MIL-DTL-22992G
4.6.13 Salt spray (corrosion) (see 3.16). Unmated connectors and individual contact samples shall
be tested in accordance with test procedure EIA-364-26, test condition B. The following details and
exceptions shall apply:
a. The connectors shall be tested for 452 hours mated followed by 48 hours unmated.
b. The connectors shall not be mounted, but shall be suspended from the top of the chamber
using waxed twine or string, glass rods or glass cord.
c.
Wire ends shall be protected to prevent salt migration. After the salt spray exposure, the
remaining number of durability cycles specified in 4.6.12 shall be completed.
4.6.14 Cable pulI-out (see 3.17). Cables assembled in the connector adapter, but with the
conductors not attached to the contacts, shall be subjected to the axial tensile load pull-out force specified
in table V. The amount of slippage shall be measured between the cable and the connector adapter.
The specified load shall be applied for a minimum of 1 hour. When cable grips are an integral part of the
adapter or connector assembly, they shall be used.
4.6.15 Vibration (see 3.18). Connectors with suitable adapters shall be tested in accordance with
test procedure of EIA-364-28. The following details and exceptions shall apply:
a.
Test condition number: III.
b.
Counter part plugs shall be engaged with the mounted receptacles and held by normal
locking means only. No safety wire shall be used.
c.
The vibration of the receptacle and fixture shall be monitored by a suitable sensor at a
point or on the fixture near a receptacle support point or on the receptacle itself.
d.
All contacts shall be wired in a series circuit with at least 100 milliamperes of current
flowing through the series circuit during vibration.
e.
The cable or wire bundle shall be clamped to non-vibrating points at least 8 inches from
the rear of the connectors. The clamping length may be selected or changed to avoid
resonance of the cable or wire.
f.
The grounding contacts of class L grounding connectors shall not be wired into the series
monitoring circuit.
4.6.16 Drop (class L) (see 3.19) (qualification only). Cabled, unmated line connectors (MS90556 and
MS90557) with protective covers assembled shall be tested. Cables shall be inserted through an
84 inch +2 inch 0 inch (2134 mm +50.8 mm 0 mm) length of standard commercial conduit or similar
tube of sufficient diameter to freely accommodate the cable and shall be taped to the conduit so the
connector cable grip is 2 inch +2 inch 0 inch (50.8 mm +50.8 mm 0 mm) from the end of
the conduit. The other end of the conduit with the cable extending, shall be pivoted at a point
24 inch +1 inch 0 inch (610 mm +25.4 mm 0 mm) above the horizontal surface of solid, adequately
aged concrete. The pivot shall be capable of rotating 360 and shall not impede or retard the connector's
free fall to the striking surface. The connector shall be raised by the cap retention lanyard to a point so
that the base of the connector (gland nut) is 72 inch +6 inch 0 inch (1829 mm +153 mm 0 mm) above
the striking surface and allowed to free fall to the striking surface. The connector shall be dropped 10
times, rotating the connector after each free fall, so that the connector strikes the concrete in each of 10
different radial positions approximately 36 apart. The cable shall then be removed from the conduit, and
the shells and inserts shall be examined (see figure 3).
