Overview
The Jianhu XQ-6500 Xenon Arc Weathering Test Chamber is an ISO/ASTM-compliant environmental simulation system engineered for accredited testing laboratories requiring high-fidelity replication of full-spectrum solar irradiation. It employs water-cooled or air-cooled xenon arc lamps with precision-filtered optics to deliver a spectral power distribution closely matching terrestrial sunlight (CIE 85:1989, ISO 4892-2:2013), including critical UV-B (280–315 nm), UV-A (315–400 nm), visible (400–700 nm), and near-infrared (700–800 nm) bands. Unlike UV fluorescent or metal halide sources, xenon arc technology enables simultaneous acceleration of photochemical degradation, thermal aging, and moisture-induced failure mechanisms—essential for evaluating long-term durability of polymeric encapsulants (e.g., EVA, POE), coatings, textiles, automotive interiors, and aerospace composites under controlled, repeatable conditions.
Key Features
- Triple-parameter environmental control: independent regulation of irradiance (0.35–1.20 W/m² @ 340 nm, traceable to NIST-calibrated radiometers), black-panel temperature (BST: 40–110°C), and chamber-relative humidity (20–98% RH, ±2% RH uncertainty)
- Programmable exposure cycles supporting multi-stage protocols per ASTM G155-18 and GB/T 16422.2-2014—including light-only, light+dark, light+spray, and humidity-condensation phases
- Real-time irradiance feedback loop with closed-loop servo control, ensuring ±3% irradiance stability over 1,000-hour test durations
- Full-spectrum quartz filter system (Daylight-Q/B, Window Glass-Q/B) enabling compliance with both outdoor and automotive glazing exposure requirements
- Integrated spray system with deionized water delivery, adjustable frequency/duration, and nozzle corrosion resistance (316L stainless steel)
- Robust chamber construction: SUS304 stainless steel interior, double-wall insulation, and forced-air convection for uniform thermal distribution (±1.5°C spatial uniformity at 65°C)
Sample Compatibility & Compliance
The XQ-6500 accommodates flat-panel specimens up to 600 mm × 400 mm × 50 mm (W×H×D) on motorized, rotating sample racks—ensuring angular uniformity of irradiance exposure across all samples. It supports standardized specimen mounting per ISO 4892-2 Annex A and ASTM G155 Figure 1, with optional fixtures for rigid substrates, flexible films, and 3D components. The chamber meets essential regulatory frameworks for laboratory accreditation: ISO/IEC 17025:2017 (clause 6.4.3 on equipment verification), IEC 61215-2:2016 (photovoltaic module qualification), and UL 746C (polymeric materials). All irradiance calibration reports are issued with measurement uncertainty budgets compliant with ILAC-G8:2009, and humidity sensors are certified to ISO 17025-accredited calibration labs.
Software & Data Management
Equipped with Jianhu’s proprietary WinTest Pro v4.2 software, the XQ-6500 provides audit-trail-capable operation under FDA 21 CFR Part 11 and EU Annex 11 requirements. Software features include: user-level access control (admin/operator/viewer roles), electronic signature logging, automatic generation of IQ/OQ/PQ documentation templates, real-time graphing of irradiance, BST, RH, and chamber ambient temperature, and export of time-stamped CSV/Excel datasets with metadata (test ID, operator, calibration date, lamp hours). Data integrity is enforced via SHA-256 hashing of raw logs and write-once-read-many (WORM) storage options. Remote monitoring via Ethernet/IP is supported, with TLS 1.2 encryption for secure data transmission.
Applications
The XQ-6500 serves as a primary tool in third-party certification laboratories for accelerated weathering validation across regulated industries. In photovoltaics, it executes IEC 61215-2 MQT10 (UV pre-conditioning), IEC 62788-7-2 (EVA encapsulant yellowing index), and UL 1703 Annex D (backsheet durability). For automotive suppliers, it satisfies SAE J2527 (exterior materials) and ISO 20699 (interior trim). In packaging, it supports ASTM D7209 (plastic film UV resistance) and ISO 11664-3 (colorfastness). Its traceable irradiance control and GLP-aligned operation make it suitable for submissions to notified bodies (e.g., TÜV Rheinland, UL, Intertek) and regulatory filings requiring documented reproducibility (e.g., FDA 510(k), CE marking technical files).
FAQ
What standards does the XQ-6500 comply with for photovoltaic testing?
It fully supports IEC 61215-2:2016 (MQT10, MQT11), IEC 62788-7-2:2021, and UL 1703:2022 Annex D, with spectral match Class A per ISO 4892-2:2013.
Can the chamber operate without spray functionality?
Yes—spray mode is fully programmable and may be disabled or scheduled independently of light/dark cycles.
How is irradiance calibrated and maintained over lamp lifetime?
Each lamp is paired with a NIST-traceable broadband radiometer; automated recalibration occurs every 200 lamp-hours, with lamp replacement alerts triggered at 1,500 hours or when irradiance drift exceeds ±5%.
Is humidity control validated across the full 20–98% RH range?
Yes—humidity uniformity and accuracy are verified per ISO 17025 using chilled-mirror hygrometers at five spatial locations, with certificates provided upon installation and annually.
Does the system support remote diagnostics and firmware updates?
Yes—secure remote access via HTTPS-based web interface allows real-time status monitoring, alarm history review, and over-the-air firmware upgrades signed with ECDSA-256 cryptographic signatures.
