Xenon Arc Weathering Test Chamber – OK-XD Series (Imported Lamp, Stainless Steel Construction)

Overview

The OK-XD Series Xenon Arc Weathering Test Chamber is an engineered environmental simulation system designed to replicate full-spectrum solar radiation, temperature, humidity, and moisture cycling under controlled laboratory conditions. Based on ISO 4892-2, ASTM G155, SAE J2527, and IEC 60068-2-9 standards, it employs air-cooled xenon arc lamps emitting a continuous spectrum from 290 nm to 800 nm—closely matching terrestrial sunlight—including critical UV-B and visible bands. The chamber integrates precise black panel temperature control (55–90°C ±3°C), programmable relative humidity (50–98% RH), and synchronized water spray cycles to accelerate material degradation mechanisms such as photooxidation, chalking, color fading, gloss loss, and polymer chain scission. Its robust stainless steel construction (SUS304 interior, A3 steel exterior with epoxy coating), multi-layer insulated cavity, and non-metallic high/low-temperature seals ensure long-term thermal stability and operational integrity across repeated thermal-hygric stress cycles.

Key Features

• Triple 1.8 kW air-cooled xenon lamps delivering calibrated irradiance up to 550 W/m² (290–800 nm), with spectral filtering options available for UV-cut or daylight simulation;
• 360° continuously rotating sample rack (standard 350 × 350 mm tray) ensuring uniform exposure and eliminating positional bias;
• High-precision black panel temperature sensor (metal type) mounted adjacent to test specimens for direct surface thermal monitoring;
• Programmable rain cycle system: adjustable spray duration (1–9999 min), interval timing (1–240 min), and fixed spray/no-spray ratio (e.g., 18/102 min) compliant with ASTM D2244 and ISO 11341;
• Multi-layer tempered glass observation window with anti-fog heating element enabling real-time visual assessment without interrupting test conditions;
• Full insulation using ultra-fine glass fiber and non-metallic thermal break interfaces, minimizing heat leakage and improving energy efficiency;
• Four-caster mobility system with locking mechanism for safe repositioning within lab environments;
• Compliant power architecture: 3-phase 5-wire 380 V ±10% / 50 Hz, including dedicated grounding and surge protection per IEC 61000-4-5.

Sample Compatibility & Compliance

The OK-XD chamber accommodates flat, rigid, or semi-flexible specimens—including automotive coatings, architectural sealants, textile fibers, plastic housings, and aerospace composites—up to 800 mm × 1000 mm × 1000 mm (OK-XD-800 model). All internal surfaces meet ISO 17025-compliant cleanliness requirements for traceable testing. The system supports standard specimen mounting per ASTM D6675 (textiles), ISO 11341 (paints), and GB/T 16422.2 (China national standard). Calibration certificates for irradiance, temperature, and humidity sensors are traceable to NIST or equivalent national metrology institutes. Full compliance documentation—including design qualification (DQ), installation qualification (IQ), and operational qualification (OQ)—is provided upon request for GLP/GMP-regulated laboratories.

Software & Data Management

Controlled via a 7-inch industrial-grade touchscreen HMI with embedded real-time logging, the OK-XD platform records irradiance (W/m²), black panel temperature (°C), chamber humidity (%RH), spray status, and elapsed time at user-defined intervals (1 s to 60 min). Data exports in CSV format support post-test analysis in MATLAB, Excel, or LIMS platforms. Optional PC-based software enables remote monitoring, multi-chamber synchronization, alarm escalation (email/SMS), and audit trail generation compliant with FDA 21 CFR Part 11 requirements—including electronic signatures, user access levels, and immutable event logs. All firmware updates undergo version-controlled validation per ISO/IEC 17025 Clause 5.9.2.

Applications

• Accelerated weathering validation of OEM automotive exterior components (bumpers, grilles, trim) per SAE J2412 and GMW14124;
• UV resistance certification of architectural PVC profiles, silicone sealants, and roofing membranes per ASTM D4329 and EN 1297;
• Colorfastness and gloss retention testing for textile dyes and printed fabrics per ISO 105-B02;
• Photostability screening of pharmaceutical packaging materials (HDPE, PET, aluminum laminates) per ICH Q1B guidance;
• Long-term durability assessment of photovoltaic module encapsulants and backsheets per IEC 61215-2 MQT10;
• Research-grade degradation kinetics modeling in polymer science labs requiring reproducible radiant exposure dosimetry.

FAQ

What is the typical service life of the xenon lamps?
Lamps are rated for 1600–1800 hours of continuous operation under nominal irradiance settings. Actual lifespan depends on operating intensity, cooling efficiency, and voltage stability.
Can the chamber operate without water spray functionality?
Yes—the rain system is fully independent and can be disabled while maintaining irradiance, temperature, and humidity control.
Is calibration verification included with delivery?
A factory calibration report covering irradiance uniformity, temperature/humidity accuracy, and black panel response is supplied. On-site calibration services are available upon request.
Does the system meet FDA 21 CFR Part 11 requirements?
The optional PC software package includes full electronic signature capability, audit trails, and role-based access control—validated for regulated environments.
What maintenance is required for long-term reliability?
Recommended quarterly tasks include lamp alignment verification, filter cleaning, humidity sensor recalibration, and inspection of spray nozzles (Ø0.8 mm) for clogging.
