in 4.3.1 and the sampling tests in 4.3.2.
4.3.1 Individual tests. Each dummy converter shall be subjected to the following
examination and tests:
a. Examination of product (see 4.6.1).
b. Capacitance at room temperature (see 4.6.2).
4.3.2 Sampling tests. One percent of each order (a minimum of one dummy converter),
shall be subjected to the following tests:
a. Capacitance at low temperature (see 4.6.3).
b. Capacitance at high temperature (see 4.6.4).
c. Case leakage (see 4.6.5).
4.4 Inspection conditions. Unless otherwise specified, all tests shall be performed at
ambient temperature and pressure, and not greater than a relative humidity of 80 percent.
4.5 Requirements cross-reference matrix. Table I provides a cross-reference
matrix of the section 3 requirements tested or verified in the paragraphs below.

4.6 Tests.
4.6.1 Examination of product. Each dummy converter shall be examined to
determine conformance to materials, weight, and dimensions.
4.6.2 Capacitance at room temperature. Using a capacitance measuring instrument, the
capacitance at room temperature shall be 123.5 ± 1.0 pF for Type I dummy converters and
303.5 ± 2.5 pF for Type II dummy converters.
4.6.3 Capacitance of low temperature. The dummy converter shall be cold soaked at a
temperature not greater than -65°F for no less than 8 hours. While still at this temperature, the
capacitance shall be 123.5 ± 1.0 pF for Type I dummy converters and 303.5 ± 2.5 pF for Type
