On the benefits of using IEEE Std 299-1997 for shielding effectiveness testing

MIL-STD-285 and the origination of IEEE Std 299 go back several decades. More recent versions of Std 299 maintained technically sound test methods, but required that all frequency ranges be applied when testing enclosures. Some frequency ranges were not available for testing at all. This paper summarizes the benefits to shield owners and users that are incorporated in the current revision of Std 299. A new, menu-driven approach matches the test of shielding effectiveness to the enclosure application. Tests are no longer limited to just "high performance" enclosures, test subjects may be of any shielding material and construction, and they may be as small as 2 meters in any linear dimension.
