scope:

Purpose

The purpose of this standard is to ensure the structural integrity of PVS through implementation of a minimum set of requirements for ground-based PVS in accordance with this standard, NPR 8715.1, NASA Safety and Health Programs, applicable Federal, state, and local regulations, and standards incorporated by reference. This standard also provides requirements for ground processing of flight PVS.

Applicability

This standard applies to NASA Headquarters and NASA Centers, including Component Facilities, and Technical and Service Support Centers. This standard may be cited in contract, program, and other Agency documents as a technical requirement.

This standard applies to all ground-based equipment designed for, or operating at, positive or negative gauge pressure that is not specifically excluded in 4.2 of this standard. It applies to NASA-owned or -operated, temporary or permanent, ground-based PVS and to non-NASA-owned contractor or tenant ground-based PVS operated on NASA property if that PVS is determined by the Pressure Systems Manager (PSM) to pose a risk to NASA personnel, facilities, or equipment. It specifically includes, subject to 4.2 of this standard, systems often referred to as "low pressure" such as building and facility services equipment (e.g., shop air), laboratory systems, and vacuum systems.

This standard applies to the ground processing of flight PVS as specified in 4.13 of this standard.
