Abstract : Buried conduit systems form an integral part of the EMP shielding in large hardened missile systems such as SAFEGUARD to protect the communications, control, and power cabling from NEMP effects. To initially verify conduit system hardness and to ensure that it is maintained over the system life, nondestructive testing techniques are being developed to detect and locate their flaws that could adversely affect EMP hardness and to measure their impact on system hardness. Several testing techniques that have been developed are discussed, and experimental data are presented from measurements on buried conduits.
