MIL-C-5G
3.18.2 Partial marking. When space or existing molds do not permit the marking specified in 3.18.1, the type
designation, manufacturer's name or symbol, and where applicable (see 3.1), the current rating at 1 MHz, shall be
marked on the capacitor. If lack of space requires it, the type designation may appear on two lines. In this event, the
type designation shall be divided as shown in the following example:
CM15CD
010DN3
An abbreviated type designation marking will be permitted for styles CM04 and CM09 as follows:
CM4ED
101JO
3.18.3 Established reliability (ER) marking. An ER part manufactured in accordance with MIL-PRF-39001 may be
marked and furnished as a non-ER part to this specification, if produced on the same assembly line or lines, and
provided it is subjected to and meets all the inspection requirements of the ER part. This is applicable only to group 1
of 4.5.1.1.
3.19 Workmanship. Capacitors shall be processed in such a manner as to be uniform in quality and shall be free
from pits, corrosion, cracks, rough edges, and other defects that will affect life, serviceability, or appearance. All
traces of corrosive flux shall be removed.
4. VERIFICATION
4.1 Test equipment and inspection facilities. The supplier shall establish and maintain a calibration system in
accordance with ANSI/NCSL Z540-1, ISO-10012-1, or equivalent, as approved by the qualifying activity.
4.2 Classification of inspections. The inspections specified herein are classified as follows:
a. Qualification inspection (see 4.4).
b. Conformance inspection (see 4.5).
4.3 Inspection conditions. Unless otherwise specified herein, all inspections shall be performed in accordance
with the test conditions specified in "GENERAL REQUIREMENTS" of MIL-STD-202.
4.4 Qualification inspection. Qualification inspection shall be performed at a laboratory acceptable to the
Government (see 6.3).
4.4.1 Sample size. The number of capacitors to be submitted for qualification inspection shall be as specified in
the appendix to this specification. The sample shall be taken from a production run and shall be produced with
equipment and procedures normally used in production.
4.4.2 Inspection routine.
4.4.2.1 Single-type submission. The specimens (see A.2.1.1) shall be subjected to the examinations and tests
specified in table VII, in the order shown. All specimens shall be subjected to the examinations and tests of group I.
The specimens shall then be divided into the remaining groups as shown in table VII, and subjected to the tests for
their particular group.
4.4.2.2 Single-style submission. The specimens (see A.2.1.2) shall be subjected to the electrical tests of group I
and the temperature-coefficient and capacitance-drift test of table VII only. Only one defective shall be allowed.
4.4.3 Defectives. Defectives in excess of those allowed in table VII and 4.4.2.2 shall be cause for refusal to grant
qualification.
