MIL-DTL-2212K(SH)
4.6.6 Inclination. Equipment shall pass an examination and general operation test as specified herein when
inclined from the bulkhead mounted orientation to the following positions at the maximum angles specified in
3.17.7 (45 for surface ships and 60 for submarines). Tests shall be conducted at nominal voltage and frequency
except where noted. Controllers shall be subjected to the voltage variation test specified in 4.6.12 at each of the four
test positions. When tested individually, contactors and relays, including time delay relays, shall be subjected to the
pickup and dropout test specified in 4.6.11 at each of the four test positions. Other devices as specified in 4.6.6.1
through 4.6.6.3 shall conform to the tests described herein and function in each of the following test positions:
a.
45 (60) degrees from vertical forward.
b.
45 (60) degrees from vertical backward.
c.
45 (60) degrees from vertical to the left.
d.
45 (60) degrees from vertical to the right.
4.6.6.1 Time delay relays. Time delay relays shall be adjusted to any convenient setpoint for inclination
testing. At each position, time delay relays will be operated. The set time delay shall not change and the setpoint
repeatability and variation of the indicated time delay shall conform to 3.16.4.3.
4.6.6.2 Pressure switches. Pressure switch setpoints shall be adjusted to 50±5 percent of the range. At each
position, pressure shall be applied to the pressure switch and shall be varied between 10 percent above the setpoint
and 10 percent below the reset point. Performance shall meet the requirements of 3.16.6.1.
4.6.6.3 Temperature switches. Temperature switch setpoints shall be adjusted to 50±5 percent of the range.
Temperature switches shall be actuated at each position. Performance shall meet the requirements of 3.16.6.2.
4.6.7 Insulation resistance. The measuring instrument used shall have an open circuit voltage of 500 VDC
±10 percent. Measurement shall be made between all mutually insulated points and between insulated points and
ground (see 3.17.4).
4.6.8 Dielectric. Dielectric tests shall be conducted in accordance with NEMA ICS 1 with a test voltage (rms)
of 1000 V plus (2X nominal voltage rating) for controllers, contactors, and all associated switching devices
(see 3.17.5).
4.6.9 Effectiveness of enclosure. Enclosures shall be subjected to the applicable test conditions (see 6.2)
specified in MIL-STD-108 to determine conformance to 3.16.16.
4.6.10 Noise, AC contactors and relays (if applicable). Noise tests shall be conducted to determine
conformance to the requirements specified in 3.17.10. AC contactors and relays shall be noise tested in the
operating mode.
4.6.11 Pickup and dropout voltage. Contactors and relays shall be connected to a voltage supply that can be
varied from 0 to 110 percent of the rated voltage to determine pickup and dropout voltages. Performance shall be in
accordance with 3.17.9. The pickup and dropout voltage test for qualification and conformance shall be conducted
with the contactor or relay operating at maximum temperature, unless the tests are being performed as part of
another test.
4.6.12 Voltage variation. Controllers shall be connected to a voltage supply that can be varied from 0 to
110 percent of the controller rated input voltage to determine conformance to 3.4.1 and 3.4.2. The controller shall
not malfunction due to the input voltage varying between 80 and 110 percent of rated value. An examination and
general operation test shall be performed at the low and high points to determine that the controller operates
properly.
4.6.13 Terminal strength. The terminals of the contactors and control relays shall be tested in accordance with
torque test Method 211A of MIL-STD-202 (see 3.17.6).
