PURPOSE

The Agency-level quality requirements for ESD safety and control are defined by NPD 8730.5, NASA Quality Assurance Policy Requirements, and are wholly contained in ANSI/ESD S20.20, ESD Association Standard for the Development of an Electrostatic Discharge Control Program for - Protection of Electrical and Electronic Parts, Assemblies and Equipment (Excluding Electrically Initiated Explosive Devices). The purpose of this document is to present a standardized administrative and technical baseline for development of an organization's ESD Control Program Plan which is required by ANSI/ESD S20.20.

Note: While providing a recommended ESD Control Program Plan in a format that facilitates direct use of its text (starting at paragraph 4.3) by authors of supplier-level ESD Control Program Plans, this document also summarizes the recommendations from ESD TR20.20. Supplier-level ESD Control Program Plan authors who choose to use the text herein, in their own Plan, are encouraged to examine each use of the words "should", "will", "is", and "are" herein and, when using those clauses, change those to "shall" or "must" as needed to establish the local requirements. Uses of the word "shall" herein indicate a requirement that is traceable to ANSI/ESD S20.20.

APPLICABILITY

This publication is provided as a resource for all organizations that handle ESD-sensitive (ESDS) items for NASA projects and are subject to the requirements of ANSI/ESD S20.20.

Agency-level ESD safety and control requirements are intended to apply to all ESDS devices applied on projects where NASA high reliability aircraft or space flight hardware will be processed. This baseline should also be applied to hardware production where the end item may not be missioncritical yet is expensive to replace, or is a long-lead item.

The practices described herein are generally suitable for the ESD sensitivity levels of the Human Body Model (HBM) Classes 0 and 1A and Machine Model (MM) Class M1. For special instances where the Charge Device Model (CDM) applies, additional precautions and practices beyond those described herein may be necessary. See paragraph 8.2.
