is indicated when irradiance drift exceeds ±5 % of setpoint or spectral output degrades beyond filter tolerance limits.
Does the system include radiometric calibration support?
Yes — it ships with a factory-calibrated broadband irradiance sensor and provides mounting provisions for NIST-traceable reference cells used in periodic verification.
