SUGA GX75 7.5kW Xenon Weather Meter
Applicable Standards
The GX75 meets stringent international standards, including:
- ISO 4892-2,ASTM G155,SAE J2527(automotive coatings)
- JIS K7350-2(Japan Industrial Standard for weathering tests)
- AATCC TM16,GB/T 16422.2(China’s national standard for xenon-arc exposure)
These standards ensure reliable evaluation of material durability, colorfastness, and aging resistance.
Working Principle
The GX75 uses a xenon arc lamp to emit a spectrum closely matching natural sunlight, including UV, visible, and infrared radiation. A water-cooling system maintains lamp stability, while advanced filters adjust spectral distribution. The tester controls irradiance, temperature, humidity, and spray cycles via a touchscreen controller, enabling precise replication of diverse environmental conditions.
Test Principle
Materials undergo accelerated aging through cyclic exposure to light, heat, moisture, and rain. The GX75 simulates years of outdoor exposure in weeks by:
- Photo-oxidation: UV radiation breaks chemical bonds, causing fading, cracking, or embrittlement.
- Thermal Stress: High temperatures accelerate degradation mechanisms.
- Humidity/Rain: Moisture exacerbates hydrolysis and corrosion.
- Dark Cycles: Alternating light/dark cycles mimic nighttime condensation.
By adjusting parameters, the GX75 predicts material lifespans, aiding in R&D and quality control.
The SUGA GX75 is a cornerstone for accelerated weathering testing, offering unmatched precision, efficiency, and compliance with global standards.
