1.2.1 Regularly Engaged
As it applies to the testing company is defined to mean that the testing company has successfully performed electromagnetic
shielding attenuation (SA) test and shielded enclosure leak detection system (SELDS) tests at least [six] [_____]
times in the last [two] [_____] years.
1.2.2 Independent
As it applies to the testing company is defined to mean that the company has no financial interest and not directly
or indirectly part of the shielding Contractor, subcontractor, or general contractor QC organization.
1.2.3 Shielding Attenuation
As it applies to this section is defined as the shielding effectiveness. Shielding effectiveness at a test area
for the purpose of this procedure is the ratio expressed in decibels (dB), of the received signal when the receiving
antenna is illuminated by electromagnetic radiation in the test calibration configuration (no shield present)
to the received signal through the electromagnetic barrier in the test measurement configuration. Assuming that
antenna voltage is detected.
SE = 20 log(Vc/Vm)
Where Vm is the measured signal at the test area and Vc is the calibration signal at the same frequency and transmitting
antenna polarization. Shielding effectiveness values are test-method dependent and different values may be obtained
when time-domain or other frequency-domain measurement techniques are used.
1.2.4 Corrections and Repair
Replacing existing defective part(s) with identical parts which are shown in approved shop drawings, parts list,
catalog, and maintenance manual. This includes cleaning, adjustment, and tightening.
