Atlas Ci5000 Xenon Arc Weathering Test Chamber

Overview

The Atlas Ci5000 Xenon Arc Weathering Test Chamber is an advanced, digitally controlled laboratory instrument engineered for accelerated weathering simulation under precisely regulated spectral irradiance, temperature, and humidity conditions. Based on xenon arc lamp technology—widely recognized as the most spectrally accurate artificial light source for replicating full-spectrum solar radiation—the Ci5000 enables reproducible evaluation of material degradation mechanisms including photooxidation, chalking, cracking, color fading, gloss loss, and polymer chain scission. Its optical architecture incorporates water-cooled 12,000 W xenon lamps with interchangeable filter systems that emulate terrestrial sunlight across critical UV, visible, and near-infrared bands. Designed for compliance-driven industries such as automotive OEMs, aerospace coatings suppliers, architectural finish manufacturers, and polymer compounders, the Ci5000 delivers traceable, audit-ready test data aligned with international exposure protocols.

• Front- and rear-mounted spray systems enabling cyclic wet/dry exposure per ISO 11341, ASTM D4329, and SAE J2527
• Smart Damper™ dynamic compensation system minimizes thermal and hygric drift caused by ambient lab fluctuations, ensuring long-term test stability
• Integrated USB storage and Ethernet connectivity for secure, timestamped data export compliant with GLP/GMP documentation practices
• Universal electrical configuration supporting 100–240 VAC, 50/60 Hz operation with built-in surge suppression and harmonic filtering

Sample Compatibility & Compliance

The Ci5000 accommodates diverse specimen geometries—including flat panels, molded parts, textiles, composites, and coated substrates—via adjustable sample holders and universal clamping fixtures. Its mechanical and environmental control architecture satisfies functional requirements of key international standards: ISO 4892-2 (xenon arc exposure), ISO 11341 (rubber/weathering), ASTM G155 (non-metallic materials), ASTM D4329 (plastics), SAE J2527 (automotive interior), AATCC TM16 (textiles), and GB/T 16422.2 (Chinese national standard). All safety-critical subsystems—including lamp enclosure interlocks, overtemperature cutoffs, and emergency ventilation—conform to CE, UL 508A, CSA C22.2 No. 14, and EN 61000 electromagnetic compatibility directives. The system supports 21 CFR Part 11-compliant audit trails when paired with validated LIMS or ELN platforms.

Software & Data Management

Control firmware includes embedded logging of all operational parameters at 1-second resolution, with automatic generation of CSV-formatted reports containing irradiance history, temperature/humidity profiles, lamp runtime, and fault codes. Data export via Ethernet enables direct integration into enterprise quality management systems (QMS) or statistical process control (SPC) dashboards. The onboard USB port supports encrypted data transfer and firmware updates; a pre-installed USB drive ensures immediate archival without external media dependency. Twelve programmable test slots allow storage of complex multi-phase cycles—including irradiance ramps, humidity step changes, and spray sequencing—with sub-cycle granularity for method validation studies. All user actions are timestamped and logged for regulatory review.

Applications

The Ci5000 serves as a primary qualification tool in R&D laboratories and QC departments where predictive durability assessment is mission-critical. Typical use cases include: accelerated aging of automotive exterior trim and headlamp lenses per SAE J2412; UV resistance validation of architectural sealants and elastomeric coatings per ASTM C1135; colorfastness testing of automotive interior fabrics per ISO 105-B02; weatherability screening of photovoltaic encapsulants per IEC 61215; and outdoor stability benchmarking of biodegradable polymers per ISO 14855. Its reproducibility profile supports Design of Experiments (DoE) workflows, failure mode analysis, and correlation studies against field exposure data from Atlas’ global network of outdoor test sites.

FAQ

What irradiance sensors are supported by the Ci5000?
The system accepts calibrated broadband (300–400 nm), narrowband (340 nm), and visible (lux) irradiance sensors certified to NIST-traceable standards.
Can the Ci5000 operate without continuous operator supervision?
Yes—fully autonomous operation is enabled via scheduled start/stop, email alerts for anomalies, and unattended 24/7 cycling with integrated lamp life monitoring.
Is the water spray system compatible with deionized water only?
While DI water is recommended to prevent nozzle scaling, the system includes conductivity-based water quality sensing and automatic shutdown if TDS exceeds configurable thresholds.
How does Smart Damper™ improve test repeatability?
It dynamically adjusts internal airflow and heater/cooler duty cycles in response to real-time lab ambient shifts, reducing chamber parameter deviation by up to 40% versus conventional designs.
Are filter sets included with the base configuration?
Standard delivery includes Daylight-Q/B, Window Glass-Q/B, and Extended UV-Q/B filter combinations; additional filters are available as optional accessories.
