MIL-PRF-49142B
3.23 Coupling mechanism retention force. When tested as specified in 4.6.20, the coupling
mechanism shall not be dislodged from the connector and shall be capable of meeting the requirements
of 3.5.1 immediately after the test.
3.24 RF leakage. When connectors are tested as specified in 4.6.21, the total leakage cable to cable
shall not exceed that specified (see 3.1).
3.25 Risetime degradation. When connectors are tested as specified in 4.6.22, the risetirne
degradation shall be less than 400 picoseconds (ps).
3.26 Connector durability. When connectors are tested as specified in 4.6.23, they shall show no
evidence of severe mechanical damage and the coupling device shall remain functional. Connectors
shall meet the applicable requirements of 3.5 and 3.7.
3.27 Marking. Connectors and associated fittings shall be permanently and legibly marked in
accordance with the general marking requirements of MIL-STD-1285 with the military PIN and the
manufacturer's federal supply code. The marking location is optional when practicable, a location should
be picked that will least likely be covered in cable assembly or installation.
3.28 Workmanship. Connectors and associated fittings shall be processed in such a manner as to
be uniform in quality and shall be free from sharp edges, burrs and other defects that will affect life,
serviceability or appearance.
3.29 Assembly instructions. Complete assembly instructions shall be furnished by the vendor with
each connector supplied under this specification (see 6.2).
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as
follows:
a. Qualification inspection (see 4.3).
b. Conformance inspection (see 4.5).
c. Periodic inspection (see 4.5.2).
4.2 Inspection conditions. Unless otherwise specified, all inspections shall be performed in
accordance with the test conditions specified in the `GENERAL REQUIREMENTS of MIL-STD-202 or EIA
364. For each test of threaded coupling connectors, where the test is performed on mated pairs, the pair
shall be torqued to the specified value (see 3.1).
4.3 Qualification inspection. Qualification inspection shall be performed at a laboratory acceptable to
the Government (see 6.3) on sample units produced with equipment and procedures normally used in
production.
4.3.1 Sample size. Twenty five class 1 connectors of the same PIN with its mating connector or
fifteen class 2 connectors of the same PIN with its mating connector (see 1.2.1) shall be subjected to
qualification inspection.
4.3.2 Group qualification. For group qualification of all series of connectors covered by this
specification (see 3.1). Group qualification will be limited to those connectors for which evidence of
manufacturing capability is demonstrated by providing engineering drawings to the qualifying agency.
The Government reserves the right to authorize performance of any or all qualification inspection of
additional types in the group that are considered necessary for qualification within each group.
