The current version is IEEE299-1997. Please use this version since it differs substantially from the earlier 1991 version. This is the version that was evaluated by the military in favor of which MIL STD 285 was abolished. The 1997 version is a substantial improvement over IEEE299-1991, both technical and in flexibility. The old version mandates an extensive number of tests, making testing prohibitively expensive (or lucrative for the shield room testers). These mandatory requirements have been abandoned in favor of a more flexible suggested test procedure with frequencies and tests performed "as needed" for the application of the shielded room.
