APPENDIX
PROCEDURE FOR QUALIFICATION INSPECTION
10. SCOPE
*
10.1 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.
20. SUBMISSION
20.1 Sample.
20.1.1 Single-style submission. A sample consisting of 63 sample units of each type for which qualification is
sought shall be submitted.
20.1.2 Combined-voltage submission. A sample consisting of 51 sample units of the highest capacitance value
and 13 sample units of the lowest capacitance value, but not lower than 47 pF, in each style, dc rated voltage, and
lead diameter (for styles where an optional lead diameter is allowed) for which qualification is sought shall be
submitted. The sample units shall be in the J (5 percent) or closer capacitance tolerance. The sample units
subjected to groups II and IV of table III shall be composed of the highest capacitance values represented in the
submission, and the sample units subjected to groups III and V shall be composed of equal numbers of the highest
and lowest capacitance values represented. The sample units shall then be subjected to the inspection for their
particular group.
30. EXTENT OF QUALIFICATION
30.1 Single-type submission. Qualification will be restricted to the capacitance value and to capacitance
tolerances equal to and broader than the capacitance tolerance submitted.
30.2 Combined-type submission. Qualification within a style and dc rated voltage will be restricted to capacitance
values within the range of values submitted and, for styles where optional lead diameters are allowed, to the lead
diameter submitted. Qualification of the 5 percent or closer capacitance tolerance automatically qualifies all other
applicable capacitance tolerances. If, where applicable, 47 pF sample units are submitted, qualification will be
granted for all capacitance values equal to and less than the highest value submitted.
