3.6 Actual effective electrical travel. Actual effective electrical travel shall be 15 turns minimum, and 30 turns
maximum.
3.7 Operating torque. Operating torque shall be a maximum of 5 ounce-inches.
3.8 Pure tin. The use of pure tin, as an underplate or final finish, is prohibited both internally and externally. Tin
content of resistor components and solder shall not exceed 97 percent, by mass. Tin shall be alloyed with a
minimum of 3 percent lead, by mass (see 6.4).
4. VERIFICATION
4.1 Sampling and inspection. Sampling and inspection shall be in accordance with MIL-PRF-22097, and as
specified herein.
4.2 Dielectric withstanding voltage. The magnitude of test voltage shall be 900 volts at atmospheric pressure, and
350 volts at reduced barometric pressure.
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 activity within the Military Service or Defense Agency, or within
the military services 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.
6. NOTES
