Jianhu XW-6500 Xenon Arc Weathering Test Chamber

Overview

The Jianhu XW-6500 Xenon Arc Weathering Test Chamber is an ISO 4892-2 and ASTM G155-compliant environmental test system engineered for accelerated weathering evaluation of polymeric materials, elastomeric seals, coatings, and composite components under controlled solar-spectrum irradiation. Utilizing a water-cooled or air-cooled xenon arc lamp with full-spectrum output (290–2500 nm), the chamber replicates critical outdoor degradation drivers—including UV radiation, thermal cycling, humidity, and optional rain simulation—enabling laboratory-based assessment of long-term durability in accordance with international standards for automotive, aerospace, and energy applications. Its architecture integrates real-time spectral monitoring, closed-loop irradiance feedback control, and independent temperature/humidity regulation to ensure high reproducibility across test cycles. Designed specifically for QC laboratories, R&D centers, and third-party testing institutes, the XW-6500 supports GLP-compliant data integrity through audit-trail-enabled software and meets foundational requirements for FDA 21 CFR Part 11 readiness when deployed with validated configurations.

Key Features

• High-fidelity xenon arc source with quartz envelope and IR-cut filter assemblies, delivering spectral power distribution closely aligned with CIE No. 85 global solar reference spectrum (AM 1.5)
• Dual-mode irradiance control: broadband (300–800 nm) or narrowband (e.g., 340 nm or 420 nm) monitoring with calibrated silicon photodiode sensors and automatic lamp power compensation
• Precise black-panel temperature control (40–110°C) and chamber air temperature regulation (10–80°C), both independently adjustable via PID algorithms
• Humidity control system with steam generator and condensation-resistant stainless-steel humidification chamber; maintains 20–98% RH with ±2% RH tolerance over full operating range
• Optional spray function with deionized water delivery, programmable spray-on/spray-off intervals, and adjustable nozzle pressure (0.1–0.3 MPa) for simulated rainfall erosion testing
• Robust stainless-steel interior (SUS304), double-wall insulation, and forced-air convection for uniform thermal distribution and minimal gradient deviation (< ±1.5°C)
• Compliance-ready design: pre-configured I/O interfaces for external gas dosing (O₂, SO₂, NOₓ), optional corrosion gas module integration, and ventilation exhaust port for hazardous fume management

Sample Compatibility & Compliance

The XW-6500 accommodates flat-panel specimens up to 600 mm × 600 mm × 50 mm (W×D×H), with rotating sample racks (optional) ensuring uniform exposure. It supports standardized specimen holders per ISO 4892-2, ASTM D4329, SAE J2527, and GB/T 16422.2. All operational parameters—including irradiance, temperature, humidity, and cycle sequencing—are traceable to NIST-calibrated references. The system satisfies essential clauses of ISO/IEC 17025 for accredited testing laboratories and aligns with functional requirements of IEC 61215 (photovoltaic modules), UL 746C (polymeric materials), and USP (package integrity). Optional calibration kits include spectral radiometers and reference film dosimeters for in-house verification of UV dose accumulation.

Software & Data Management

Equipped with Jianhu’s WinTest Pro v4.2 control software, the XW-6500 provides multi-user role-based access, real-time parameter trending, and automated report generation in PDF/CSV formats. All setpoints, sensor readings, alarm events, and manual interventions are time-stamped and stored with cryptographic hashing to prevent tampering—fulfilling core audit-trail requirements under GLP and GMP frameworks. Data export supports LIMS integration via OPC UA and Modbus TCP protocols. Software validation documentation (IQ/OQ/PQ templates) is provided upon request, and the system supports electronic signatures compliant with 21 CFR Part 11 when deployed on domain-joined Windows servers with Active Directory authentication.

Applications

The XW-6500 is routinely deployed for accelerated aging studies of battery pack gaskets and sealing systems in electric vehicle development programs, where material performance under combined UV/thermal/hygrometric stress directly informs IP67/IP6K9K certification pathways. It is also used for evaluating UV stability of aerospace elastomers (per AMS 2772), weather resistance of architectural sealants (ASTM C719), lightfastness of medical device packaging (ISO 11607-1), and photochemical degradation kinetics of polymer electrolytes in solid-state batteries. Its flexibility in simulating multi-stress environments makes it suitable for failure mode analysis, comparative material screening, and regulatory submission dossiers requiring reproducible environmental stress data.

FAQ

What spectral range does the xenon lamp cover, and how is it filtered?

The lamp emits continuous radiation from 290 nm to 2500 nm; standard configurations include Daylight-Q filter (matching terrestrial solar UV/visible/NIR) and Window Glass-Q filter (simulating indoor透过 glass exposure). Filters are certified per ISO 4892-2 Annex A.

Can the chamber operate under continuous dark cycles?

Yes—dark periods are fully programmable and may include controlled temperature/humidity conditions without irradiation, enabling simulation of nocturnal thermal contraction or dew formation.

Is ozone generation mitigated during operation?

Integrated catalytic ozone destruct units and active exhaust ventilation maintain ozone concentrations below 0.1 ppm at operator breathing zone, per OSHA PEL guidelines.

How is irradiance uniformity verified across the test area?

Uniformity is validated using a 5-point grid mapping protocol per ASTM G155 Section 7.3; typical deviation is ≤±5% across the central 75% of the exposure plane.

Does the system support remote monitoring and alarm notification?

Yes—Ethernet-connected units support SNMP traps, email/SMS alerts for critical faults (e.g., lamp failure, humidity deviation >5% RH), and secure web-based dashboard access via TLS 1.2 encryption.
