The SUNTEST XLS+ complies with numerous international standards: adidas FT-11 ASTM C1442. C1501. D3424. D5071. D6695. G151. G155 EPA/ASTM E896 GB/T 8427. GB/T 16422 ICH Q1B, ICH Q5C ISO 4892-1. ISO 4892-2. ISO 10977. ISO 11431. ISO 16474-2. ISO 11979-5 OECD 316. OECD Guideline UATM M15 VICH GL5
Applications:
The SUNTEST XLS+ is suitable for testing diverse materials and industries, including:
Polymers and coatings – accelerated UV and weathering tests
3D products – dimensional or structural samples exposed using the horizontal test area
Pharmaceuticals and beverages – temperature-controlled tests using SunCool accessory
Coatings, sealants, and packaging materials – immersion and spray tests using SunFlood or SunSpray
Research laboratories and quality control – simulation of sunlight, temperature, and moisture exposure to predict short-term material performance
Product Information:
The SUNTEST XLS+ Compact Xenon Arc Weathering Test Chamber is a modern tabletop system designed for accelerated light, temperature, and moisture testing of both flat and 3D samples. It simulates months or years of outdoor or indoor exposure—including fading, yellowing, or strength loss—within just a few weeks. Equipped with versatile and user-friendly accessories, SUNTEST XLS+ adapts to different testing needs, providing highly reproducible and precise short-term weathering studies across a wide range of materials.

FAQ
1. What makes SUNTEST XLS+ ideal for 3D sample testing?
The SUNTEST XLS+ features a 1170 cm² horizontal exposure area that accommodates multiple flat or 3D samples. Combined with accessories like SunFlood or SunSpray, it provides uniform irradiance, precise temperature control, and realistic daylight simulation for complex geometries, ensuring reproducible and accurate accelerated weathering results.
2. How is irradiance controlled and monitored?
Irradiance is directly programmable and maintained within ranges of 30–65 W/m² (300–400 nm), 0.26–0.62 W/m² (340 nm), 250–765 W/m² (300–800 nm), or 45–130 klx (Lux). Black Standard Temperature (BST) sensors monitor and maintain sample surface conditions in compliance with ISO 4892-1. ensuring repeatable test results.
3. Can the SUNTEST XLS+ simulate both sunlight and artificial light conditions?
Yes. Optional filter sets allow simulation of sunlight or indoor artificial light. Coupled with precise irradiance and temperature control, this feature ensures realistic testing conditions for a wide range of applications, including polymers, coatings, and cosmetic formulations.
