San Antonio-based Southwest Research Institute (SwRI) has opened the 9,700-sf Network Equipment/Building Systems (NEBS) dedicated testing facility for telecommunications equipment. NEBS testing determines how equipment performs in a variety of operating conditions, and enables clients to meet an industry requirement for pre-product evaluation. Included in the facility are several environmental chambers, such as a large-platform earthquake testing facility and a large walk-in chamber. Testing categories include temperature, humidity, acoustic, seismic, and electromagnetic compatibility. SwRI, a nonprofit applied R&D organization, plans to have all NEBS equipment in place and fully operational by the end of this summer.
