MIL-DTL-24211C
4.6.5 RF leakage. With a gasket, which has been coupled 5 times, inserted in a flange junction of a test line, a
known amount of RF power shall be transmitted through the line. The flange junction shall be probed to determine
the amount of RF leakage from the junction. The RF power level shall be such that leakage of at least 100 dB below
the transmitted power of the gasket is measurable. A tunable one-quarter wavelength probe shall be issued to
insure a high impedance across the junction. The center conductor of the probe shall be extended to touch one
o
flange, and the shell of the probe shall touch the mating flange. The flange shall be probed 360 and shall meet the
requirements of 3.5.
5. PACKAGING
5.1 Packaging. For acquisition purposes the packaging requirements shall be as specified in the contract or
order (see 6.2). When actual packaging of materiel is to be performed by DoD personnel, these personnel need to
contact the responsible packaging activity to ascertain requisite packaging requirements. Packaging requirements
are maintained by the Inventory Control Point's packaging activity within the Military Department of Defense Agency,
or within the Military Department's System Command. Packaging data retrieval is available from the managing
Military Department's or Defense Agency's automated packaging files, CD-ROM products, or by contacting the
responsible packaging activity.
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)
6.1 Intended use. The gaskets covered by this specification are intended for use in military applications where
their performance characteristics are required. The gaskets are suitable for installation in military systems when
used within the limitations of their specified performance requirements. These gaskets are not to be used with
cover-choke flange combinations. The gaskets specified herein must function in and withstand for prolonged
periods worldwide military unique environments. These gaskets are military unique because expensive changes to
field systems would be required to maintain proper form, fit and function, if other than these standard military
components are used.
6.2 Acquisition requirements. Acquisition documents must specify the following:
a. Title, number, and date of this specification and of the applicable specification sheet.
b. The specific issue of individual documents referenced (see 2.2 and 2.3), cf. https://assist.daps.dla.mil.
c. Packaging requirements (see 5.1).
d. The complete part number (see 3.1).
e. Unless approval is obtained from the procuring activity, the supplier must not substitute for a specified
material or fabricated part. Evidence to substantiate his claim that such a substitute is suitable must be
submitted with his request. Similar notification and substantiating evidence must be submitted at any later
time if substitution becomes necessary or desirable. At the discretion of the Government, test samples
may be required to prove the suitability of the proposed substitute.
6.3 Definition. For the purpose of this specification, the following definition applies:
6.3.1 Dissimilar metals. Dissimilar metals are defined in MIL-STD-889.
