Demonstrate Good Shielding Practices
Certain guidelines must be followed to retain the RF shielding integrity of the
chamber. These good shielding practices consist of the following:
 Doors must be periodically cleaned and lubricated.
 Screw-retaining items mounted within the enclosure must not
penetrate through both shields of a modular panel system. Screws
must not penetrate the screen system of a Series 60 at all.
 Framing screws must never be used to fasten items within the
enclosure.
 When a hole is bored for a new penetration, all burrs must be removed
and both the perimeter of the hole and the penetration must be
cleaned with a cleaning agent before installing the new penetration.
 Nothing must penetrate the enclosure wall, floor, or ceiling without use
of a proper electromagnetic-designated penetration.
