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

The purpose of this standard is to establishcomprehensive requirements for an ESD control program to minimizethe effects of E
15、SD on parts, assemblies, and equipment. Aneffective ESD control program will increase reliability anddecrease both maintenance actions and lifetime costs. Thisstandard shall be tailored for various types of acquisitions.1.2 a. This standard defines the performancerequirements for an ESD control prog
16、ram for electrical andelectronic parts, assemblies, and equipment, susceptible todamage from ESD. Electrically initiated explosive devices andpart level design are excluded from these requirements. Thisstandard covers identification, testing, classification, assemblyand equipment design criteria, pr
17、otected areas, handlingprocedures, training, marking of hardware, protective coveringand packaging, and provides for quality assurance requirements,audits and reviews.1.3 Application. This standard shall apply to Governmentactivities and contractors, subcontractors, suppliers, andvendors. When this

Contractors shall establish, implement, anddocument the ESD control program in accordance with therequirements of this standard. Contractors shal
37、l also apply theESD control program requirements (see 5.1.1) to subcontractors,suppliers, and vendors to provide continuous protection for ESDSparts, assemblies and equipment. Detailed guidance forestablishing, implementing, documenting, and auditing theelements of an ESD control program is provided
38、 in MIL-HDBK-263.4.1.1 Tailoring of this standard. This standard, orportions thereof, may not apply to all acquisitions orapplications. The contractor shall tailor the ESD controlprogram for the acquisition by selecting the applicable elementsof figure 1. The reference numbers in figure 1 are includ

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
