3.3.6
Filter Installation
**************************************************************************
NOTE: When the filter unit must be installed inside
the shielded enclosure, the input terminal
compartment will be EM-tight instead of the load
terminal compartment, and the filters will be
located in the load terminal compartment. This
arrangement is necessary to prevent radiated EM
energy within the shielded enclosure from inducing
EM energy in the power conductors between the
filters and the point where the conductors pass
through the shielded enclosure wall. To provide for
this arrangement, change the wording as necessary;
i.e., change the word "load" to read "input" and
change the words "input" to read "output" or "load,"
as appropriate.
**************************************************************************
Filters shall be supported independently of the wall shielding.
Inspections shall be conducted on filters provided under this
specification, to verify compliance with the specified requirements.
Filters shall be shipped after successful testing and shall be examined
prior to installation to determine if damage occurred during shipment.
Damage, no matter how slight, will be reason for rejection of the filter.
3.4
WAVEGUIDE INSTALLATION
Penetrations of the EM shield shall be treated with the appropriate
waveguide method. Waveguides shall be suitable for piping and for fluids
or gases contained within, in accordance with specified requirements.
3.5
SHIELDING PENETRATION INSTALLATION
Penetrations shall be installed in accordance with requirements of the
penetration schedule and coordinated with system installation.
3.6
QUALITY ASSURANCE
Quality Control Plan
A quality control plan shall be developed to assure compliance with
contract requirements and quality control records shall be maintained for
construction operations required under this section. The quality control
plan shall be submitted to the Contracting Officer. A copy of testing
records, as well as the records of corrective actions taken, shall be
furnished. The in-progress and final acceptance testing of EM shielding
and penetration protection system work shall be performed as specified.
Deficiencies shall be corrected at no additional cost to the Government.
Legible copies of the daily inspection reports shall be maintained by the
shielding specialist at the project site, and the copies of the
Construction Quality Control Report shall be delivered to the Contracting
Officer on the third workday following the date of the report. The daily
inspections shall include the type of work being performed during the
report period and locations, type of testing, deficiencies, corrective
actions, unsolved problems, and recommendations to assure adequate quality
control. Results of inspections and tests performed in accordance with
this specification shall be attached to the daily Construction Quality
