OK-XD-1000 Xenon Arc Weathering Test Chamber

Overview

The OK-XD-1000 Xenon Arc Weathering Test Chamber is an engineered environmental simulation system designed to replicate the photothermal and hygrothermal stresses of natural sunlight exposure under controlled laboratory conditions. Utilizing a high-intensity air-cooled xenon arc lamp as its spectral source, the chamber delivers a continuous solar spectrum closely aligned with terrestrial AM1.5 global irradiance—covering critical UV-B (280–320 nm), UV-A (320–400 nm), visible (400–700 nm), and near-infrared (700–1100 nm) bands. This spectral fidelity enables accelerated aging studies for polymer degradation, pigment fading, coating delamination, and textile colorfastness evaluation. The chamber integrates precise temperature and humidity regulation with real-time black panel temperature monitoring—ensuring test reproducibility across international standards such as ISO 4892-2, ASTM G155, and IEC 60068-2-9. Its robust construction, dual-redundant safety architecture, and modular control interface make it suitable for R&D labs, QC departments, and third-party testing facilities operating under GLP or ISO/IEC 17025 frameworks.

Key Features

• High-fidelity xenon arc illumination system with quartz-filtered output matching CIE daylight reference spectra
• Independent temperature and humidity control loops with ±0.1°C thermal stability and ±1% RH humidity repeatability
• Dual-sensor black panel temperature monitoring (bimetallic type) for accurate surface heating assessment per ISO 4892-2 Annex A
• Automated water management system supporting both humidification and xenon lamp cooling circuits
• Weilun color touchscreen HMI paired with Siemens S7-1200 PLC for deterministic logic execution, programmable ramp-soak profiles, and event logging
• Stainless steel interior (SUS304) and electrostatically coated exterior housing for corrosion resistance and long-term structural integrity
• Low-noise, high-temperature centrifugal circulation fan ensuring uniform chamber airflow and minimizing thermal gradients
• Comprehensive safety suite including over-temperature cut-off, phase-loss detection, and door interlock circuitry

Sample Compatibility & Compliance

The OK-XD-1000 accommodates standard test specimens up to 75 mm × 150 mm on adjustable sample trays, allowing vertical or horizontal orientation per test method requirements. It supports specimen mounting using non-reactive aluminum or stainless steel fixtures compatible with ISO 4892-2 specimen holders. All operational parameters—including irradiance level (typically 0.35–0.55 W/m² @ 340 nm), chamber temperature (RT+10°C to +70°C), relative humidity (≥95% RH), and black panel temperature (up to +85°C)—are configurable within defined limits of relevant standards. The system’s design facilitates traceable calibration via NIST-traceable radiometers and PT100 temperature sensors. It meets essential electrical safety and EMC requirements per IEC 61000-4 series and supports audit-ready documentation for FDA 21 CFR Part 11–compliant environments when integrated with validated software extensions.

Software & Data Management

The embedded controller records time-stamped process data—including chamber temperature, humidity, black panel temperature, irradiance setpoint, and fault events—at user-defined intervals (1 s to 60 min). Raw logs are exportable in CSV format via USB or Ethernet. Optional PC-based software provides graphical trend analysis, comparative test reporting, and automated compliance flagging against ASTM G155 cycle definitions (e.g., Light-Dark, Light-Water Spray). Audit trail functionality—including operator login, parameter change history, and electronic signature capture—is available under validated configuration for regulated industries. All firmware updates are digitally signed and version-controlled to ensure integrity during maintenance cycles.

Applications

• Accelerated weathering validation of automotive interior trim, dashboards, and exterior coatings
• UV stability assessment of medical device packaging materials per ISO 11607
• Colorfastness and gloss retention testing for architectural paints and façade systems
• Photostability screening of pharmaceutical primary packaging (blister foils, HDPE bottles)
• Long-term durability qualification of photovoltaic encapsulants and backsheet films
• Material selection support for outdoor signage, agricultural films, and geotextiles

FAQ

What spectral filters are included with the OK-XD-1000?
Standard configuration includes Daylight-Q filter (matching ISO 4892-2 Option A) and Window Glass-Q filter (Option B); additional filters available upon request.
Is irradiance calibration performed at installation?
Yes—a certified radiometric calibration report (traceable to NIST) is provided with each unit, including baseline measurements at 340 nm and 420 nm.
Can the chamber operate without humidity control?
Yes—humidity can be disabled while maintaining temperature and irradiance control, enabling dry-heat UV exposure protocols per ASTM D4329.
What maintenance intervals are recommended for the xenon lamp?
Lamp life is rated at 1500 hours under standard operation; replacement is required after 1200–1500 h or when irradiance drops below 90% of initial output.
Does the system support remote monitoring?
Native Ethernet connectivity enables Modbus TCP integration with building management systems or centralized lab monitoring platforms.
