A security wall (under standard ICD/ICS 705) details the technical specifications for a SCIF wall (sensitive compartmented information facility). As part of the specifications, there must be a dielectric break when penetrating the wall (this helps break up any electronic transmission along the pipe). This can be done using a dielectric union, flange or coupling, but it must be listed for UFC 4-010-05 (section 3-5.8.2) for military applications.
Is there a product that acts as a dielectric break that meets this specification?
If this can't be accomplished with a dielectric break, the standard calls for grounding but does not detail how to ground the pipe. Can this just be done with grounding a single point? Has anyone used this method before?
