MIL-C-62F
3.23.1 Soldering. All excess flux and solder shall be removed. Electrical connections shall be mechanically secure
before soldering, when possible, and electrically continuous after soldering.
3.24 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.
4. VERIFICATION
4.1 Classification of inspection. The inspection requirements specified herein are classified as follows:
Qualification inspection (see 4.3).
a.
b.
Conformance inspection (see 4.4).
(1) Inspection of product for delivery (see 4.4.1).
4.2 Inspection conditions and methods.
4.2.1 Conditions. Unless otherwise specified herein, all inspection shall be made at or referred to 25C 3C, and
at room ambient relative humidity and pressure. Unless otherwise specified, when tests are made at other than
25C, the tolerance shall be 3C. At temperatures higher than 35C, adequate circulation of air shall be provided to
maintain the required temperature within the specified tolerance.
4.2.2 Methods.
4.2.2.1 AC measurements. Alternating-current (ac) measurements shall be made at the frequency specified. The
magnitude of the ac voltage shall be limited to 1.0 volt root mean square (rms). The dc polarizing voltage, if applied,
shall be greater than the peak ac voltage; the sum of the peak ac and polarizing voltage shall not exceed the dc rated
voltage (see 3.1).
4.2.2.2 Reference measurements. When requirements are based on comparative measurements made before
and after conditioning, the reference measurement shall be considered the last measurement made at 25C prior to
the conditioning. The reference measurements shall have been made within 30 days prior to the beginning of
conditioning.
4.3 Qualification inspection. Qualification inspection shall be performed at a laboratory acceptable to the
Government (see 6.2).
4.3.1 Sample. The number of sample units comprising a sample 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.
4.3.2 Test routine. Sample units shall be subjected to the qualification inspection specified in table IV, in the order
shown. Two sample units shall be subjected to the visual and mechanical examination (internal). The remaining
sample units shall be subjected to the subsequent inspection of group I. The sample units shall then be divided as
specified in table IV for groups II to VI, inclusive. The sample units shall then be subjected to the inspection for their
particular group.
4.3.3 Defectives. Defectives in excess of those allowed in table IV shall be cause for refusal to grant qualification
approval.
