MIL-STD-1316E
b. A feature that provides a positive means of determining that the fuzing system is not armed during and after its assembly and during installation into the
munition. Where the fuzing system is accessible after installation into the
munition, the positive means of determination shall also be available.
c. A feature that prevents installation of an armed, assembled fuzing system into a munition.
If arming and reset of the assembled fuzing system in tests is a normal procedure in manufacturing, inspection, or at any time prior to its installation into a munition, subparagraph a is not sufficient and either subparagraph b or c must also be met.
4.6.6.1 Visual indication. If visual indication of the non-armed or armed condition is employed in the fuze, visible indicators shall be designed to provide a positive, unambiguous indication of condition. Indicator failure shall not result in a false non-armed indication. If color coding is used to represent condition, the colors and coding shall be as follows:
a. Non-armed condition. Fluorescent green background with the letter S or word
SAFE superimposed thereon in white. Colors shall be nonspecular.
b. Armed condition. Fluorescent red or fluorescent orange background with the letter A or the word ARMED superimposed thereon in black. Colors shall be nonspecular.
c. Suggested color specifications.
1) Fluorescent green, Color No. 38901 per FED-STD-595.
2) Fluorescent red, Color No. 38905 per FED-STD-595.
3) Fluorescent orange, Color No. 38903 per FED-STD-595.
4.7 Documentation. The evaluation program used as the basis of the safety assessment which is prepared by the developing agency shall be documented in both detail and summary form.
4.8 Electromagnetic environments. Fuzes, in their normal life cycle configurations, shall not inadvertently arm or function during and after exposure to: electromagnetic radiation (EMR), electrostatic discharge (ESD), electromagnetic pulse (EMP), electromagnetic interference (EMI), lightning effects (LE) or power supply transients (PST). In addition, fuzes shall not exhibit unsafe operation during and after exposure to the above environments. Fuzes shall be tested or evaluated for:
a. EMR - per MIL-STD-1512 and MIL-STD-464
