4.7.10 Vibration (see 3.6.3). The solenoids shall be tested in accordance with method 204 of MIL-STD-202. The
following details shall apply:
a.
Mounting: Solenoids shall be rigidly mounted by a normal mounting means in a suitable test jig. The
vibration shall be monitored on top of the test jig as near as practicable to the support points of the
solenoids.
b.
Electrical load conditions: The solenoids shall be energized with rated coil voltage (or current) for half the
required test time and deenergized for half the required test time in each of the three mutually
perpendicular directions.
c.
Test condition letter: See 3.1.
d.
Tests and measurements after vibration: After vibration, operating force (torque), compensated actuating
voltage, and deactuating voltage (or current) shall be tested as specified in 4.7.2.1, 4.7.2.2, and 4.7.2.3,
respectively. Solenoids shall be inspected externally for evidence of damage such as cracks or loosening
of parts.
4.7.11 Shock (see 3.6.4). Solenoids shall be tested in accordance with 4.7.11.1, 4.7.11.2, or 4.7.11.3, as
applicable (see 3.1).
4.7.11.1 Shock 1. Solenoids shall be tested in accordance with method 205 of MIL-STD-202. The following
details shall apply:
a.
Test condition letter: C.
b.
Electrical operating conditions: In each direction of shock, the coil shall be deenergized during two shocks
and energized with rated voltage (or current) during one shock.
c.
Measurements after shock: Following this test, the operating force (torque), compensated actuating
voltage, and deactuating voltage (current) shall be tested as specified in 4.7.2.1, 4.7.2.2, and 4.7.2.3,
respectively.
4.7.11.2 Shock 2. Solenoids shall be tested in accordance with method 213 of MIL-STD-202. The following
details shall apply:
a.
Mounting method and accessories: Normal mounting means.
b.
Test condition letter: A.
c.
Electrical operating conditions: As specified in 4.7.11.1b.
d.
Measurements after shock: As specified in 4.7.11.1c.
Following the shock test, there shall be no evidence of mechanical or electrical damage, nor shall the test impair the
normal operation of the solenoid.
4.7.11.3 Shock 3. Solenoids shall be tested in accordance with method 207 of MIL-STD-202. The following
details shall apply:
a.
Mounting fixtures: Normal.
b.
Height of hammer drop: See 3.1.
c.
Electrical operating conditions: As specified in 4.7.11.1b.
