MIL-DTL-83526C
3.11.4.1 Connector, backshell and accessory. The connector, backshell and accessory parts shall be
identified by a legible and permanent marking applied in accordance with MIL-STD-1285.
3.11.4.2 Terminus location identification. Terminus location shall be designated with identifiable
characters as indicated on the applicable specification sheet (see 3.1). Raised characters shall not be
used on mating faces. All positions shall be identified on the front of the insert except where space
limitations make this impracticable. Location of terminus identifying characters shall be in close proximity
to the terminus but need not be placed exactly where indicated on the standard. The preferred color of
the terminus location identification character is white. When the background is a color against which
white is difficult to distinguish, a color will be chosen for which the identifying character can be easily
distinguished. Character position and arrangement shall assure appropriate terminus cavity identification.
3.11.4.3 JAN and J marking. 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 part number 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 part number. 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 specifications, the manufacturer shall
remove completely the military part number 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
1,586,261 for the certification mark "J"."
3.11.5 Terminus cleaning. After cleaning the terminus in accordance with 4.9.5, the marking
requirements of 3.11.4 shall be met; also the requirements of 3.10.1 shall be met before, during, and after
the test.
3.11.6 Insert retention axial strength. When tested in accordance with 4.9.6, connector inserts shall
withstand an applied minimum pressure of 100 pounds per square inch (69 Mpa) in both the forward
direction and the backward direction for a minimum period of one minute without cracking, breaking, or
being dislocated from their normal position in the connector shell. No axial displacement detrimental to
performance shall be observed between the inserts and their shell body during or after the test exposure.
The requirements of 3.10.1 shall be met during and after the test.
3.11.7 Insert retention radial strength. When tested in accordance with 4.9.7, connector inserts shall
withstand the clockwise and counter clockwise radial torque specified (see 3.1) when held for a minimum
period of one minute in each direction. No rotational displacement detrimental to performance shall be
observed between the inserts and their shell body during or after the test exposure.
3.11.8 Terminus retention force. When tested in accordance with 4.9.8, and subjected to axial loads of
22.0 pounds, locked termini shall be retained in their inserts and axial displacements of the termini shall
not exceed .012 inch. No damage to termini or inserts shall occur.
3.11.9 Terminus insertion and removal forces. When tested in accordance with 4.9.9, the insertion
force and the force required to remove unlocked termini shall not exceed 22.0 pounds.
