MIL-PRF-83530C
3.29 Marking. The resistors shall be marked with the PIN, manufacturer's CAGE, date code and lot code. The
part number may appear on two lines and in such case shall be divided between the / and the specification sheet
number. The date code shall be the date of the final assembly operation for the production lot as defined in 4.6.1.1.2.
The following is an example of the marking:

3.30 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally
preferable materials should be used to the maximum extent possible provided that the material meets or exceeds the
operational and maintenance requirements, and promotes economically advantageous life cycle costs.
3.31 Workmanship. Resistors shall be processed in such a manner as to be uniform in quality and free from
defects that may adversely affect operability, reliability or appearance. The wire leads or terminals shall be unbroken,
and not crushed or nicked.
4. VERIFICATION
4.1 Classification of inspection. The inspection requirements specified herein are classified as follows:
a.
Qualification inspection (see 4.4).
Conformance inspection (see 4.6).
b.
Periodic inspection (see 4.7).
c.
4.2 Test equipment and inspection facilities. The supplier shall establish and maintain a calibration system in
accordance with NCSL Z540-1, ISO 10012-1, or equivalent system as approved by the qualifying activity.
4.3 Inspection conditions and precautions.
4.3.1 Conditions. Unless otherwise specified herein, all inspections shall be performed in accordance with the
4.3.2 Precautions. Adequate precautions shall be taken during tests to prevent condensation of moisture on
resistors, except during the moisture resistance tests.
4.4 Qualification. Qualification inspection shall be performed at a laboratory acceptable to the Government
(see 6.3) on sample units produced with equipment and procedures normally used in production.
4.4.1 Sample. The number of sample units comprising a sample of resistors to be submitted for qualification
inspection shall be 52. The sample shall be taken at random from a production run, and shall be produced with
equipment and procedures normally used in production. Each voltage rating of each resistor style shall be qualified
separately.
4.4.2 Test routine. Sample units shall be subjected to the qualification inspection specified in table II, in the order
shown. All sample units shall be subjected to the inspection of group I. The 52 sample units from group I shall then
be divided as specified in table II for groups II to V inclusive, and subjected to the inspections for their particular
group.
4.4.3 Failures. Failures in excess of those allowed in table II shall be cause for refusal to grant qualification.
