This document provides requirements for prevention of electrostatic discharge (ESD) events and for protection of hardware from ESD. The document is applicable to MSFC in-house activities for flight hardware. This document has been tailored to comply with the requirements of ANSI/ESD S20.20 as specified per NASA Policy Directive (NPD) 8730.5, NASA Quality Assurance Program Policy. The NASA-HBDK-8739.21 was also used to provide standardized guidance based on Agency-level best practices. This document provides a consistent application of requirements for an ESD control program for electrical or electronic assemblies, equipment, and their constituent parts susceptible to damage from ESD. This document shall not apply to ESD requirements for electrically initiated explosive devices. For propellant and explosive devices, reference MSFC-STD-1800 or other approved procedures.
