MIL-PRF-39017G
3.26 Fungus. All external materials shall be nonnutrient to fungus growth or shall be suitably treated to
retard fungus growth. The manufacturer shall verify by certification that all external materials are fungus
resistant or shall test the resistors as specified in 4.8.20. There shall be no evidence of fungus growth on
the external surfaces.
3.27 Marking.
3.27.1 Full marking. Resistors shall be marked with the PIN, JAN marking; date code, source code,
and manufacturer's production lot code (see 6.2). Date and source code shall be in accordance with
MIL-STD-1285. Marking shall remain legible at the end of all tests. The full marking shall be as shown in
the following example:
12345
- Source code.
7333AJ
- Date code, lot symbol, and JAN marking.
RLR32C
- Style and terminal.
1002FM
- Resistance, tolerance, and product level.
The date lot codes and lot symbols shall provide traceability through all production operations and shall
represent a specific critical point consistently provided by the manufacturer. The common manufacturing
record shall include the same date code as that on the parts covered by the record. Lot symbol shall be
assigned as in accordance with MIL-STD-1285.
3.27.2 Minimum marking. When the physical size of the resistor precludes the marking of all the above
in 3.27.1, the minimum marking required shall be as specified in the associated specification (see 3.1). In
those cases where full marking requirements are not on the resistor body, the full marking shall be
marked on the unit package (see section 5). Marking shall remain legible at the end of all tests.
3.27.3 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 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 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".
