1. POLICY


a. To manage risk to people, facilities, and the environment posed by flight and ground-based pressure vessels and pressurized systems (PVS) (including boilers), it is NASA policy to perform the following activities:

(1) Design, acquire, fabricate, inspect, test, install, repair and alter, operate, and maintain all ground-based PVS in accordance with the applicable codes, standards, guides, and regulations as detailed in NASA- STD-8719.17, NASA Requirements for Ground-Based Pressure Vessels and Pressurized Systems (PVS).

(2) Certify all ground-based PVS in accordance with this NPD and NASA-STD- 8719.17 prior to operation.

(3) Qualify and accept spaceflight PVS, including qualification units, in accordance with ANSI/AIAA S-080, Space Systems Metallic Pressure Vessels, Pressurized Structures, and Pressure Components, and ANSI/AIAA S-081, Space Systems Composite Overwrapped Pressure Vessels (COPV).

(4) Qualify and accept atmospheric flight (nonspaceflight) PVS in accordance with the Federal Aviation Administration regulations in Title 14 of the U.S. Code of Federal Regulations. For NASA owned or operated Department of Defense (DoD) aircraft; maintain, operate, and modify aircraft PVS in accordance with approved technical orders from the DoD cognizant agency for the aircraft.

(5) For ground-based PVS (including flight PVS converted for ground use), where it is not practical (due to age or design) to meet the requirements of paragraph 1.a(1), evaluate, certify, and accept risk for specific operational parameters in accordance with NPR 8715.3, NASA General Safety Program Requirements, this NPD, NASA-STD-8719.17, and Center policy or procedure prior to operation.

(6) For space flight PVS, where it is not practical to meet the requirements of paragraph 1.a(3), evaluate, certify, and accept risk in accordance with program management risk acceptance requirements prior to operation.

(7) Exclude categories of ground-based or specific ground-based PVS from Center PVS certification programs only after review, evaluation, and documentation (in the PVS configuration management system) of the rationale supporting the exclusion. Typical examples of excluded items that are permissible for use without certification are low-risk, off-the- shelf commercial systems that meet all applicable standards.

(8) Perform periodic inspection and recertification for all PVS to ensure their ongoing fitness for service and to document and assess relevant changes in condition or knowledge that materially affect risk assessment.

(9) Document and maintain the certification status of PVS to indicate all exceptions, waivers, nonconformances, special constraints, or instructions required for safe operation of the PVS.

(10) Ensure that PVS are operated and maintained in accordance with applicable national consensus codes and standards and by skilled, adequately trained, and qualified personnel who are certified in accordance with NPR 8715.3.

(11) Establish a configuration management program to control the engineering and maintenance changes made to PVS.

(12) Evaluate tenant and transient (e.g., construction, and not including onsite support service) contract PVS programs to determine whether they can be accepted as meeting the requirements of this NPD by providing an equivalent level of safety or if they need to be incorporated into a NASA- operated PVS program.

(13) Exceptions, adjustments, deviations, and waivers are processed in accordance with NPR 8715.3, NASA-STD-8719.17, and this NPD.
