MIL-F-63281A (AR)
3.7.2.2 Low temperature arming. The S&A device after being
conditioned at a temperature of -60° ± -5°F, for 3 hours
minimum, shall arm between 0.92 and 1.19 seconds when subjected to
an arming acceleration of 27.0 ± 0.5g.
The S&A device after being
3.7.2.3 High temperature arming.
conditioned at a temperature of +155° ± 5°F, for 3 hours minimum,
shall arm between 0.92 and 1.19 seconds when subjected to an arming
acceleration of 40.0 ± 0.5g.
3.7.3 S&A position. The safe position of the S&A shall be
verified just before insertion into the fuze body. After insertion
of the S&A, fuze handling shall be controlled to preclude any chance
of inadvertent arming or substitution of the S&A until assembly of
the booster housing.
3.7.4 Load test of detonator. The detonator shall not move
more than .005 inch when a push out force of 5 pounds is applied to
the detonator socket.
3.8 Fuze assembly.

assembly, after conditioning at a temperature of 70° ± l5°F, for
2 hours minimum, shall arm between 0.88 and 1.25 seconds when
subjected to an arming acceleration of 40.0 ± 0.5g.
3.8.1.2 Low temperature arming time. The fuze assembly, after
being conditioned at a temperature of -60° ± -5°F, for 8 hours
minimum, shall arm between 1.08 and 1.65 seconds when subjected to
an arming acceleration of 27.0 ± 0.5g.
3.8.1.3 High temperature arming time. The fuze assembly, after
being conditioned at a temperature of +155° ± 5°F, for 8 hours
minimum, shall arm between 0.88 and 1.25 seconds when subjected to
an arming acceleration of 40.0 ± 0.5g.
(Fuze unarmed) - The
3.8.2 Charge circuit continuity.
continuity of the charge circuit, through its umbilical, shall be
220 ohms minimum and 3.3k ohms maximum.
The fuze assembly shall be charged

through its umbilical terminals, armed in accordance with fuze
requirement 3.8.1.1 and shall, upon the closure of its canopy
switch, exhibit corresponding function time delays as shown in Table
VI (continued), Section 4.
