unless waived in writing. The Government may perform further tests before
or after installation. Testing in general shall comply with NEMA WC 70.
Specific tests required for particular materials, components, and completed
cables shall be as specified in the sections of the above standards
applicable to those materials, components, and cable types. Tests shall
also be performed in accordance with the additional requirements specified
below.
1.5.2.1
High-Voltage Test Source
Where the applicable standards allow a choice, high-voltage tests for
cables to be used exclusively on dc circuits shall be made with dc test
voltages. Cables to be used exclusively on ac circuits shall be tested
with ac test voltages. If both ac and dc will be present, on either the
same or separate conductors of the cable, ac test voltages shall be used.
1.5.2.2
Shielded Cables Rated 2,001 Volts or Greater
The following tests shall be performed in addition to those specified
above. Section or paragraph references are to AEIC C8 or AEIC CS6 as
applicable, unless otherwise stated.
a. High potential test voltages shall be as required by Table B1 of
AEIC C8 or AEIC CS6 as applicable, rather than by NEMA WC 70.
b. If high potential testing is done with an ac test voltage as
specified in paragraph HIGH-VOLTAGE TEST SOURCE, an additional test
shall be made using a dc test voltage rated at 75 percent of the
specified full dc test voltage, for 5 consecutive minutes.
c. Production sampling tests shall be performed in accordance with
Section D. Sampling frequency and failure contingencies shall be in
accordance with paragraph G.3. Unless otherwise approved, samples
shall not be taken from the middle of extruder runs of insulation or
shielding made only for one continuous shipping length of cable, if
such sampling will result in the need to repair the sampled area.
d. Partial discharge tests shall be performed in accordance with
Section E, paragraph E.2, and Section F.
1.5.2.3
Flame Tests
All [multiple-conductor and single-conductor] cable assemblies shall pass
IEEE Std 383 flame tests, paragraph 2.5, using the ribbon gas burner.
Single-conductor cables and individual conductors of multiple-conductor
cables shall pass the flame test of NEMA WC 70. If such tests, however,
have previously been made on identical cables, these tests need not be
repeated. Instead, certified reports of the original qualifying tests shall
be submitted. In this case the reports furnished under paragraph REPORTS,
shall verify that all of each cable's materials, construction, and
dimensions are the same as those in the qualifying tests.
1.5.2.4
Independent Tests
The Government may at any time make visual inspections, continuity or
resistance checks, insulation resistance readings, power factor tests, or
dc high-potential tests at field test values. A cable's failure to pass
these tests and inspections, or failure to produce readings consistent with
acceptable values for the application, will be grounds for rejection of the
