Purpose

The purpose of this standard (STD) is to specify the cleanliness levels and the minimum contamination control requirements (processing, handling, protection, and test/inspection) for surfaces that come in contact with any fluid medium. These requirements pertain to the "critical surfaces" of parts, items, components, equipment, assemblies, subsystems, and systems used for NASA's rocket propulsion test program.

Applicability

a. This standard is applicable to ground-based rocket propulsion test facilities for propellant, pressurant, pneumatic, and hydraulic systems that require cleanliness certification. Specifically, these are the test stands and facilities under the purview of the NASA Rocket Propulsion Test (RPT) Program.

b. All system and product cleanliness levels shall meet or exceed program or test article requirements. Program- or customer-specified requirements may impose additional cleanliness or process requirements. In such situations, process changes and supplemental procedures may be required to satisfy any additional program- or customer-specified requests.

c. This standard may be cited in contract, program, and other Agency documents as a technical requirement.

d. Mandatory requirements are indicated by the word "shall."

e. Tailoring of this standard for application to a specific program or project shall be approved by the Technical Authority for that program or project.
