Product Code:SAE ARP1705
Title:Coaxial Test Procedure to Measure the RF Shielding Characteristics of EMI Gasket Materials
Issuing Committee:Ae-4 Electromagnetic Environmental Effects (E3) Committee
Scope: The purpose of this procedure is to establish a technique for reliably and repeatedly measuring the RF shielding characteristics of EMI gasket materials and EMI gaskets against various joint surfaces. The procedure is also used to test the reliability of the gasketed joint combinations after being subjected to hostile environments.
