3.3. 1.2.2.1 Certification marks. 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 military 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 specification
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 detail specification, the manufacturer shall remove the "JAN"
or "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 No. 504,860 for the
certification mark "JAN".

assemblies, paper capacitors, and transformers. Fungus inert materials are
specified in MIL-STD-454, Requirement 4. Other materials shall be certified
fungus-resistant or shall be tested as specified in 4.7.5. The parts used
in the design shall be moisture resistant. Absorption, retention, or
release of moisture by a part shall not degrade or affect performance.
3.3.2.2 Corrosion. Corrosion prevention and control as an overall concept
shall be emphasized during design and fabrication. The distribution box
shall be designed to prevent corrosion that would adversely affect its
functions during the specified service life consistent with required
reliability and maintenance concepts. Requirements 15 and 16 of MIL-STD-454
