This standarddoes not apply to electrically initiated explosive devices orpart level design requirements. MIL-HDBK-263 provides additionalinformation

5、relative to the implementation of this standard.3. Electrostatic charges are generated by the relativemotion, physical separation of materials or flow of solids,liquids, or gases. Common sources of ESD include personnel,items made of common plastics, an”dprocessing equipment. ESD candamage parts by

40、tor shall preparean ESD control program plan that addresses each of the elementsof the ESD control program shown in the tailoring flow chartdepicted in figure 1. The ESD control program plan is theprincipal document for designing, implementing, and auditing theESD control program. The goal is a full
