MIL-DTL-16377J(SH)
4.8.22 Power quality test. The fixture shall be subjected to the total harmonic distortion test of
MIL-STD-1399-300.
4.8.23 Voltage transient spike test. The fixture shall be subjected to the electrical spike test of
MIL-STD-1399-300 (see 3.6.18.2).
4.8.24 Fail-safe circuit design test. One LED shall be selected at random within the luminaire, open circuit the
LED, verify all remaining LEDs remain operational and luminaire light output is not visibly degraded.
4.8.25 Type III chromaticity conformance inspection. The chromaticity testing shall be conducted at a distance
of 8 feet from the lens or window, with the detector aimed at the center of the fixture. The instrument used shall
have a minimum accuracy of ±0.002 for (x) (y) coordinates. The chromaticity shall be within the defined (x) (y)
coordinates for white, red, amber, blue, and cyan light as specified (see 3.7.4).
4.8.26 Emergency light fixture battery and charging system testing. The following procedure shall be used to
test the charging capability of an emergency light fixture. Testing shall be accomplished in a 131 °F (55 °C)
environment.
a. The battery shall be charged to its maximum charge over a period of 24 hours via 115 volts alternating
current (VAC), 60 hertz being applied to the fixture wiring. The initial voltage of the battery shall be measured.
b. The input power to the fixture shall be removed. The fixture shall now be running on battery power. The
battery voltage and ambient temperature shall be recorded every 30 minutes.
c. The fixture shall be run on battery power for 5 hours. The battery voltage, when measured after 5 hours,
shall be not less than 87.5 percent of its initial voltage.
d. 115 VAC, 60 hertz input power shall be reapplied to the fixture for 24 hours to recharge the battery to its
maximum charge.
e. The input power shall be removed and the fixture shall be run on battery power for a period of 3 hours and
20 minutes. The battery voltage, when measured after 3 hours and 20 minutes, shall be not less than 87.5 percent of
its initial voltage. The battery voltage and ambient temperature shall be recorded every 30 minutes.
f. 115 VAC, 60 hertz input power shall be reapplied to the fixture for 24 hours to recharge the battery to its
maximum charge.
g. The input power shall be removed. The fixture shall be run on battery power until the low voltage cut-off
engages. The battery voltage and ambient temperature shall be recorded every 30 minutes.
h. 115 VAC, 60 hertz input power shall be reapplied to the fixture for 24 hours to recharge the battery to its
maximum charge.
i. The input power shall be removed and the fixture shall run on battery power for 5 hours. The battery
voltage, when measured after 5 hours, shall be not less that 87.5 percent of its initial voltage. The battery voltage
and ambient temperature shall be recorded every 30 minutes.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or
order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these
personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging
requirements are maintained by the Inventory Control Point s packaging activities within the Military Service or
Defense Agency, or within the military service s system commands. Packaging data retrieval is available from the
managing Military Department s or Defense Agency s automated packaging files, CD-ROM products, or by
contacting the responsible packaging activity.
