seconds "on" and two seconds "off". A cycle for the hazard warning switch shall consist of the
lever movement from neutral to hazard warning position and return to neutral.
4.4.3.5 Transient capability. To determine conformance to 3.4.8, the flasher shall be
subjected to a properly polarized transient voltage of 80 Vdc for 50 ±5 milliseconds duration.
The voltage shall be applied to the input terminals of the flasher unit ten consecutive times at one
minute intervals. The flasher unit shall subsequently be subjected to and pass the tests as
specified in 4.4.3.1.
4.4.3.6 Electromagnetic interference. To determine conformance to 3.4.9, the control
and flasher units shall be tested as specified in MIL-STD-461 (see 4.4.1).
4.4.4 Mechanical.
4.4.4.1 Actuation. To determine conformance to 3.5.1, the control unit shall be mounted
in a vise or other suitable means. With the lever in one extreme position, a force shall be
gradually applied within 0.5 in. of the end of the lever in line with the direction of motion of
lever until it actuates. A force shall again be gradually applied in the same direction until the
lever actuates again. A force shall be applied to the control lever in the opposite direction until
the lever is in neutral position, and again until the lever is in the original position. This
procedure shall be repeated ten times. The average force necessary to actuate the control lever
shall not exceed the limits specified in 3.5.1.
4.4.4.2 Strength, control unit. To determine conformance to 3.5.2, the control unit shall
be mounted on a fixture equipped with a vertical bar 1.5 in. in diameter. The control unit shall
be attached to the bar to simulate normal mounting on a vehicle steering column. With the lever
hazard lock released and the lever in the farthest forward actuating position, a 70 pound force
(lbf) shall be applied gradually in line with the actuation motion of the lever. The force shall be
applied for two minutes at right angles to the lever at a point 1.5 in. from the end of the lever.
The lever shall then be placed at the opposite end of the actuation range and a 70 lbf applied as
before. The lever shall then be returned to the neutral position and the 70 lbf shall be applied in
both directions perpendicular to the plane of normal lever actuation.
4.4.5 Environmental.
4.4.5.1 High temperature.
4.4.5.1.1 Control unit. To determine conformance to 3.6.1.1, the control unit shall be
connected in a directional signal light circuit consisting of a flasher unit, ten AA52463-B10
lamps, 28 Vdc power source, and the necessary wiring. The control unit shall be stored in an
ambient temperature of 160±5F for 24 hours and then cycled for 1000 cycles at that
temperature. Control unit cycling shall be conducted in the following sequence: 1 ±0.1 second in
neutral position, 1 ±0.1 second in right turn position, 1 ±0.1 second (again) in neutral position,
and 1 ±0.1 second in left turn position (15 cycles per minute). Cycling shall be accomplished by
