ASTM E2141 Accelerated Aging of Electrochromic Devices in Sealed Glass Units

Scope:

Accelerated Aging of Electrochromic Devices by ASTM E2141 test methods provide accelerated aging or durability, and performance monitoring of the time-dependent electrochromic windows. These are useful only for multilayered absorptive electrochromic coatings on sealed insulating glass units fabricated for vision glass areas employed in the buildings like windows, doors, exterior wall systems, and skylights. 

Test Procedure:

Accelerated Aging of Electrochromic Devices by ASTM E2141 test methods utilize (a) rapid current-voltage cycling tests emphasizing the electrical properties, and (b) environmental test parameters used in weatherability tests, while simulating large-area EC IGUs in real-life conditions.

Sample size:

For ASTM E2141, the samples should be at least (250±6)mm×(250±6) mm ((10±¼) ×(10±¼) inches). The identical test sample number is about 6 to 10 which is required to determine the durability of a particular construction and design.

Data:

Coloration efficiency

Photopic transmittance ratio

Conclusion:

Accelerated Aging of Electrochromic Devices by ASTM E2141 test methods provide accelerated aging or durability, and performance monitoring of the time-dependent electrochromic windows.
