MIL, ASTM, CNS, IEC, JIS, AATCC, DIN, Fed Test, BS, SAE, ASTM D4355
ISO-4892, ASTM-G53, D4587, 4799, BS-27282, SAE-J2020
Primary Functions
The QUV UV test machine utilizes UV lamps to simulate sunlight
effects, while condensation and water spray systems replicate rain
and dew conditions. Temperature is precisely controlled throughout
testing cycles. Typical testing involves UV radiation at high
temperatures followed by 100% humidity in dark conditions. Commonly
used for paint, coatings, automotive components, plastic products,
wood products, and adhesives.

Equipment Overview
The QUV UV aging testing machine simulates sunlight, rain, and dew
to accelerate material degradation. Materials are exposed to
alternating light and moisture cycles. Testing for days or weeks
replicates months or years of outdoor exposure. Damage assessment
includes: bleaching, discoloration, gloss loss, powdering,
cracking, turbidity, bubbling, embrittlement, strength reduction,
and oxidation.

Key Features
Sunlight Simulation
Material durability damage primarily results from solar ultraviolet
radiation. UV lamps simulate short-wave ultraviolet spectrum with
minimal visible or infrared energy. Different UV lamp types
available for specific testing requirements.
UV Lamp Types
UVA-340: Excellent simulation of short-wave UV sunlight from 365nm to 295nm
cutoff wavelength.
UVB-313: Provides stronger short-wave UV radiation than terrestrial
sunlight for accelerated aging, ideal for quality control and
R&D.
UVA-351: Simulates UV sunlight through windows, effective for indoor
material aging tests.
Moisture Condensation Environment
Simulates outdoor dew conditions (up to 12 hours daily). Unique
condensation system uses heated water reservoir to generate steam,
maintaining 100% relative humidity. Sample temperature
differentials create continuous condensation cycles.
Precise Temperature Control
Accurate temperature regulation throughout testing cycles
accelerates aging while ensuring test reproducibility. Temperature
monitoring via board thermometer.
Water Spray System
12-nozzle system (6 per side) simulates rainfall and thermal shock
conditions. Short spray cycles create rapid cooling for thermal
shock simulation and mechanical erosion testing.
Irradiation Intensity Control
Optional light intensity control system enables precise,
reproducible results. Feedback loop device extends fluorescent lamp
life while maintaining consistent radiation levels.
