NASA-STD-8719.17 standard is defined by NASA to ensure the integrity and safety of ground-based pressure vessels and pressurized systems (PVS). Its fundamental purpose is to establish a comprehensive framework for the design, construction, inspection, testing, and certification of these vital components. The standard's aim is to ensure that these pressure systems function optimally, without compromising the safety of personnel, equipment, and the surrounding environment.

Key Components of NASA-STD-8719.17

• Design and Fabrication: The standard enforces meticulous design principles that encompass material selection, structural integrity, and safety considerations. It mandates that these systems be designed, fabricated, and inspected by professionals possessing the requisite expertise.
• Inspection and Testing: The standard leaves no room for ambiguity when it comes to inspection and testing. It delineates the requirements for non-destructive testing, leakage testing, and pressure testing, ensuring that every aspect of these systems is thoroughly examined for any potential risks.
• Certification: NASA-STD-8719.17 places paramount importance on certification. Each ground-based pressure vessel and pressurized system must undergo rigorous certification processes, ensuring that they meet the standard's stringent requirements before being deemed fit for use.
• Maintenance and Operations: The standard's influence transcends the design and construction phases, extending to the operational lifespan of these systems. Maintenance protocols are laid out, underscoring the need for periodic inspections, testing, and re-certification to maintain ongoing safety.

Design and Construction

The cornerstone of the standard lies in its design and construction requirements for new PVS. It mandates that all fresh ground-based conventional PVS adhere to rigorous design, fabrication, assembly, erection, inspection, examination, and testing protocols in alignment with relevant Voluntary Consensus Standards (VCS) and regulations. The pressure vessels entrusted with transporting fluids under pressure must comply with the Department of Transportation (DOT) regulations of 49 CFR pt.  As a testament to precision and accountability, new pressure vessels, including heat exchangers, bear the ASME Boiler and Pressure Vessel Code (BPVC) Section code stamp, signifying compliance with rigorous industry standards. Additionally, vacuum vessels, and those undergoing alterations or repairs, operating under high vacuum service conditions, or involving external atmospheric pressure, follow specified conditions to ensure safety and functionality.

Quality Assurance

Within the context of NASA-STD-8719.17 lies the mandate for strict adherence to quality assurance. The standard ensures that every step of the manufacturing and alteration process is meticulously aligned with the quality assurance manual of the respective organization. This insistence on quality control provides an additional layer of assurance that the highest standards of safety and operational efficiency are upheld.
