safe position after being bottomed with a 20 pound force and
released.
3.3.3 Rotor reset capability. - The rotor assembly in the loaded
safety and arming device shall be capable of return to the fully
safe position, after being rotated to a position of 26 degrees but
not more than 35 degrees from the fully safe position and released.
3.3.4 Arming Time. - The rotor assembly in the loaded S&A
shall rotate from the fully safe position to the fully armed
position in not less than 0.67 sec. and not more than 0.81 sec.
when subjected to arming acceleration of 27.00 plus or minus
0.25 g's.
3.3.5 Non-Arm. - The rotor assembly in the loaded S&A shall
not arm when subject to acceleration of 11.25 g's minimum for
a minimum of 3 seconds. This test shall be conducted just prior
to insertion of the S&A into the fuze body.
3.3.6 S&A position. - The safe position of the S&A shall be
verified after insertion into the fuze body assembly. After in-

3.4.1 Arming Time. - The fuze assembly shall arm in not less
than 0.63 sec. or more than 0.82 sec. when subjected to arming
acceleration of 27.00 plus or minus 0.25 g's and the detent shall
lock the rotor in the fully armed position, as determined by
radiographic inspection.
3.4.2 Non-Arming. - The fuze assembly shall not arm when
subjected to an acceleration of 11.50 g's plus or minus 0.25
g'S for a minimum of 3 seconds.
