IEEE 299-2006

IEEE Standard Method for Measuring the Effectiveness of Electromagnetic Shielding Enclosures

Uniform measurement procedures and techniques are provided for determining the effectiveness of electromagnetic shielding enclosures at frequencies from 9 kHz to 18 GHz (extendable to 50 Hz and 100 GHz, respectively) for enclosures having all dimension greater than or equal to 2.0 m. The types of enclosures covered include, but are not limited to, single-shield or double-shield structures of various construction, such as bolted demountable, welded, or integral with a building; and made of materials such as steel plate, copper or aluminum sheet, screening, hardware cloth,metal foil,or shielding fabrics.

299.1-2013

IEEE Standard Method for Measuring the Shielding Effectiveness of Enclosures and Boxes Having all Dimensions between 0.1 m and 2 m

This standard provides uniform measurement procedures for determining the shielding effectiveness of electromagnetic (EM) shielding for a variety of enclosures and boxes having all dimensions between 0.1 m and 2 m in the radio frequency range not addressed by IEEE Std 299(TM)-2006. This standard is divided into two parts: Part I - 0.75 m to 2 m and Part II - physically small (< 0.75 m) but electrically large enclosures. In addition to a number of annexes aiding the measurement of shielding effectiveness of these enclosures, Annex I addresses physically small and electrically small enclosures, and Annex J addresses electrically small enclosures in reverberation chambers. Problems occurring in the testing of small enclosures having linear dimension less than 2 m are very different from determining the shielding effectiveness of large rooms and broad depending on the actual size of the enclosure itself. A number of other annexes are included that address rationale, mathematical formulas, selection of measurement techniques, preliminary measurement and repairs, wall-mounted monopoles, impedance mismatch correction, and using isolated monopoles in outer reverberation chambers.

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


299-1997

IEEE Standard Method for Measuring the Effectiveness of Electromagnetic Shielding Enclosures

Superseded by IEEE Std 299-2006. Uniform measurement procedures and techniques are provided for determining the effectiveness of electromagnetic shielding enclosures at frequencies from 9 kHz to 18 GHz (extendable to 50 Hz and 100 GHz, respectively) for enclosures having no dimension less than 2.0 m. The types of enclosures covered include, but are not limited to, single-shield or double-shield structures of various construction, such as bolted demountable, welded, or integral with a building; and made of materials such as steel plate, copper or aluminum sheet, screening, hardware cloth, metal foil, or shielding fabrics.

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
