AGREE Test Chamber - RDV-32-10-10-WCRDV-32-10-10-WC

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 another test criteria such as temperature, in the case of our temperature vibration testing chambers, during 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 781 and 883. AGREE test chambers are now used to perform reliability, qualification, and ESS for many industries including electronics, automotive, and telecommunications equipment.

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.

Our chambers are designed for use with mechanical, electro-dynamic, and dual axis vibration systems. Russells assumes the responsibility for compatibility of the chamber and vibration system giving you the flexibility to use any vibe system.

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.
