MIL-DTL-24231E(SH)
TABLE I. First article, conformance, and single item inspection Continued.
NOTES:
1/
The insulation resistance test (see 4.5.1) shall be performed before, during, and after the hydrostatic test.
The continuity test shall be performed before and after the hydrostatic pressure test.
2/
The insulation resistance test and continuity test shall be performed before the 0 to 100 lbf/in2 test and after
the 0 to 2000 lbf/in2 test.
3/
Molded plugs mated to matching receptacles shall also be tested during the hydrostatic pressure test.
4/
Underwater explosion testing can be waived from first article upon both satisfactory underwater explosion
performance of the parent design and satisfactory compliance with all other first article requirements.
4.4 Examinations.
4.4.1 Visual and mechanical examination. Pressure-proof fittings and single items (see 4.5.12) shall be
examined to verify that materials, design, construction, physical dimensions, marking, and workmanship are in
accordance with the requirements specified herein and in the specification sheets (see 3.1, 3.3, 3.4, 3.6, and 3.7).
4.5 Tests.
4.5.1 Insulation resistance. Insulation resistance tests shall be in accordance with Method 302, Test Condition
B of MIL-STD-202. The points of measurement shall be as follows:
a.
Single cable and multiple cable connectors, receptacles, and adapters:
(1) Conductor to conductor.
(2) Conductor to ground.
(3) Conductor to shield.
(4) Shield to ground.
b.
Molded plugs:
(1) Conductor to conductor.
(2) Conductor to ground.
(3) Conductor to shield.
(4) Shield to ground.
When pins are exposed to water, no insulation resistance tests shall be conducted during the hydrostatic
pressure tests. Insulation resistance readings shall be in accordance with 3.5.1.
4.5.2 Dielectric withstanding voltage. Electric pressure-proof fittings shall be tested in accordance with
Method 301 of MIL-STD-202 to determine conformance to 3.5.2. The following shall apply:
a. Magnitude of test voltage: 1600 volts root mean square (Vrms) or the value specified on the applicable
cable or wire specification sheet (see 3.1), whichever is lower.
b.
Nature of potential: alternating current (AC).
c. Points of application of test voltage: between any two adjacent contacts and between the metal portion of
the connector and contact.
4.5.3 Continuity check. Using an ohmmeter, a continuity check shall be performed on the fitting types and at
