The Design Agency approved handling procedure to preclude untested
S&A's from being introduced into the fuze prior to the booster
housing being installed shall also be assessed when the standards
are introduced. If an improper procedure is being used as
determined by the Government, all fuzes accepted subsequent to the

spin table. The equipment shall accelerate the loaded fuze in a
clockwise direction to 40.0g's plus or minus 0.5g's except for cold
temperature which shall be done at 27g's plus or minus 0.5g's and
the arming time shall be recorded to the nearest hundredth of a
second using a swing fixture and acoustic pick-up feeding the arming

table. The equipment shall accelerate the loaded fuze assembly in a
clockwise direction to 12.0g's plus or minus 0.5g's for a minimum of
three (3) seconds. An examination shall be made for rotor in the
safe position. Any fuze assembly that fails the requirements of the
non-arming time test shall be classed defective.
