APPENDIX
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. SUBMITTAL PLANS
20.1 Single type. The following details shall apply:
a. Sample size: As specified in table V.
b. Sampling criteria: Sample units of the same style, rated voltage, capacitance tolerance, operating
temperature range, insulating sleeve material (when applicable), terminal, case material and finish shall be
submitted.
c. Limits of coverage: Qualification coverage shall be extended to all lesser capacitance values and broader
capacitance tolerances in the same rated voltage. Circuit diagram 1 will qualify circuit diagram 3.
20.2 Combined type. The following details shall apply:
a. Sample size: As specified in table XI.
b. Sampling criteria: Sample units of the same operating temperature range, capacitance tolerance,
insulating sleeve material (when applicable), case material, and finish may be submitted.
c. Limits of coverage: Qualification will be extended to all broader capacitance tolerances, all capacitance
values and rated voltages between the values and ratings submitted in the same temperature range.
Circuit diagram 1 will qualify circuit diagram 3.
20.3 Impregnant. Two hundred cubic centimeters of each impregnant used in the specimens for which approval
is sought shall be submitted. On subsequent submissions, an impregnant that has successfully withstood the
flashpoint of impregnant test (see 4.7.17) need not be submitted.
