The SUGA GX25 Xenon Lamp Weathering Tester is a compact yet powerful environmental simulation instrument specifically engineered to evaluate the lightfastness and weather resistance of daily commodities, packaging, and high-tech components. By utilizing a 2.5kW water-cooled xenon arc lamp, this tester provides a stable and accurate reproduction of the solar spectrum, allowing you to observe the degradation of materials caused by sunlight, heat, and humidity. It is an essential tool for manufacturers looking to predict product lifespan and maintain color stability in diverse consumer and industrial markets.
Applications
Traditional Automotive: Brakes, steering wheels, manual transmissions, interior components, airbags, child safety seats
LCD: Materials (backlighting, color filters, glass substrates, liquid crystal materials, polarizers, driver assemblies), application products (TVs, monitors, computers, tablets, smarts, wearables, etc.)
Electrical & Electronics: Home appliances, office equipment
Pharmaceuticals: Medicinal products
Food: Beverage production
Standards
ISO 4892-2: Plastics—Methods of exposure to laboratory light sources (Xenon-arc lamps).
ISO 105-B02: Textiles—Tests for color fastness to artificial light (Xenon arc fading lamp test).
ASTM G155: Standard Practice for Operating Xenon Arc Light Apparatus for Exposure of Nonmetallic Materials.
AATCC TM16.3: Colorfastness to Light: Xenon-Arc.
JIS L0843: Test method for color fastness to xenon arc lamp light.
JIS K7350-2: Plastics—Methods of exposure to laboratory light sources—Part 2: Xenon-arc lamps.
Features
Stable Water-Cooled Source: The 2.5kW water-cooled system manages the thermal load of the xenon lamp more efficiently than air-cooled alternatives, providing superior spectral stability and longer lamp life.
High-Temperature Capability: You can achieve a Black Panel Temperature (BPT) of up to $110^{circ}text{C}$, allowing for the simulation of extreme heat conditions found in automotive interiors or tropical outdoor environments.
Large Throughput for Compact Size: Despite its manageable footprint, the GX25 can accommodate up to 108 specimens simultaneously, making it ideal for high-volume batch testing.
Precise Dark Cycle Simulation: The system allows you to transition to a high-humidity dark mode ($95%text{ RH}$), effectively simulating nighttime dew and moisture absorption.
Customizable Spectrum: By utilizing specific filter combinations like the #295 outer filter, you can tailor the UV cutoff to match specific outdoor or indoor sunlight conditions.

Accessories
Xenon Burner: Replacement 2.5kW water-cooled xenon arc lamp.
Filter Sets: Various inner and outer filters (e.g., #295. #320. Quartz) for spectral adjustment.
Specimen Holders: Stainless steel clips designed for standard $65 times 55text{ mm}$ samples.
Black Panel Thermometer (BPT): Integrated sensor for accurate surface temperature monitoring.
Cooling Water Unit: Deionizer and heat exchanger system for lamp cooling.
Test Procedures
1. Sample Mounting
Secure your specimens into the stainless steel holders. Ensure the surface of the material is flush with the holder frame to guarantee uniform irradiance across the sample face.
2. Loading the Chamber
Place the holders onto the rotating specimen rack. Distribute them evenly to maintain the mechanical balance of the drum and ensure consistent airflow during the test.
3. Program Setting
Input your test parameters via the control panel. Define the irradiance level (e.g., $42text{ W/m}^2$), the BPT for the light cycle, and the duration for both irradiation and dark phases.
4. Initiating Operation
Confirm that the cooling water is flowing and the filters are clean. Start the test. The specimen drum will rotate around the central xenon lamp, providing equal exposure to all 108 samples.
5. Assessment
Once the pre-set exposure time or radiant dose is reached, the system will automatically shut down. Remove the samples and compare them against a control specimen or a standard gray scale to evaluate color change.
