This NASA Technical Standard provides an Agency-wide basis from which test programs and procedures are developed for NASA vehicles, subsystems and their components, and payloads. This Standard defines a set of space flight hardware leak test requirements that provide the necessary verification of pressure integrity for NASA vehicles, subsystems and their components, and payloads (both pressurized and sealed). Compliance of qualification and acceptance test programs and procedures with this Standard will provide consistency across the Agency and its contractors, facilitating the sharing of hardware between Centers and programs.

This Standard has been developed for vehicles, subsystems and their components, and payloads that will operate in space environment (Earth’s orbit and beyond) but may be tailored to include other operating environments. The leak test methods included are generally regarded as the most critical and the ones having the highest cost and schedule impact. This Standard specifies test levels, factors, margins, durations, and other parameters. In some cases, these specifics are expressed statistically or are referenced in other NASA standards.
