APPENDIX A
PROCEDURE FOR QUALIFICATION INSPECTION
A.1. SCOPE
A.1.1 This appendix details the procedure for submission of samples for qualification inspection of capacitors
covered by this specification. The procedure for extending qualification of the required sample to other capacitors
covered by this specification is also outlined herein. This appendix is a mandatory part of the specification. The
information contained herein is intended for compliance.
A.2. SUBMISSION
A.2.1 Sample.
A.2.1.1 Single-type submission. Sets of 43 capacitors shall be submitted for each type for which qualification is
sought. Each sample set shall be submitted in the J (± 5 percent) or closer capacitance tolerance.
A.2.1.2 Single-style submission. An additional sample set of 12 capacitors shall be submitted with each sample
set of 43 capacitors. The specimens of this additional sample set shall be in the same capacitance tolerance and
temperature range, and shall be of the same design, construction, and materials as the corresponding specimens
selected in accordance with A.2.1.1, and shall have the lowest capacitance value listed for the particular style,
characteristic, and capacitance tolerance. Where the lowest capacitance value listed for a particular style is below
45pF, specimens of the 47pF value, or preferably lower, may be submitted. The additional sample units shall be
subjected to the group I tests of table A-I and shall represent 50 percent of those units subjected to the temperature
coefficient and capacitance drift tests of group IV.
A.2.2 Qualification-group submission. Table A-I shows the number and types of specimens to be submitted for
the styles constituting a qualification-group submission. The characteristics submitted shall be of the narrowest
temperature coefficient for which qualification is desired, and shall be in either foil or silvered-mica construction. The
temperature range of the specimens submitted shall be the same.
A.3. EXTENT OF QUALIFICATION
A.3.1 Submission and qualification of a particular style in one of characteristics C, E, or F and in one of
temperature ranges N, O, or P automatically carries with it broader requirements, provided the units are of the same
style, material, and construction (e.g., qualification of characteristic F includes qualification and characteristics C and
E of the same design; qualification of temperature range P includes qualification of temperature ranges N and O of
the same design). Qualification of the ± 5 percent or closer capacitance tolerances automatically qualifies all other
applicable capacitance tolerances. Qualification of a style is limited to the maximum watt-second rating and the
highest voltage submitted. Qualification of either straight lead style or crimp lead style allows qualification of the other
lead style.
A.3.2 Qualification groups. Qualification of all the types submitted as a complete qualification group (see table A-I)
automatically carries with it qualification of all types for the styles included in the group which have characteristics of
equal or broader requirements than the types submitted, and of temperature ranges equal to and narrower than the
type submitted. This extension of qualification is contingent on the use of the same materials, design, and
construction for all types qualified in the qualification group. Wherever material, design, or construction differences
