IEEE 299-2006

This standard provides uniform measurement procedures for determining the effectiveness of electromagnetic (EM) shielding enclosures at frequencies from 9 kHz to 18 GHz (extendable down to 50 Hz and up to 100 GHz). The owner of the shielding enclosure shall provide the frequencies at which the shield will be tested, and the shielding effectiveness (SE) limits for pass/fail. This standard suggests a range of test frequencies that would provide very high confidence in the effectiveness of the shield. This standard dose not define SE limits for pass or fail.
