A.2.1.2.3 Combined characteristics. When qualification is sought for the same impregnant or filling compound
used for two characteristics, both characteristics may be represented in a submission; however, the characteristic to
be tested shall be as specified in table A-II.

A.2.1.3 Impregnant or filling compound. A minimum of 200 cubic centimeters of each impregnant or filling
compound used in the capacitors, or a certification of the flashpoint of impregnant or filling compound measured in
A.2.1.4 Alternate case material. When qualification for specific types of capacitors has been granted and
qualification is sought for an alternate case material, 14 capacitors of the same type within the combined-style group
utilizing the alternate case material may be submitted (see A.3.5). For the purpose of establishing qualification of
alternate case material, all style groups may be considered jointly.
Where qualification has been established for capacitors enclosed in nonferrous case material, qualification may be
granted for ferrous case material, providing certification is furnished for the following:
a.
The material and applied finish of the ferrous cases shall be the same as those previously approved for some
other capacitor style.
b.
The design and construction of the ferrous cases shall be the same as that of the approved nonferrous case
of the same capacitor styles.
c.
No change shall be made in the basic design of the capacitors other than the case material.
A.2.1.5 Alternate applied finish. When qualification for specific types of capacitors has been granted in
accordance with A.3.1 and qualification is sought for an alternate applied finish, 14 capacitors of the same type
utilizing the alternate finish may be submitted (see A.3.6).
A.2.1.6 Combined alternate case material and applied finish. When qualification is sought for an alternate case
material utilizing an applied finish for which qualification has been granted, and, concurrent with this, when
qualification is sought for an alternate finish applied to a case material for which qualification has been granted, 7
capacitors of each construction but the same capacitor style may be submitted (see A.3.7).
A.3. EXTENT OF QUALIFICATION.
A.3.1 Single-type-capacitor submission. Each single-type-capacitor submission shall confer eligibility for
qualification for the combination of style, terminal, circuit, and characteristic represented, except as specified below.
The voltage-rating qualification shall be restricted to those ratings equal to and less than the rating represented in the
submission in the watt-second group represented. The watt-second-rating range of qualification shall be in
accordance with table A-III, except that when specified (see 3.1), watt-second group I is limited to capacitors having
dc voltage ratings of 1,000 volts or less, and watt-second group II includes capacitors having a watt-second rating of
0 to 0.5 which are not included in watt-second group I.
a.
A circuit may also represent other circuits, as listed below:
