The Office of Safety and Mission Assurance’s Workmanship Standards program recently updated NASA-STD-8739.6, Implementation Requirements for NASA Workmanship Standards to

• Align with changes in industry standards
• Expand Electrostatic Discharge (ESD) control requirements
• Clarify training requirements
• Reflect changes in other NASA Policy Directives and NASA Procedural Requirements

In light of the logistical and safety constraints put upon NASA’s suppliers and training facilities due to COVID-19, NASA’s Office of Safety and Mission Assurance released its second memo, which endorses, with caveats, the extension of training credential validity periods for the majority of operators and inspectors employed by organizations who seek to comply with NASA Workmanship Standards for the assembly and Quality Assurance of NASA hardware. This extension is only applicable to individuals whose training credentials would have expired on or after Feb. 15, 2020. 

The NASA Workmanship Standards Program has released a new course in SATERN as a part of the NSC STEP Training that provides an overview of NASA-STD 8739.6, Implementation Requirements for NASA Workmanship Standards. The course, “8739.6 Self-Paced Workmanship Training,” is intended to inform and familiarize NASA employees with the NASA standard without replacing the need to read the content of the standard or participate in traditional Workmanship training.

It is essential that NASA engineers use proper precautions when working with Electrostatic Discharge (ESD) sensitive hardware, as poor ESD control practices could be the difference between success and failure for a mission. ESD control is a fundamental component of NASA’s workmanship policy, which is why NASA requires operators to verify ESD personnel grounding systems (e.g. wrist or heel straps that are continuously connected to common point ground) are properly functioning before they enter an ESD Protected Area (EPA) or come within one meter of an ESD sensitive item. 

Multi-disciplinary physics-of-failure testing and simulations conducted on Printed Circuit Boards at Goddard Space Flight Center recently resulted in an industry standard update, which will lead to cost savings not only for NASA but for the electronics industry in general.

The NASA Workmanship Standards Program coordinated an administrative change to NASA-STD-8739.6A, Implementation Requirements for NASA Workmanship Standards. The primary reason for the change is to formally adopt IPC/WHMA-A-620B-S, Space Applications Electronic Hardware Addendum to IPC/WHMA-A-620B as an equivalent, alternative standard to NASA-STD-8739.4, Workmanship Standard for Crimping, Interconnecting Cables, Harnesses, and Wiring.  

NASA-STD-8739.6A, Implementation Requirements for NASA Workmanship Standards was updated and released on June 30, 2016. The revised standard, effective for five years, includes significant technical updates and corrections. This update was one of three recently publish standard updates, which included NASA-STD-8739.1B, Workmanship Standard for Polymeric Application on Electronic Assemblies and NASA-STD-8739.4A, Crimping, Interconnecting Cables, Harnesses, and Wiring.

NASA-STD-8739.4A, Crimping, Interconnecting Cables, Harnesses, and Wiring was updated and released on June 30, 2016. The revised standard, effective for five years, includes significant technical updates and corrections. This update was one of three recently publish standard updates, which included NASA-STD-8739.1B, Workmanship Standard for Polymeric Application on Electronic Assemblies and NASA-STD-8739.6A, Implementation Requirements for NASA Workmanship Standards.

NASA-STD-8739.1B, Workmanship Standard for Polymeric Application on Electronic Assemblies was updated and released on June 30, 2016. The revised standard, effective for five years, includes significant technical updates and corrections. This update was one of three recently publish standard updates, which included NASA-STD-8739.4A, Crimping, Interconnecting Cables, Harnesses, and Wiring and NASA-STD-8739.6A, Implementation Requirements for NASA Workmanship Standards.

NASA published an updated version of NASA-STD-8739.5, Workmanship Standard for Fiber Optic Terminations, Cable Assemblies, and Installation, on Sept. 14, 2015. This update adds an exclusion and a new requirement in addition to meeting agency requirements to periodically check and refresh the standard.
