MIL-PRF-11021H
3.8 Workmanship. Workmanship shall be in accordance with the manufacture of a high
quality switch. This shall be evidenced by the absence of faults which are detrimental to the
appearance, serviceability, and durability of the switch, and free from burrs, chips, dirt, sharp
edges, scratches, unauthorized use of used or reworked parts, and improper preparation and
assembly of the switch (see 4.5.2).
4. VERIFICATIONS
4.1 Inspection equipment. Unless otherwise specified in the contract, the supplier is
responsible for the provision and maintenance of all inspection equipment necessary to assure
that supplies and services conform to contract requirements. Commercial, modified commercial,
or supplier designed inspection equipment or measuring set-ups must be capable of repetitive
measurements to an accuracy of 10 percent of the component tolerance. Calibration of inspection
equipment shall be in accordance with ISO 10012. Voltage (voltmeter, DC) and current
(ammeter, DC) measuring instrument tolerances shall have a maximum error of 1 percent.
4.1.2 Materials and construction. Conformance to 3.2 through 3.3.7, inspection, and
material certification records shall be maintained by the contractor. Records shall be subject to
review by the Government and shall include the date, part, characteristic identification,
inspection results, and disposition of lot (accepted or rejected). Corrective action taken on noted
defects shall be subject to approval by the Government.
4.1.3 Physical characteristics. Conformance to 3.2 through 3.3.7 shall be determined by
visual and tactile examination, and measurement with standard inspection equipment.
4.2 Classification of inspections. The inspection requirements specified herein are
classified as follows:
a. First article inspection (see 4.4).
b. Quality conformance inspections (see 4.5).
1. Examination (see 4.5.2).
2. Acceptance tests (see 4.5.3.1).
3. Control tests (4.5.3.2).
4.3 Inspection conditions. Except where otherwise specified herein, tests shall be
performed in ambient still air temperatures of 80 + 5°F and a test voltage of 28 + 2 VDC. Test
currents shall be maintained automatically or manually at specified values. The resistance REquiv
(from Figures 2 and 3) shall be adjusted to equal the resistance RCB + 5%. Where possible, the
circuit shall be adjusted after switching in the switch assembly to yield the instrument readings
specified in the applicable test. Current conducting cables shall conform to MIL-DTL-13486 and
shall be exposed to the same ambient air temperatures as specified for the switch assembly. Test
cables shall be 5 feet long and contain size 14 gauge conductors. The test cables shall be attached
to a connector conforming to 7723494 to form a cable assembly. No more insulation than
necessary to form electrical contact shall be removed from the cables. The switch assembly shall
be engaged to the specified cable assembly using only the normal locking means of the
connector. All tests shall be conducted on the intact switch assembly. Power shall be applied to,
