NASA’s Office of Safety and Mission Assurance’s Nondestructive Evaluation program is leading a variety of agency initiatives to ensure the successful qualification of Additive Manufacturing products for deployment on future NASA missions.

Over the last seven years, Goddard Space Flight Center has experienced a massive increase in the use of inherited components, including flight-printed wiring assemblies.

An inherited component is one that either already exists or is built-to-print from an existing design. If these parts aren’t designed, manufactured, inspected, tested and delivered acceptably, they pose an elevated risk to missions.

NASA recently published an administrative change (Change 2) of NPD 8730.1C, Metrology and Calibration that went into effect on May 19, 2016. The implemented changes were developed through the Metrology and Calibration Working Group and are intended to provide increased flexibility to centers implementing the policy.

The 2016 Quality Leadership Forum, sponsored by NASA’s Office of Safety and Mission Assurance, took place in March in Cape Canaveral, Florida. One hundred and forty five attendees from NASA and other government agencies, as well as suppliers and distributors, discussed a wide range of topics that provided insight into Quality lessons learned, risks, best practices and updates to industry standards.

The United States Patent and Trademark Office granted NASA’s Office of Safety and Mission Assurance Nondestructive Evaluation (NDE) program a patent for its Electric Field Quantitative Measurement System and Method. The patent covers both the Electric Field Imaging sensor and the methods developed by Edward Generazio, NDE program manager.

NASA’s Office of Safety and Mission Assurance Nondestructive Evaluation (NDE) program recently published a Technical Manual, NASA DOEPOD [Design of Experiments for Probability of Detection] NDE Capabilities Data Book.

Dr. Jess Waller, material scientist at NASA’s White Sands Test Facility with Jacobs Technology Inc., received the 2015 Robert J. Painter Memorial Award for Meritorious Service from ASTM International and the Society for Standards Professionals for his significant contributions to standards over the last year. Waller, part of the Office of Safety and Mission Assurance’s (OSMA) Nondestructive Evaluation (NDE) program, was chosen for this award out of ASTM’s approximately 32,000 members. 

Members of NASA’s Office of Safety and Mission Assurance Nondestructive Evaluation (NDE) Working Group, along with the American Society for Testing and Materials, collaborated in the development of voluntary consensus standards for NDE of flat-panel polymer matrix composites as well as thin-walled metallic liners and overwraps in composite overwrapped pressure vessels. Before this effort, there were no comprehensive standards for NDE in these areas.

Since last December, representatives from NASA’s Office of Safety and Mission Assurance’s Nondestructive Evaluation program have provided presentations to various audiences that highlighted their efforts and new ventures related to Additive Manufacturing. 

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.
