Overview
The IEC 61215 MQT 10 UV Preconditioning Chamber is a walk-in temperature and humidity room designed for accelerated aging and UV+DH testing of PV modules and other large assemblies. Internal dimensions, temperature grades and humidity ranges are customizable to accommodate full-product tests without disassembly.

UV+DH test & materials considerations
Material selection—notably EVA composition and backsheet properties—affects the formation of snail trails and microcracks. UV+DH conditions accelerate moisture-driven defects and can reduce test time versus standard damp-heat cycles. Laser-cut edge conditions and controlled sample designs improve reproducibility for R&D evaluation.

Key Features

• PID temperature and humidity control for stable closed-loop regulation.
• Programmable profiles: 100 patterns × 999 segments with ramp-rate control.
• Real-time humidity sensing and overheat thermostat for independent safety cutoff.
• 50 mm cable test port for in-situ electrical routing to the specimen.
• USB data export for test logs; heated double-glazed observation window with interior lighting.
• External water supply with auto-recycle for humidification; water- or air-cooled refrigeration options.

Standards Supported

• IEC 68-2-1 / 68-2-2 / 68-2-3 / 68-2-30 / 68-2-14
• MIL-STD-810G / MIL-STD-810F
• ISO 16750-3

Applications

• PV module qualification and R&D (UV+DH, damp-heat)
• Electronics, LED and PCB assemblies
• Automotive components and subassemblies
• Household appliances and large equipment reliability testing
• Research laboratories and certification bodies

Deliverables & Service

• Installation & operation manual with wiring diagrams and startup checklist.
• Export packing list and shipping documentation; 12-month warranty covering chamber, refrigeration and controller.
• Standard lead time for custom walk-in builds: 30–40 working days from confirmed drawings.
• Remote technical support and commissioning assistance available.
