Purpose

The purpose of this NASA Technical Standard is to establish the nondestructive evaluation (NDE) requirements for any NASA system or component, flight or ground, where fracture control is a requirement. This NASA Technical Standard defines the primary requirements for NDE in support of NASA-STD-5019A, Fracture Control Requirements for Spaceflight Hardware. NDE applied in-process for purposes of process control and NDE of damage tolerant composites are not addressed in this document.

It is the policy of NASA to produce aerospace flight systems with a high degree of reliability and safety. This is accomplished through good design, manufacturing, test, and operational practices, including the judicious choice of materials, detailed analysis, appropriate factors of safety, rigorous testing and control of hardware, and reliable inspection. NASA fracture control requirements stipulate that all human-rated aerospace flight systems be subjected to fracture control procedures to preclude catastrophic failure. Those procedures frequently rely on NDE to ensure that the potential failure initiation of relevant crack-like flaws are not present in critical areas.

Programs that are not human-rated may choose to impose these requirements on a mission or hardware to bolster the program or to serve as a stepping-stone for human-rating.

Applicability

This NASA Technical Standard is applicable to the fracture control of metal components, e.g., aluminum, steel, titanium, and nickel alloys for any NASA system or component, flight or ground, where fracture control is a requirement.

Conditional notes on applicability are presented in section 4.2.3.

The requirements described herein apply to fracture-critical hardware developed for NASA applications by NASA Field Centers, international partners, contractors, and outside organizations. NDE processes are required to meet the requirements in this NASA Technical Standard to screen hardware reliably for the presence of crack-like flaws.

This NASA Technical Standard is approved for use by NASA Headquarters and NASA Centers and Facilities, and applicable technical requirements may be cited in contract, program, and other Agency documents. It may also apply to the Jet Propulsion Laboratory (a Federally Funded Research and Development Center (FFRDC)), other contractors, recipients of grants and cooperative agreements, and parties to other agreements only to the extent specified or referenced in applicable contracts, grants, or agreements.

Verifiable requirement statements are designated by the acronym NER (Nondestructive Evaluation Requirement), numbered and indicated by the word "shall"; this NASA Technical Standard contains 96 requirements. Explanatory or guidance text is indicated in italics beginning in section 4. To facilitate requirements selection and verification by NASA programs and projects, a Requirements Compliance Matrix is provided in Appendix A.
