Full Description

Scope

This standard provides uniform measurement procedures for determining the effectiveness ofelectromagnetic (EM) shielding enclosures at frequencies from 9 kHz to 18 GHz (extendable down to50 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.

Purpose

The purpose of this standard is to provide the following:a) A standard procedure for the measurement of the effectiveness of shielded enclosures, in abroad range of radio frequencies (RFs), including a minimum set of recommended frequenciesb) Identical procedures applicable to frequencies other than the standard setc) An optional measurement technique to detect the nonlinear behavior of high-permeabilityferromagnetic enclosures (see Annex C)

Abstract

Revision Standard - Active.Uniform measurement procedures and techniques are provided for determining theeffectiveness 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 thanor equal to 2.0 m. The types of enclosures covered include, but are not limited to, single-shield ordouble-shield structures of various construction, such as bolted demountable, welded, or integralwith a building; and made of materials such as steel plate, copper or aluminum sheet, screening,hardware cloth, metal foil, or shielding fabrics.
