AGREE Chambers

Originally designed for the military, the AGREE method of testing, an acronym for The Department of Defense Advisory Group on Reliability of Electronic Equipment, is used to perform reliability, qualification, and ESS for many industries including electronics, automotive, and telecommunications equipment. Offered in a variety of custom sizes and configurations, our AGREE vibration compatible chambers directly integrate with your electrodynamic or mechanical shaker systems, providing you flexibility in choice and testing capacity.

About AGREE Chambers

During transportation or at the site of the end-user, a product will come under some type of vibration motion. Using vibration test chambers, manufacturers can determine if a product can withstand the rigors during its normal life span. Often, vibration testing is combined with other test criteria such as temperature, in the case of our temperature vibration testing chambers, during the testing of a product. The AGREE method of testing, an acronym for The Department of Defense Advisory Group on Reliability of Electronic Equipment, was originally designed to perform specific temperature, humidity, and vibration tests in order to improve the quality and reliability of military hardware and to conform with MIL-STD 810, 781 and 883. AGREE test chambers are now used to perform reliability qualification for many industries including electronics, automotive, battery, and renewable energy.

Russells AGREE Chambers meet the requirements of MIL-STD 781A, B, and also C with incorporation of our 781C option. Their proven performance in installations around the world for many years is a testament to their superior design and construction. The easily removable chamber-to-shaker interface is designed for ease of loading and unloading of the test items. We also offer a chamber lift system to accommodate multi-axis testing. The diaphragm and frame assembly can be easily replaced with an optional solid floor plug to allow testing without vibration, if so desired.
