for 1,000 hours, connectors shall perform satisfactorily and pass succeeding tests in the qualification test
sequence.
no exposure of base metal due to electrolytic erosion. Corrosion deposits shall not be considered as
defects.
the connector for at least 20 minutes when tested in accordance with 4.5.35. During this period there shall
be no flame from outgassing or other causes on the end of the connector protected by the firewall. The
current specified in 4.5.35 shall be applied for the first 5 minutes without break in electrical continuity.
During the next minute the connector shall draw no more than 2 amperes when a test potential of 100 to
125 V ac at 60 Hz is applied between adjacent contacts and between contacts and the shell.
hermetic connectors shall be gold plated to a minimum thickness of .000050 inch (0.00127 mm).
4.5.37, contact engagement and separating forces shall be within the limits specified in MIL-C-39029.
contacts shall withstand the bending moment and depth of test probe insertion without evidence of damage
that would interfere with the mechanical or electrical performance.
Number (PIN), Date Code, manufacturer and assembly plant when applicable. The manufacturer and
assembly plants may be identified by the use of Commercial or Government Entity Number (CAGE code),
name, trademark or symbol and shall be as specified in AIR1351. Stamping shall be in accordance with
MIL-STD-1285 where space permits. Metal stamping shall be accomplished before plating. A single digit
shell size and/or insert arrangement shall be marked with a single digit (example: shell size 8 shall be
marked “8” not “08”). The following examples are illustrative:
MS number
3.39 Firewall (classes K and S connectors). Mated connectors shall prevent passing of a flame through
3.40 Contact plating thickness (hermetic). When tested as specified in 4.5.36, contacts used in
3.38 Electrolytic erosion (series III and IV). When tested as specified in 4.5.34, pin contacts shall show
3.41 Contact engagement and separating force (hermetic sockets only). When tested as specified in
3.42 Resistance to probe damage (hermetic sockets only). When tested as specified in 4.5.38,
3.43 Marking. Connectors and accessories shall be permanently marked with Part Identification
