d. Mount the test fuseholder in the blank panel with the rear of the fuseholder outside of the shielded

enclosure (toward the signal generator antenna). The fuseholder shall be mounted as it would be

for normal installation using the mounting hardware supplied or recommended. Repeat the

measurements of 4.6.19.2 above and calculate the shielding attenuation of the fuseholder using

the new receiver readings.

NOTE: Test panel shall be located in the chamber wall at least 1 meter from any corner and at least

1 meter from floor and ceiling.

4.6.20 Torque strength of inserts, threaded terminals, and molded threads.

4.6.20.1 Fuseholder caps. Fuseholder caps containing molded-in threaded metal inserts for

attachment to fuseholder bodies shall be assembled to the fuseholder body and subjected to the specified

torque (see 3.1 and 3.5.3).

4.6.20.2 Threaded terminals. The specified torque shall be applied to each terminal screw and to a nut

on each terminal stud (see 3.1 and 3.5.3).

4.6.20.3 Mounting. Single mounting hole fuseholders with required mounting hardware shall be

mounted on a 1/16 inch (1.59 mm) thick metal panel and the specified torque shall be applied to the

mounting nut (see 3.1 and 3.5.3).

4.6.21 Solder-lug terminals. Solder-lug terminals shall be tested in accordance with method 208 of

MIL-STD-202 (see 3.4.9) for solderability.

5. PACKAGING

5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the

contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor

personnel, these personnel need to contact the responsible packaging activity to ascertain packaging

requirements. Packaging requirements are maintained by the Inventory Control Point's packaging

activities within the Military Service or Defense Agency, or within the military service's system commands.

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.
