The SUNTEST XLS+ is a benchtop solar weathering tester suitable for 3D specimens, simulating material degradation caused by sunlight, temperature, and moisture in a short period of time. It features advanced solar radiation simulation, a multi-language touchscreen interface, automatic irradiance control, and a wide range of accessories to meet diverse testing needs. The instrument has an exposure area of 1,170 square centimeters, supports multi-stage test programming, and is compatible with ISO 4892-1.
Aging is the adverse reaction of a material or product to climate change, often leading to undesirable premature product failure. The primary factors contributing to aging are sunlight, temperature, and humidity. Sunlight induces and exacerbates degradation, and it interacts with temperature and humidity to negatively impact materials or products. The purpose of artificial aging is to replicate the degradation process and its resulting damage under simulated laboratory conditions at an accelerated pace. Since 1976, the SUNTEST has been a widely used test chamber for accelerated materials testing. Material changes caused by light, temperature and humidity, such as fading, embrittlement and yellowing, which would take months or even years to occur in the end-use environment, can be achieved in days or weeks through SUNTEST's simulation of real-world conditions.
Advantages of SUNTEST XLS
Accurate and Reproducible Test Results
Accelerated weathering equipment requires not only a high-quality test chamber but also advanced light sources, sophisticated sensors, and intelligent control systems. Precise calibration ensures perfect interaction between each component, ensuring high-quality testing conditions and reproducible test results.
Sunlight Simulation
ATLAS xenon lamps provide uniform irradiance and stable spectral energy output. Their spectral output closely resembles sunlight. The significant advantage of simulating the full sunlight spectrum is that, because visible and infrared light correlate with specimen color, it faithfully reproduces the specimen's natural heating conditions. ATLAS offers a range of filters that comply with ISO 4892-2 and ASTM G155 standards, including daylight and window glass filters. We can also custom-manufacture specialized filters to meet specific customer requirements (see the "Optional Accessories" section).
High-Quality Lamps
All ATLAS weathering testers utilize specially designed, professional sunlight-simulating xenon lamps. The xenon lamp provides optimal spectral energy output throughout its lifetime. We offer complete "plug-and-play" lamp cartridges, greatly facilitating lamp and filter replacement.
Temperature Control
Temperature plays a significant role in material degradation rates. The most relevant temperature parameter for weathering tests is the black standard temperature. All SUNTEST instruments can measure and control the maximum surface temperature of black specimens according to ISO 4892-1.
Humidity Control
The third most significant factor affecting weathering is humidity, which includes moisture, condensation, and rainfall. The SUNTEST XLS+ is available with optional specimen spraying and immersion functions, while the CPS+ model also offers an optional immersion device. The SUNTEST XXL+ uses an ultrasonic humidification system to control relative humidity, providing extremely uniform water vapor distribution. The built-in 60-liter water tank ensures uninterrupted operation, providing water for multiple days without refilling.
Advanced Benchtop Xenon Arc Weathering Tester
The SUNTEST XLS+ is a modern benchtop xenon arc weatherometer designed as a best-in-class solution for testing 3D specimens. This sophisticated weathering tester allows you to examine material and product performance changes caused by sunlight, temperature, and humidity in significantly shorter timeframes. Weathering processes that typically occur outdoors or indoors over months or years, such as fading, yellowing, or strength loss, can typically be simulated in weeks with the SUNTEST XLS+.
This advanced instrument features advanced simulation of solar radiation according to the CIE85 reference sun standard, simulating sunlight filtered through window glass and artificial supermarket lighting conditions. Utilizing state-of-the-art UV control technology, the SUNTEST XLS+ is designed for reliable R&D testing of new materials and standardized quality control applications in a variety of end-use environments.
User-Friendly Design and Operation
The SUNTEST XLS+ features an intuitive touchscreen user interface available in 13 selectable languages, enabling global operator adoption. The system comes with pre-programmed standards for quick start-up, allowing immediate testing according to established protocols. The benchtop design, measuring 90 x 54 x 62 cm, fits comfortably in any laboratory environment while offering a maximum exposure area of 1100 cm² to accommodate both flat and 3D samples.
The instrument features a microprocessor-based controller for precise measurement and adjustment, working in conjunction with software-controlled test programs. Irradiance can be directly set and controlled within the 300-400 nm (including 340 nm) or 300-800 nm wavelength ranges, and irradiance can be automatically controlled to meet diverse testing needs. Temperature control utilizes a Black Standard Temperature (BST) sensor compliant with ISO 4892-1.
Versatile Testing Capabilities
The SUNTEST XLS+ provides comprehensive weathering simulation with controlled irradiance ranges of 30-65 W/m² (300-400 nm), 0.26-0.62 W/m² (340 nm), or 250-765 W/m² (300-800 nm), and an illuminance capability of 45-130 klx. Temperature control from 45-100°C using a Black Standard temperature system ensures precise environmental simulation for accurate test results.
Optional accessories further expand testing capabilities, including the SunSpray unit for water spraying during weathering tests, the SunFlood immersion unit for testing in extreme humidity conditions, and the SunCool cooler for low-temperature testing applications such as pharmaceuticals and beverages. These accessories allow users to customize the SUNTEST XLS+ to meet the specific testing requirements of different applications.
Reliable Flatbed Accelerated Xenon Lamp Exposure System
The SUNTEST series of flatbed xenon arc weathering instruments are easy to use and are ideal for screening new materials in various environments, standard quality control testing (materials and components), and pharmaceutical R&D testing. Consistently ensuring repeatable and reproducible test results is a hallmark of ATLAS instruments, and the SUNTEST series stands for this same commitment. Using a filtered xenon lamp, each SUNTEST instrument provides consistent irradiance and accurately simulates sunlight. Tests have shown that ATLAS xenon lamps provide more consistent and stable sunlight simulation than other xenon lamps, and their performance is unaffected by lamp life.
Equipment to Perfectly Meet Your Testing Needs
The SUNTEST series of instruments comes in three different sizes to perfectly meet your testing needs. The two benchtop models, the CPS+ and XLS+, offer controlled light and temperature, making them ideal for weathering tests on small specimens. The large, vertical XXL+ tester features comprehensive automated lighting, temperature, and humidity control, meeting all international weathering testing standards.
Applications of The SUNTEST XLS
SUNTEST equipment is suitable for a wide range of applications across multiple industries. Flatbed testing technology allows for testing specimens of various shapes and sizes. Optional accessories for cooling specimens are particularly useful for light stability testing of heat-sensitive products, such as pharmaceuticals or cosmetics. A range of accessories and optical filter systems enable the tester to meet specific industry standards (ICH, COLIPA) or simulate specialized environments, such as outdoor, indoor, warehouse, or store lighting (see the Optical Filters section).
