MIL-C-38983A
4.3 Gages. The contractor shall provide gages as necessary to ensure that the material to which this
specification applies will meet the dimensional requirements shown on the applicable drawings.
4.4 Acceptance tests. The acceptance tests shall consist of those indicated in table II. The sequence of
tests shall be in the order indicated in table II.
4.4.1 Packing, packaging, and marking. Inspection shall be conducted in accordance with the inspection
criteria on the applicable drawings as referenced in section 5.
4.5 Tests.
4.5.1 Visual inspection. Each cartridge in the production lot shall be visually inspected for the criteria
given in 3.4.1.
4.5.2 Drawing conformance. Each cartridge in the first article sample or the acceptance sample shall be
inspected to determine conformance with Drawing 69E14000 and applicable specifications.
4.5.2.1 Metal parts inspection. Metal parts shall be inspected for conformance to drawing requirements,
presence of metal defects (cracks, splits, cold shuts, inclusions, burrs, or porosity), and plating defects.
4.5.3 Radiographic examination. Each cartridge in the first article sample and acceptance sample shall
be radiographically examined in accordance with MIL-STD-453. The cartridge shall be x-rayed with the long
axis of the cartridge perpendicular to the rays of the machine. All cartridges shall be arranged on trays or
boards in consecutive numerical order and each radiograph plate shall be identified by date, cartridge part
numbers, lot number, and range of serial numbers. The plates shall be examined to determine compliance with
the requirements of Drawing 69E14000 and this specification.
4.5.4 Bridge Circuit Resistance. The resistance of each bridge circuit shall be measured within an
accuracy of one percent using a test circuit which subjects the bridge circuit to a current of less than 50
milliamperes. This test shall apply to all cartridges in the production lot, first article sample, and lot
acceptance sample.
4.5.5 Leakage. Each cartridge in the first article test sample or lot acceptance test sample shall be leak
tested in a dry gas or dry air leak tester. Cartridges which exhibit leak rate in excess of 10-4 cubic centimeters
of gas or air per second at a pressure differential of 1.0 ± 0.1 atmosphere shall be considered defective. If one
or more cartridges of the acceptance test sample exhibit a leakage defect, then a 100 percent leak test of the
production lot represented shall be required at no additional expense to the Government. Cartridges which
exhibit a leak rate in excess of that specified above shall be rejected.
4.5.6 Power-current test. Each cartridge in the first article and acceptance test sample shall have a direct
current of not less than one ampere supplying a minimum of one watt to each bridge circuit for a period of not
less than 5 minutes. The two bridge circuits in each cartridge shall be tested in series circuit simultaneously.
The test current shall be regulated throughout the period of application to within 2 percent. If a rectified
current is used, the ripple content shall not exceed 5 percent root mean square of the test current. Test
temperature is ambient. The cartridge shall not fire during the test and shall perform acceptably when
ballistically tested.
