MIL-PRF-31031B
3.29 Solderability. Connectors shall be tested as specified in 4.6.26. Solder joints between the
connector and the cable outer conductor and between the center contact and cable inner conductor shall
withstand the specified forces.
3.30 Safety wire hole pullout. When applicable (see 3.1), connectors are to be tested as specified in
4.6.27. There shall be no evidence of hole tear-out.
3.31 Thermal vacuum outgassing. When tested in accordance with 4.6.28, all nonmetallic materials of
the connector assembly shall have maximum total mass loss (TML) of 1.0% of the original specimen
mass and shall have a maximum volatile condensable material (VCM) content of 1.0% of the original
specimen mass.
3.32 Flammability. When tested in accordance with 4.6.29, nonmetal materials shall be considered
nonflammable or self-extinguishing if less than 6 inches of the minimum use thickness sample is
consumed and the time of burning does not exceed 10 minutes. There shall be no sparking, sputtering,
or dripping of flaming particles from the test sample.
3.33 Odor. When tested in accordance with 4.6.30, nonmetal materials shall rate not greater than 2.5.
3.34 Toxicity (offgassing). When tested in accordance with 4.6.31, all nonmetal materials shall have a
total hazard index value less than 0.5.
3.35 Marking. Connectors and associated fittings shall be permanently and legibly marked in
accordance with the marking requirements of MIL-STD-130 with the PIN (see 1.1.2), the manufacturer's
CAGE code and final assembly date code. All parts manufactured to this specification shall be marked
unless specific exceptions are granted on the specification sheet. The marking location is optional; when
practical, a location should be picked that will least likely be covered in cable assembly or installation.
NOTE: Date code marking requirements shall be in accordance with MIL-STD-1285.
3.36 JAN brand. The United States Government has adopted, and is exercising legitimate control over
the certification marks "JAN" and "J", respectively, to indicate that items so marked or identified are
manufactured to, and meet all the requirements of specifications. Accordingly, items acquired to, and
meeting all of the criteria specified herein and in applicable specifications shall bear the certification mark
"JAN" except that items too small to bear the certification mark "JAN" shall bear the letter "J". The "JAN"
or "J" shall be placed immediately before the PIN except that if such location would place a hardship on
the manufacturer in connection with such marking, the "JAN" or "J" may be located on the first line above
or below the PIN. Items furnished under contracts or orders which either permit or require deviation from
the conditions or requirements specified herein or in applicable specifications shall not bear "JAN" or J".
In the event an item fails to meet the requirements of this specification and the applicable specification
sheets or associated performance specifications, the manufacturer shall remove completely the military
pin and the `JAN' or the J" from the sample tested and also from all items represented by the sample.
The "JAN' or "J" certification mark shall not be used on products acquired to contractor drawings or
specifications. The United States Government has obtained Certificate of Registration Number 504,860
for the certification mark `JAN' and Registration Number 1,589,261 for the certification mark "J".
Note: The "JAN" or "J" is not part of the PIN.
3.37 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 fit,
serviceability, or appearance. Threads shall be examined under a X10 power lens for plating; burrs,
flaking, etc., shall not be permitted.
