Jianhu JH-Series Xenon Arc Weathering Test Chamber with Integrated Light-Temperature-Humidity Control

Overview

The Jianhu JH-Series Xenon Arc Weathering Test Chamber is an engineered environmental simulation system designed for accelerated material aging evaluation under controlled solar-spectrum irradiation, temperature, and relative humidity. It operates on the principle of xenon arc lamp-based spectral replication—utilizing high-pressure xenon lamps coupled with precision optical filters (e.g., Daylight-Q, Window Glass-Q) to reproduce the full solar spectrum (290–2500 nm), including biologically active UV-B (280–315 nm), UV-A (315–400 nm), visible (400–700 nm), and near-infrared (700–2500 nm) radiation. Unlike fluorescent UV or metal halide systems, xenon arc technology delivers spectrally stable, broadband illumination that closely matches terrestrial sunlight, enabling physiologically and chemically relevant degradation pathways in polymers, coatings, textiles, automotive interiors, and packaging materials. The chamber integrates real-time feedback control loops for irradiance (via calibrated UV/visible radiometers), black panel or black standard thermometer (BST) temperature, and chamber air RH—ensuring traceable, repeatable exposure conditions compliant with ISO 4892-2, ASTM G155, SAE J2527, and IEC 60068-2-9.

Key Features

• High-fidelity solar spectrum simulation using water-cooled or air-cooled 1.8–6 kW xenon arc lamps with interchangeable filter assemblies for daylight, window-glass-filtered, or extended-UV configurations
• Independent yet synchronized control of irradiance (150–736 W/m², adjustable in 1 W/m² increments), chamber air temperature (−40°C to +100°C, ±0.5°C stability), and relative humidity (20–95% RH, ±2% RH accuracy)
• Dynamic light-temperature-humidity coupling algorithm: enables programmable ramp-and-soak profiles where irradiance intensity modulates chamber thermal load and moisture saturation in real time—mimicking diurnal cycles, seasonal transitions, or extreme climatic events
• Robust stainless-steel interior with quartz viewing window, corrosion-resistant sample racks, and optional specimen rotation mechanisms for uniform exposure
• Compliance-ready architecture: supports audit trails, user access levels, electronic signatures, and data export formats compatible with FDA 21 CFR Part 11 and GLP/GMP documentation requirements

Sample Compatibility & Compliance

The JH-Series accommodates flat-panel specimens up to 600 mm × 600 mm (customizable), cylindrical automotive trim parts, textile swatches, and multi-layer laminates. Sample holders are designed for zero-shadow geometry and thermal decoupling to prevent localized overheating. All operational parameters—including irradiance setpoint, BST temperature, chamber RH, and exposure duration—are validated against international reference standards. Calibration certificates traceable to NIM (National Institute of Metrology, China) or NIST-equivalent laboratories are available upon request. The system meets mechanical and electrical safety requirements per IEC 61000-6-2/6-4 and carries CE marking. For regulated industries, optional IQ/OQ documentation packages align with ISO/IEC 17025 laboratory accreditation criteria.

Software & Data Management

Equipped with Jianhu’s proprietary WinTest Pro v4.2 control software, the chamber provides intuitive graphical programming of multi-step exposure cycles (e.g., 4-h UV + 4-h condensation + 4-h dark chill), real-time parameter trending, and automated pass/fail evaluation against pre-defined thresholds. Data logging occurs at 1-second intervals and is stored in encrypted CSV and XML formats. Export modules support direct integration with LIMS platforms and statistical process control (SPC) tools such as Minitab and JMP. Audit trail functionality records all operator actions, parameter modifications, and calibration events with timestamps and user IDs—fully satisfying FDA 21 CFR Part 11 electronic record integrity requirements. Remote monitoring via Ethernet or optional 4G LTE module enables off-site supervision without compromising data security.

Applications

This test chamber serves critical roles across R&D, quality assurance, and regulatory submission workflows. In automotive OEM supply chains, it validates color fade resistance (ΔE*), gloss retention, and cracking behavior of dashboards and exterior trims per SAE J2412. In photovoltaics, it assesses encapsulant yellowing and adhesion loss in PV modules under IEC 61215-2 MQT03. Coating manufacturers use it to rank UV stabilizer efficacy in architectural paints (ASTM D4303), while medical device firms evaluate polymer embrittlement in sterilized packaging (ISO 11607-1). Academic researchers apply it to study photo-oxidative degradation kinetics in biodegradable plastics (ISO 4892-2 Annex A) and pigment stability in cultural heritage conservation science.

FAQ

What spectral filters are included standard with the JH-Series?
Standard configurations include Daylight-Q (full-spectrum) and Window Glass-Q filters. Extended-UV and UV-B-enhanced filters are available as optional accessories.
Can the chamber perform cyclic exposures with condensation phases?
Yes—programmable humidity ramping, spray/no-spray condensation modes, and dark cooling periods are fully supported via WinTest Pro.
Is third-party calibration certification available?
Yes—NIM-traceable irradiance, temperature, and RH calibration reports can be issued prior to shipment or during annual maintenance.
Does the system comply with ASTM G155 Cycle 1–10 protocols?
All JH-Series units are pre-configured to execute ASTM G155 standard cycles; custom cycle development is supported through the software SDK.
What maintenance intervals are recommended for xenon lamps and filters?
Lamp replacement is advised every 1,500–2,000 operating hours; quartz filters require cleaning every 200 hours and replacement every 1,200 hours under continuous operation.
