Testing Powered Electronics.

Instrument configuration enables testing of powered electronics during Xenon Arc Exposure.

Atlas Material Testing Technology has introduced the Ci5000E Weather-Ometer®, a new configuration of its Ci5000 xenon arc platform designed specifically for accelerated testing of powered electronic devices and components. Developed to meet the evolving accelerated weathering requirements of the electronics industry, the Ci5000E allows manufacturers to keep electronic specimens powered and operating during controlled xenon arc exposure.

Operating electronic components generate their own heat, carry electrical loads and perform active functions that are not present when the components are evaluated while they are unpowered. Powered testing can help manufacturers evaluate how displays, sensors and other electronic functions respond to light and heat while under operational load.

“The challenge was not simply getting power into the test chamber," said Chelsea Todd, Product Marketing Manager at Atlas. "It was doing so while maintaining the proven exposure performance, uniformity and repeatability of the Ci5000 platform.”

The Ci5000E incorporates several design features that make powered testing possible while maintaining controlled exposure conditions:

• Cable-access porthole for routing power and signal connections into the test chamber
• Slip-ring-enabled power delivery through the specimen rack while it remains in motion during testing
• Oscillating specimen rack that replaces the platform's continuous rotation, supporting irradiance and temperature uniformity while allowing power and signal cables to be routed and managed without winding
• Air-baffle design that supports consistent chamber airflow and exposure conditions

Built on the Ci5000 platform widely used for accelerated xenon arc testing in automotive and other demanding applications, the Ci5000E delivers the same controlled light and temperature conditions while adding the ability to power and operate electronic specimens during exposure. It retains the largest test chamber in the Weather-Ometer family, providing room for powered specimens and their associated cabling and connections. The Ci5000E configuration does not include the Ci5000 specimen-spray option.

Accelerated weathering testing.

Atlas has introduced the next generation Xenotest® 220 and 440 xenon-arc instruments featuring expanded test method support, and improved integration with lab networks. Designed for demanding applications in the polymer, coatings, automotive and textile industries, the upgrades simplify operation while enhancing test consistency and day-to-day reliability.

The air-cooled, rotating-rack Xenotest 220 and 440 simulate the effects of sunlight, heat, and moisture to accelerate material testing under controlled conditions. Their high sample capacity in a compact footprint, and robust performance make them a trusted platform for lightfastness and weathering evaluations.

Expanded standards and method support.
The range of preloaded test protocols has been significantly extended and now covers all commonly used ASTM, AATCC, GB/T, and SAE standards. A key highlight of the new Xenotest 440 is its capability to perform the globally recognized American automotive tests SAE J2412 for interior components and SAE J2527 for exterior components. Together with its highly flexible specimen holder system, the Xenotest 440 has become a truly compact all-rounder for automotive testing.

"One of my favorite features is the extension of the test libraries," said Dr. Oliver Rahäuser, Senior Product Manager at Atlas. "It makes setting up your Xenotest significantly easier."

A redesigned 10.1-inch XenoTouch® II interface improves visibility and navigation of the Xenotestwhile aligning with the Atlas Ci Weather-Ometer® and SUNTEST® instruments – offering a consistent operator experience across all Atlas’s xenon-arc platforms. Set-point monitoring functionality allows users to define all test parameter tolerances and receive real-time alerts when conditions drift beyond limits.

WXView® II connectivity enables secure, cloud-based access to active and historical test data. Users can monitor progress across locations, compare results, and generate standardized PDF reports to support quality-assurance and audit documentation.

Both models accommodate up to 38 specimens, with supported formats ranging from 90 × 75 mm to 285 × 75 mm and up to 10 mm thick – allowing labs to test everything from thin films to molded parts without requiring the footprint of larger systems. The new Xenotest 220 and 440 also feature an updated exterior design that reflects Atlas’s new industrial styling, bringing visual consistency across its entire xenon-arc portfolio.
