New-Generation SUNTEST CPS+ Compact Xenon Arc Weathering Test Chamber
BACK
Standards:
The SUNTEST CPS+ complies with numerous international standards: ASTM C1442. C1501. D3424. D5071. D6695. G151. G155 COLIPA in-vitro UVA (2011) EPA/ASTM E896 GB/T 8427. GB/T 16422 ICH Q1B, ICH Q5C ISO 4049. 7491. 10977. 11431. 4892-1. 4892-2. 11979-5. 24443 VICH GL5 L’OREAL QAC-MC-151-O OECD 432. 495
Applications:
The SUNTEST CPS+ is suitable for testing a wide range of materials and industries, including:
Pharmaceuticals and cosmetics – stability and lightfastness studies using SunCool cooling unit
Coatings and sealants – immersion testing with SunFlood device
Plastics, polymers, and packaging materials – color, surface, and physical property changes
Textiles and in-vitro SPF testing – using SunTray accessory
Research laboratories and quality control – accelerated weathering simulations of sunlight, temperature, and moisture effects
Product Information:
The SUNTEST CPS+ Compact Xenon Arc Weathering Test Chamber is a practical tabletop system designed for accelerated light, temperature, and moisture testing. It simulates outdoor or indoor material changes, such as fading, yellowing, or embrittlement, within weeks—changes that would normally take months or years. The chamber accommodates various accessories, enabling customization for different applications, including SunCool for temperature-controlled tests (e.g., pharmaceuticals and cosmetics), SunTray for in-vitro sun protection factor testing, and SunFlood for immersion of coatings or sealants. Its compact design and precise control make it ideal for rapid, reproducible, and reliable short-term weathering studies.

Test Procedures
Mount test specimens on flat or 3D sample holders according to the test method.
Install the required accessory (SunCool, SunFlood, or SunTray) as needed.
Program irradiance, BST, and test duration or select preprogrammed cycles.
Start the test and monitor real-time data on the display panel.
Terminate the test automatically by exposure dose or total test time.
Remove specimens for analysis, including visual inspection, color measurements, or property evaluation.
Maintenance Information
Routine maintenance includes lamp inspection, filter cleaning or replacement, verification of BST sensors, and checking data output interfaces. Ensure the water supply for SunFlood or SunCool units is within recommended specifications. Regular diagnostics provided by the system monitor lamp performance, temperature, and chamber conditions to maintain reproducibility and test accuracy.
FAQ
1. What makes the SUNTEST CPS+ suitable for rapid weathering studies?
The SUNTEST CPS+ simulates months or years of outdoor or indoor exposure within a few weeks by precisely controlling irradiance, temperature, and humidity. Its compact tabletop design, combined with accessory options like SunCool and SunFlood, enables targeted testing for different materials while maintaining reproducibility and reliable results.
2. Can the SUNTEST CPS+ handle 3D samples or only flat specimens?
The chamber accommodates both flat and 3D samples within its 560 cm² horizontal exposure area. Accessories such as SunTray allow for testing curved or irregular specimens, including in-vitro sun protection factor studies, ensuring flexibility across multiple test applications.
3. How is irradiance controlled and monitored in the SUNTEST CPS+?
Irradiance is directly programmed and maintained within the range of 30–65 W/m² for 300–400 nm or 250–765 W/m² for 300–800 nm, using durable coated quartz filters and selective mirrors. BST sensors monitor black standard temperature, ensuring compliance with ISO 4892-1 and providing precise UV exposure for reproducible testing.
